Mobile Mechanic Perth

A 2017 Mazda 3 vehicle inspection Perth recently completed by CMM Automotive in Innaloo uncovered several mechanical, safety and body-related concerns. Our inspection identified an ECU fault code, poor battery condition, weak coolant, an engine oil leak, worn brakes and tyres, along with several areas of exterior damage.

A professional pre-purchase inspection gives buyers a better understanding of a used vehicle before making a purchasing decision. It can also identify upcoming repair and maintenance costs that may not become obvious during a short test drive.

Mazda 3 Diagnostic Scan

As part of this inspection, we carried out an electronic diagnostic scan of the vehicle.

The ECU contained fault code B108E, relating to a display failure. Electronic fault codes can provide useful information about problems within a vehicle and may highlight areas that require further investigation.

A fault code does not always mean a component needs immediate replacement. Correct diagnosis helps determine the actual cause before carrying out repairs.

Battery and Engine Bay Inspection

Our engine bay inspection uncovered several items requiring attention.

Testing showed that the battery was in poor condition and may require replacement. A deteriorating battery can eventually cause starting problems and may contribute to other electrical issues.

We also tested the engine coolant and found that its condition was weak. Coolant plays an important role in controlling engine temperature while also helping protect internal cooling system components.

Another significant finding involved an engine oil leak around the left side of the engine near the timing cover.

Oil leaks can vary considerably in severity and repair cost. Locating the leak during this 2017 Mazda 3 vehicle inspection Perth provided the prospective buyer with useful information before making a purchasing decision.

Front Brakes Require Attention

The steering, brake and suspension inspection identified a problem with the front brakes.

Our checks showed that the vehicle required front brake repairs. Brake condition remains an important consideration when buying a used vehicle because repairs may add to the immediate cost of ownership.

Knowing about worn brakes before purchasing also allows a buyer to consider the repair costs when assessing the overall value of the vehicle.

Rear Tyres Require Replacement

At the rear of the Mazda 3, we identified two tyres requiring replacement.

Good tyre condition contributes to safe braking, steering and handling. Tyres can also represent a considerable expense when they require replacement shortly after purchasing a vehicle.

Checking all four tyres forms an important part of our mobile pre-purchase vehicle inspections across Perth.

Mazda 3 Body and Panel Condition

Several cosmetic and body-related problems were present around the front of the vehicle.

The park light lenses showed noticeable fading. We also found panel damage around the bumper and guard, along with additional marks on the front bumper.

Further inspection revealed a dent in the left-hand front guard.

Documenting existing panel and cosmetic damage helps give the prospective buyer a clearer picture of the vehicle’s overall condition. It can also help prevent confusion about existing damage after completing the purchase.

Mazda 3 Road Test

A road test provides valuable information about how a vehicle performs under normal driving conditions.

During the road test, this Mazda 3 pulled to the left.

Several issues can cause a vehicle to pull towards one side, including tyre condition, wheel alignment, suspension problems or other steering-related concerns. Further investigation would help determine the exact cause.

This road test finding was particularly relevant because the vehicle also required two tyres.

Why a Pre-Purchase Inspection Matters

This 2017 Mazda 3 vehicle inspection Perth demonstrates how an inspection can identify several different problems before a customer purchases a used vehicle.

Our inspection uncovered a display-related ECU fault code, poor battery condition, weak coolant and an engine oil leak near the timing cover. The Mazda also required front brake repairs and two tyres. In addition, we documented several areas of body and cosmetic damage.

If you’re considering buying a Mazda 3 or another used vehicle, arranging a professional inspection before completing the purchase can help identify potential problems and upcoming repair costs.

Frequently Asked Questions

Should I get a used Mazda 3 inspected before buying?

Yes. A pre-purchase inspection can identify mechanical, electrical, brake, tyre and body concerns before you commit to purchasing the vehicle.

Can an inspection identify engine oil leaks?

Yes. We inspect the engine bay for visible signs of engine oil and other fluid leaks that may require further investigation.

Does CMM Automotive provide vehicle inspections in Innaloo?

Yes. CMM Automotive provides mobile pre-purchase vehicle inspections in Innaloo and throughout many areas of Perth.

A Toyota LandCruiser vehicle inspection in Kingsley identified several mechanical and maintenance issues that a potential buyer would want to consider before purchasing the vehicle.

CMM Automotive inspected the LandCruiser’s interior, engine bay, batteries, cooling system, steering, suspension, brakes, body and general road-test performance.

The inspection identified low battery condition, poor coolant condition, worn suspension bushes, leaking swivel hubs and scored rear brake discs.

Brake Pedal Pad Missing

Inside the Toyota LandCruiser, we found that the front brake pedal was missing its rubber pad.

This is a relatively small problem compared with other mechanical issues on the vehicle

However, an inspection should document smaller defects as well as larger mechanical concerns.

Recording everything we find gives the potential buyer a more complete picture of the vehicle’s overall condition.

Both LandCruiser Batteries Tested Low

Testing in the engine bay found that both batteries tested low.

Many LandCruisers use a dual-battery arrangement, depending on the model and vehicle setup.

Battery condition is worth checking because weak batteries can eventually contribute to starting problems and unreliable electrical operation.

Knowing the condition of both batteries before purchasing the vehicle also allows the buyer to consider potential replacement costs.

Coolant Tested Pink and Acidic

Testing the engine coolant identified another maintenance concern.

The coolant was pink in colour but tested acidic.

Coolant condition involves more than simply checking whether there is fluid in the cooling system.

Over time, coolant can deteriorate and lose some of the properties designed to protect cooling-system components.

Poor coolant condition may indicate that the cooling system requires maintenance.

For a potential buyer, this information is useful when considering the vehicle’s service history and future maintenance requirements.

Worn Front Control Arm Bushes

Inspection of the front steering and suspension found worn control arm bushes.

Control arm bushes help locate suspension components while allowing controlled movement as the suspension operates.

As bushes deteriorate, they can contribute to unwanted suspension movement and may affect vehicle handling, alignment and tyre wear.

In this LandCruiser, the control arm bushes had excessive wear and required attention..

Swivel Hubs Leaking Oil

We also found oil leaking from the swivel hubs.

Swivel hub leaks are worth identifying on a used four-wheel drive because repairing them can involve additional labour and parts.

Further inspection can determine the severity of the leak and identify the repairs needed.

Finding these leaks during the inspection gave the potential buyer the opportunity to consider the issue before purchasing the LandCruiser.

Rear Brake Discs Scored

Inspection of the rear braking system found scoring on both rear brake discs.

Brake discs should have their overall condition assessed alongside brake pad wear.

Scoring can develop for several reasons. The disc condition can help determine whether the brakes need repairs.

This represents another potential maintenance or repair cost for the buyer.

Missing Rear Hubcap

The left-hand rear hubcap was also missing.

This is a relatively minor item compared with worn suspension components or leaking swivel hubs.

However, smaller missing components still affect the overall condition and presentation of a used vehicle.

Including them in the inspection report gives the buyer a more complete record of what was found.

Minor Marks on the Roof

Inspection of the LandCruiser’s body found minor marks on the roof.

Body and paint condition can be particularly important when assessing a used four-wheel drive because these vehicles may have been used in environments where scratches and other cosmetic damage are more likely.

In this case, we recorded the roof marks as part of the overall vehicle assessment.

Noisy Tyres During the Road Test

During the road test, the tyres produced noticeable road noise.

Tyre noise can have several possible causes, including tyre design, tread condition and uneven wear.

Further inspection may be required if the noise is excessive or unusual.

The important point for the potential buyer was knowing about the noise before purchasing the vehicle.

A short drive by a buyer may not always reveal the significance of unusual noises, particularly when their attention is focused on many other aspects of the vehicle.

Why a LandCruiser Pre-Purchase Inspection Matters

Used Toyota LandCruisers can represent a significant purchase, particularly when considering the additional costs that may follow if maintenance or repairs are required.

This Kingsley LandCruiser had several findings worth considering.

Both batteries tested low, the coolant tested acidic, the front control arm bushes were worn, the swivel hubs were leaking oil and both rear brake discs showed scoring.

The inspection also identified several smaller issues, including the missing brake pedal pad, missing rear hubcap and minor roof marks.

CMM Automotive provides mobile pre-purchase vehicle inspections in Perth to help buyers understand the condition of a vehicle before making a purchase.

Toyota LandCruiser Inspection in Kingsley

A vehicle can start, drive and appear presentable while still having mechanical and maintenance requirements underneath.

This Toyota LandCruiser is a good example.

The inspection gave the potential buyer information about the batteries, cooling system, suspension, hubs, brakes, tyres and body condition before they made their purchasing decision.

That information can also help a buyer consider potential repair costs when deciding whether the vehicle and asking price are right for them.

If you’re considering buying a used Toyota LandCruiser, contact CMM Automotive on 1800 888 990 to arrange a mobile pre-purchase vehicle inspection.

A Volkswagen vehicle inspection Perth CBD callout identified several mechanical and general condition issues that a potential buyer would want to consider before purchasing the vehicle.

CMM Automotive inspected the Volkswagen’s interior, engine bay, steering, brakes, suspension, tyres and body condition. We also road tested the vehicle to identify problems that may not appear during a stationary inspection.

The inspection revealed several oil weeps, worn front tyres, brake disc wear, roof damage and an unusual whining noise from the rear of the vehicle.

Volkswagen Interior Condition

Inspection of the vehicle’s interior found damage to the rear carpets.

Interior condition can sometimes receive less attention than mechanical components when someone is buying a used vehicle.

However, damaged trim, carpets and other interior components can affect the overall condition and value of a vehicle.

Recording these items gives the potential buyer a more complete understanding of what they’re considering purchasing.

Oil Weep From Turbo Feed Pipe

Inspection of the engine bay identified a slight oil weep from the turbo feed oil pipe.

Turbocharger lubrication is important because the turbo operates at very high speeds and temperatures.

An oil weep doesn’t necessarily mean a major failure is occurring, but identifying the source allows the buyer to investigate the issue further and consider any repair that may be required.

We also found an additional oil weep around the turbo inlet cover.

Engine Oil Weeps

The turbo wasn’t the only area showing signs of engine oil.

Inspection also found a slight oil weep around the sump plug area.

The engine oil level sensor area also showed signs that warranted attention.

Small oil weeps can sometimes remain relatively minor for extended periods. However, they should still be documented during a pre-purchase inspection.

Further inspection can determine the severity and whether repairs are required.

Front Tyres Worn Out

Both front tyres were low on tread and considered worn out.

Tyres are one of the most important wear items to assess when inspecting a used vehicle.

Replacing two tyres immediately after purchasing a car represents an additional expense for the buyer. Their condition can also affect grip, braking and wet-weather performance.

Checking tyre wear before purchase therefore provides both safety and financial information.

Front Brake and Disc Condition

The front brake pads had approximately 70% remaining.

While the brake pads still had useful life remaining, inspection of the right-hand front brake disc identified a significant lip around the disc.

Brake pad thickness is only one part of assessing a braking system.

Disc condition also matters, which is why inspecting the braking components rather than simply estimating pad life provides a better picture of their overall condition.

Volkswagen Body and Roof Damage

Inspection of the body identified damage around the roof seal area.

We also found small dents in the roof above the left-hand rear door.

Body damage can range from minor cosmetic imperfections to evidence that warrants further investigation.

Documenting visible damage allows the buyer to consider the vehicle’s cosmetic condition alongside its mechanical condition.

Whining Noise During the Road Test

One of the more interesting findings appeared once we road tested the Volkswagen.

We could hear a whining noise coming from the rear of the vehicle.

A rear whining noise can have several possible causes. Without further diagnosis, it would be inappropriate to assume which component was responsible.

Instead, the inspection recorded the noise so the potential buyer knew that further investigation may be required.

This is a good example of why a road test forms an important part of a vehicle inspection when conditions allow.

Why Road Testing a Used Vehicle Matters

Some vehicle problems aren’t obvious while the car remains stationary.

Noises may only develop at particular road speeds or when components are under load.

A road test can also help identify concerns involving steering, braking, transmission operation, suspension and general vehicle behaviour.

In this Volkswagen, the rear whining noise provided the buyer with information they may not have discovered simply by looking around the vehicle.

Why a Pre-Purchase Vehicle Inspection Helps

This Volkswagen inspection found issues in several different areas.

The vehicle had oil weeps around engine and turbo components, worn front tyres, brake disc wear, roof damage and an unusual rear whining noise.

Some findings may require relatively straightforward maintenance. Others may justify further diagnosis before the buyer decides whether to purchase the vehicle.

Our mobile inspection service allows us to inspect vehicles at suitable locations throughout the Perth metropolitan area.

Volkswagen Pre-Purchase Inspection in Perth CBD

Buying a used vehicle involves more than deciding whether the car looks good and feels acceptable during a short drive.

A systematic inspection can identify mechanical concerns, maintenance requirements and visible damage that may affect the buyer’s decision or future ownership costs.

This Volkswagen in Perth CBD is a good example. Several issues became apparent only after checking different areas of the vehicle and completing the road test.

If you’re considering buying a used vehicle, contact CMM Automotive on 1800 888 990 to arrange a mobile pre-purchase vehicle inspection.

A Hyundai Veloster vehicle inspection identified several mechanical, electrical and general condition issues that a potential buyer would want to know about before purchasing the vehicle.

CMM Automotive inspected the Veloster’s interior, engine bay, cooling system, steering, brakes, tyres, body and electrical components. We also carried out a road test to assess how the vehicle operated.

The inspection revealed several areas requiring attention, including a poor battery, signs of coolant leakage, a leaking power steering pump, worn front tyres and low front brakes.

Hyundai Veloster Interior Condition

The vehicle’s interior showed several signs of wear.

The right-hand front carpet was worn and stained. We also found stains on other carpet areas and the roof lining.

Although these are primarily cosmetic issues, interior condition can provide useful information when assessing how a used vehicle has been maintained.

We also identified two functional problems inside the vehicle.

The rear door keyless entry wasn’t working correctly, while a rear seatbelt would stick when retracting.

A seatbelt that doesn’t operate smoothly deserves attention because seatbelts form an important part of the vehicle’s safety system.

Poor Battery Test Result

Testing in the engine bay found that the battery tested poorly.

A weak battery may continue starting a vehicle for some time before eventually failing. Battery condition can also affect various electrical systems, particularly when available voltage becomes low.

Knowing that the battery tested poorly gives a potential buyer the opportunity to allow for replacement or further testing.

Signs of Cooling System Problems

The cooling system presented several findings worth investigating.

The radiator cap appeared swollen, and we found minor water or coolant staining around the upper and lower radiator hoses.

There were also signs of staining around the thermostat area.

Coolant staining can indicate that coolant has escaped from the cooling system at some stage. However, further testing may be required to determine whether an active leak is currently present and identify its exact source.

Cooling-system problems shouldn’t be ignored because maintaining the correct engine operating temperature is important for reliability.

Power Steering Pump Leak

Inspection of the engine bay also identified a leaking power steering pump.

A power steering fluid leak can gradually reduce the fluid level and may eventually affect steering assistance.

The location and severity of a leak should be assessed before deciding what repairs are required.

Finding the leak during a pre-purchase inspection allows the buyer to consider the potential repair before committing to the vehicle.

Front Tyres and Brakes

The front tyres showed significant wear and required attention.

We also estimated that the front brakes had approximately 20% remaining.

This means the buyer would need to consider front brake replacement in the relatively near future, depending on vehicle use and further assessment.

Brakes and tyres are normal wear items, but replacing several components shortly after purchasing a vehicle can add considerably to the overall cost.

Rear Brakes and Spare Tyre

The rear brakes also showed wear.

The spare tyre had low remaining tread and would need attention.

A spare tyre is easy to overlook when buying a used vehicle because it isn’t normally visible during a quick inspection.

However, discovering a worn spare tyre during a roadside tyre problem isn’t ideal. Checking it during a vehicle inspection gives the buyer the opportunity to address the issue beforehand.

Lights, Locks and Body Condition

Several additional problems appeared during the exterior inspection.

The headlight lens showed discolouration, and the right-hand park light wasn’t operating.

We also found that the front door lock wasn’t working correctly.

The body panels had minor dents and scratches, while the bumper showed minor paint damage.

These cosmetic findings may not affect the mechanical operation of the vehicle, but documenting them helps provide a more complete picture of its condition.

Cruise Control Not Working

During the road test, we discovered that the cruise control wasn’t operating.

Several different faults can prevent cruise control from working correctly, so further diagnosis would be required to determine the exact cause.

The important point for the potential buyer was knowing about the problem before purchasing the vehicle.

Without a proper road test, this type of fault could easily go unnoticed.

Why a Pre-Purchase Inspection Can Save Surprises

This Hyundai Veloster demonstrates why inspecting a used vehicle involves much more than checking whether the engine starts and the car looks presentable.

The inspection identified a poor battery, cooling-system concerns, a leaking power steering pump, worn tyres, low brakes and several electrical and cosmetic problems.

None of these findings should automatically determine whether someone buys the vehicle.

Instead, they give the buyer useful information about its condition and potential future repair costs.

CMM Automotive provides mobile pre-purchase vehicle inspections in Perth to help buyers better understand the condition of used vehicles before making a purchase.

Our mobile inspection service allows us to assess vehicles at suitable private residences, dealerships and other locations throughout Perth.

Hyundai Veloster Pre-Purchase Inspection

A used Hyundai Veloster may appear to drive reasonably well during a short test drive while still having problems that aren’t immediately obvious.

Checking the vehicle systematically can reveal maintenance requirements, leaks, electrical problems and safety-related concerns.

The buyer can then consider those findings alongside the asking price and overall condition of the vehicle.

If you’re considering buying a used vehicle, contact CMM Automotive on 1800 888 990 to arrange a mobile pre-purchase vehicle inspection.

A Holden Ute vehicle inspection in Scarborough identified several issues worth considering before purchasing the vehicle. CMM Automotive inspected the ute’s interior, engine bay, brakes, tyres, body and general performance during a road test.

Some areas remained in reasonable condition, while other findings required further investigation or attention.

The inspection also highlighted an important point about buying a used vehicle. Small problems can add up, particularly when several repairs or maintenance items need attention after purchase.

Rear Tray Cover Would Not Lock

One of the first problems we found involved the Holden Ute’s rear tray cover.

We were unable to lock the cover correctly.

A lockable tray is particularly useful on a ute because owners often use the rear section to carry tools, equipment and personal belongings.

A locking problem may not affect how the vehicle drives, but it can reduce the security and usefulness of the tray.

The rear tailgate also had a locking problem, giving the potential buyer another issue to consider.

Engine Noise During Inspection

Inspection of the engine and engine bay identified a minor noise coming from the front area of the engine.

We also noticed a ticking noise when the engine started.

Engine noises can have many possible causes. Their importance depends on where the sound originates, when it occurs and whether it changes as the engine warms up or engine speed increases.

Rather than assuming a particular component caused the noise, we recorded the finding so the buyer could consider further investigation if required.

Why Engine Noises Are Worth Investigating

Unusual engine noises deserve attention when assessing a used vehicle.

Some noises may have relatively simple causes, while others can indicate components that require maintenance or repair.

Listening to an engine during a cold or initial startup can also reveal sounds that become less noticeable once the engine has been running.

This is one reason a pre-purchase inspection involves more than simply driving the vehicle around the block.

Washer Bottle Required a Top-Up

The windscreen washer bottle also required additional fluid.

This was a relatively minor maintenance item compared with some of the other findings.

However, recording small issues helps provide a more complete assessment of how the vehicle has been maintained.

A vehicle inspection should document both significant concerns and smaller items that may require attention.

Holden Ute Brakes and Tyres

Inspection of the steering, brakes and suspension found the front brakes had approximately 50% remaining.

The tyres were also around the halfway point, with approximately 50% remaining on both the front and rear tyres.

These findings gave the potential buyer useful information about the expected remaining service life of these components.

Brakes and tyres are normal wear items, but knowing their condition before purchasing a vehicle can help a buyer anticipate future maintenance costs.

Body and Panel Condition

Inspection of the front bodywork found minor scratches on the left-hand front guard.

Small scratches and cosmetic marks are common on used vehicles. However, documenting them provides the buyer with a clearer picture of the vehicle’s overall condition.

The rear of the Holden also presented the previously mentioned tailgate locking problem.

No Key Available to Unlock the Vehicle

Another concern involved the vehicle’s key situation.

There was no physical key available to manually unlock the vehicle.

Many drivers rely almost entirely on remote locking systems. However, a physical key can become important if the remote fails or the vehicle battery becomes discharged.

A missing or unavailable manual key is therefore worth identifying during an inspection.

Buzzing Noise Behind the Dashboard

During the road test, we identified another unusual problem.

A buzzing noise came from behind the dashboard when the air vent was switched on.

The ventilation system contains several components that can potentially create noises, including blower components and air-control mechanisms.

We recorded the noise rather than guessing which component had caused it.

Further investigation would be required to confirm the exact source if the buyer wanted the issue diagnosed before purchase.

Why a Pre-Purchase Vehicle Inspection Helps

Used vehicles don’t always have one major problem that determines whether they are worth buying.

Often, an inspection reveals several smaller issues that together affect the vehicle’s overall condition and potential future costs.

This Holden Ute had engine noises that deserved further investigation, locking problems with the rear tray and tailgate, no manual unlocking key and an unusual noise behind the dashboard.

At the same time, the inspection provided information about the remaining condition of the brakes and tyres.

CMM Automotive provides mobile pre-purchase vehicle inspections in Perth for buyers who want more information about a vehicle before making a purchase.

Our mobile inspection service allows us to assess vehicles at suitable locations throughout the Perth metropolitan area.

Holden Ute Inspection in Scarborough

This Holden Ute inspection in Scarborough demonstrates why checking mechanical, electrical, security and general vehicle condition can be valuable before buying a used car.

Not every finding necessarily means someone shouldn’t purchase a vehicle. The purpose of the inspection is to give the buyer more information before making that decision.

Understanding the vehicle’s condition can also help when considering potential maintenance and repair costs after purchase.

If you’re considering buying a used vehicle, contact CMM Automotive on 1800 888 990 to arrange a mobile pre-purchase vehicle inspection.

A Subaru Outback vehicle inspection in Jindalee identified several issues that would have been useful for a potential buyer to know about before purchasing the vehicle.

CMM Automotive carried out a detailed inspection of the Subaru, checking the interior, electrical systems, engine bay, brakes, suspension, tyres, body and general road-test performance.

Although some of the problems were relatively minor, the inspection also identified several areas that required further attention.

Subaru Outback Fault Codes

Electronic diagnostic testing revealed several fault codes stored in the vehicle.

These included:

• P1604 – Startability Malfunction
• C1935 – Ignition Switch Circuit Fault
• U1469 – Invalid Data Received From Auto Start
• B1012 – Battery Backup Fault

A stored fault code provides useful information during a vehicle inspection, but it doesn’t always mean a particular component should immediately be replaced.

Fault codes need to be considered alongside the condition of the vehicle, its symptoms and the results of other tests.

Finding several codes during this Subaru inspection highlighted areas that the buyer could investigate further before deciding whether to purchase the vehicle.

Poor Battery and Low Alternator Charging

Testing in the engine bay identified two important electrical concerns.

The battery tested poorly, while the alternator charging output was also low.

These findings are particularly relevant when considered alongside some of the electrical fault codes stored in the vehicle.

A weak battery can contribute to starting problems and unusual electrical behaviour. However, replacing a battery without checking the charging system can overlook another potential problem.

The alternator needs to maintain sufficient charge in the battery while the engine is operating.

Low charging performance therefore warranted further attention.

Rear Brakes and Disc Rotors Required Attention

The inspection also identified work required in the rear braking system.

The Subaru required rear brake replacement and rear disc rotors.

Brakes are an important consideration when purchasing any used vehicle because repairs shortly after purchase can add considerably to the true cost of the car.

A pre-purchase inspection can help identify this type of maintenance before the buyer commits to the vehicle.

Rear Tyres Getting Low

The Subaru’s rear tyres were also getting low.

Tyres should be assessed for more than simply whether they still contain some tread. Their overall condition, wear pattern and remaining usable life can all be important when evaluating a used vehicle.

Tyres approaching replacement represent another expense that a buyer may need to allow for after purchasing the vehicle.

Physical Keys Would Not Unlock the Doors

An unusual problem found during this inspection involved the Subaru’s physical keys.

Neither physical key would operate correctly in the driver’s or passenger’s door locks.

Modern owners may rarely use the mechanical key because they normally unlock the vehicle electronically. However, a working physical key can become important if the remote system or vehicle battery fails.

Discovering that both keys failed to operate the door locks was therefore worth recording in the inspection report.

Interior and Body Condition

Inside the vehicle, the fuse box cover would not remain securely in position and kept falling down.

The passenger-side wiper arm cover was also missing.

Inspection of the exterior found a minor impact on the rear bumper.

None of these findings alone necessarily determines whether someone should purchase a vehicle. However, recording smaller defects helps give the buyer a more complete picture of its overall condition.

Subaru Outback Road Test

A road test forms an important part of assessing a used vehicle when conditions allow.

During the road test, the Subaru drifted slightly to the left.

A vehicle pulling or drifting to one side can have several possible causes. These may include tyre condition, tyre pressures, wheel alignment or steering and suspension factors.

Further investigation can determine the exact cause if required.

Why a Pre-Purchase Vehicle Inspection Matters

A used vehicle can look presentable while still having mechanical, electrical or maintenance issues that aren’t immediately obvious.

This Subaru Outback is a good example.

The inspection identified stored electronic fault codes, a poor battery, low alternator charging, rear brake and rotor requirements, low rear tyres and several smaller concerns.

Individually, some findings may seem minor. Together, however, they provide a potential buyer with much more information about the vehicle they are considering.

CMM Automotive provides mobile pre-purchase vehicle inspections in Perth to help buyers understand a vehicle’s condition before making a purchase.

Our mobile service allows us to inspect vehicles at suitable private residences, dealerships and other locations throughout the Perth metropolitan area.

Used Subaru Outback Inspection in Jindalee

This Subaru Outback inspection demonstrates why checking more than the vehicle’s appearance and a short test drive can be valuable.

Electronic diagnostics, battery and charging tests, brake and tyre inspections and a road test revealed several areas requiring attention.

The buyer could then consider these findings when assessing the vehicle and any potential repair or maintenance costs.

If you’re considering buying a used vehicle, contact CMM Automotive on 1800 888 990 to arrange a mobile pre-purchase vehicle inspection.

A Toyota Camry faulty alternator can eventually leave the vehicle unable to continue driving. CMM Automotive recently attended a Camry that had broken down in Morley after the battery finally lost its remaining charge.

At first glance, a completely flat battery might appear to be the main problem.

However, the battery wasn’t the underlying cause of this breakdown. The alternator had stopped charging correctly, which allowed the battery to gradually discharge while the vehicle was operating.

Toyota Camry Broken Down in Morley

The Toyota Camry had reached the point where there was no longer enough electrical power available to keep the vehicle operating.

Modern vehicles rely heavily on their electrical systems. The battery provides the initial power required to start the engine, but the alternator takes over an important role once the engine is running.

When the alternator stops charging correctly, the vehicle begins relying on the electrical energy stored in the battery.

Eventually, that stored energy runs out.

What Does a Car Alternator Do?

The alternator forms an important part of a vehicle’s charging system.

Once the engine starts, the alternator generates electricity to operate many of the vehicle’s electrical systems. It also replenishes the energy used by the battery during starting.

This allows the battery to maintain sufficient charge for the next time the vehicle needs to start.

When an alternator develops a fault, the battery may continue supplying electricity for a period of time. However, it cannot do this indefinitely without receiving a charge.

Why Did the Camry Eventually Stop?

The Camry’s battery still contained some electrical energy when the alternator stopped charging correctly.

That meant the vehicle could continue operating temporarily.

As the Camry continued to use headlights, ignition systems, computers and other electrical components, the remaining battery charge gradually decreased.

Eventually, the battery voltage became too low to keep the vehicle running.

This is why a charging-system problem can sometimes appear to be nothing more than a flat battery when the vehicle finally stops.

Signs of a Faulty Alternator

Alternator and charging-system problems can produce several warning signs before a vehicle completely breaks down.

These may include:

• a battery or charging warning light
• headlights becoming dim
• electrical accessories operating unusually
• difficult starting
• repeated flat batteries
• warning lights appearing on the dashboard
• the engine eventually stopping

The exact symptoms can vary depending on the vehicle and the type of charging fault.

If a battery repeatedly becomes flat, checking the charging system can help determine whether the battery itself is actually responsible.

Flat Battery or Charging System Problem?

A flat battery and a faulty alternator can sometimes produce similar symptoms.

Jump-starting the vehicle may get the engine running again, but that doesn’t necessarily mean the problem has been solved.

If the alternator isn’t charging, the vehicle may continue running only while sufficient battery power remains.

Once that energy is depleted, the engine can stop again.

Testing the battery and charging system can help identify which component has caused the problem.

Diagnosing the Toyota Camry

CMM Automotive assessed the Camry after it broke down in Morley.

The battery had gone flat, but further investigation identified the charging system as the underlying problem.

The faulty alternator was no longer maintaining the battery’s charge.

Identifying the alternator fault was important because simply dealing with the flat battery would not have corrected the cause of the breakdown.

Roadside Assistance for Charging Problems

CMM Automotive provides mobile roadside assistance throughout Perth for starting, battery and charging-system problems.

A flat battery doesn’t always mean the battery needs replacing. Diagnosing why the battery became discharged can prevent the vehicle from breaking down again.

Our mobile service allows us to attend the vehicle at its location and investigate the problem.

For customers requiring breakdown assistance in Perth, this can help determine whether the vehicle has a battery problem, alternator fault or another electrical issue.

Toyota Camry Breakdown Assistance in Morley

This Toyota Camry breakdown is a good example of why the obvious symptom isn’t always the actual cause.

The flat battery ultimately stopped the vehicle, but the faulty alternator created the problem by failing to keep the battery charged.

CMM Automotive provides roadside and breakdown assistance throughout Morley and surrounding Perth suburbs.

If your vehicle won’t start, has a flat battery or develops an unexpected electrical problem, contact CMM Automotive on 1800 888 990 for assistance.

A Nissan not running on all cylinders can develop noticeable engine vibration, poor performance and rough running. CMM Automotive recently attended a Nissan in Bullsbrook after the vehicle developed an engine running problem.

The Nissan wasn’t operating correctly and the engine appeared to be misfiring.

Rather than continuing to drive the vehicle and hoping the problem would disappear, the owner arranged assistance so we could investigate the cause.

Nissan Running Rough in Bullsbrook

An engine relies on each cylinder operating correctly to produce smooth and consistent power.

When one cylinder stops contributing properly, the engine can begin shaking or running roughly. Acceleration may also become noticeably weaker.

Several different faults can produce these symptoms, so it’s important to diagnose the problem rather than immediately replacing parts.

We inspected the Nissan to determine why the engine wasn’t running correctly.

What Causes an Engine to Misfire?

A petrol engine requires the correct combination of fuel, air, compression and ignition for each cylinder to operate properly.

If one of these is missing or incorrect, the affected cylinder may misfire.

Possible causes include:

• worn or faulty spark plugs
• ignition coil problems
• fuel injector faults
• wiring or electrical problems
• incorrect fuel delivery
• vacuum or intake problems
• low engine compression

Because several faults can produce similar symptoms, diagnostic testing can help narrow down the cause.

Faulty Spark Plugs Causing the Nissan Misfire

Our inspection found a problem with the Nissan’s spark plugs.

Spark plugs create the spark required to ignite the air and fuel mixture inside a petrol engine. They operate thousands of times every minute while the engine is running.

As spark plugs wear or develop faults, the quality of the spark can deteriorate.

A faulty plug may prevent one cylinder from firing correctly. This can cause rough running, vibration, reduced power and poor engine performance.

In this Nissan, faulty spark plugs were responsible for the engine not operating correctly on all four cylinders.

Why Spark Plug Condition Matters

Spark plugs are relatively small components, but they play an important role in engine performance.

Worn plugs can increase the voltage required from the ignition system and may contribute to misfires under acceleration or engine load.

Drivers may notice symptoms such as difficult starting, hesitation, reduced performance or an engine warning light.

Following the manufacturer’s recommended servicing schedule can help prevent spark plugs from remaining in service well beyond their intended replacement interval.

Should You Keep Driving With an Engine Misfire?

Continuing to drive a vehicle that is badly misfiring isn’t something we’d recommend unnecessarily.

An engine misfire can make the vehicle difficult to drive and may place additional stress on other components.

Unburned fuel may also enter the exhaust system when a cylinder isn’t firing correctly. In some situations, this can contribute to excessive heat in the catalytic converter.

If the engine begins running very roughly or the engine warning light starts flashing, having the problem investigated is the sensible option.

Diagnosing the Problem at the Vehicle

This Bullsbrook callout demonstrates the value of diagnosing a vehicle where the problem occurs.

The symptoms showed that the Nissan wasn’t running correctly, but that alone didn’t identify which component had caused the fault.

By inspecting the vehicle and checking the ignition system, we identified the faulty spark plugs as the cause.

Finding the actual fault allowed the problem to be addressed without simply guessing which parts required attention.

Roadside Assistance for Engine Problems in Perth

CMM Automotive provides mobile roadside assistance throughout Perth for many unexpected vehicle problems.

A vehicle doesn’t need to stop completely before roadside assistance becomes useful. Severe rough running, engine misfires and loss of power can also make continuing to drive undesirable.

Our mobile service allows us to attend the vehicle and investigate the problem at its location.

For customers requiring breakdown assistance in Perth, identifying the cause can help determine whether the vehicle can be repaired on site or requires further attention.

Nissan Breakdown Assistance in Bullsbrook

The Nissan in Bullsbrook was unable to run correctly on all four cylinders because of faulty spark plugs.

What initially appeared to be a potentially serious engine problem ultimately came down to components within the ignition system.

This is another example of why proper diagnosis matters when a vehicle suddenly begins running differently.

A Holden Astra blown tyre left a customer stranded on the side of the road in Ellenbrook. CMM Automotive attended the vehicle to assess the problem and help determine the safest way to get the Astra back on the road.

The vehicle had suffered a tyre failure while driving. However, the blown tyre wasn’t the only concern we discovered.

Another tyre on the Holden Astra was extremely bald and appeared to be at serious risk of failure.

Holden Astra Stranded With a Blown Tyre

A tyre blowout can happen suddenly and can make a vehicle difficult or unsafe to drive.

When we attended the Holden Astra in Ellenbrook, one tyre had already failed completely.

Before deciding on the next step, we also inspected the condition of the other tyres. This revealed another significant problem.

A second tyre had very little usable tread remaining and required attention.

Second Tyre Was Extremely Bald

Finding the second tyre was important because simply dealing with the tyre that had already failed wouldn’t address the overall safety of the vehicle.

Tyres provide the contact between the vehicle and the road. Their condition affects braking, steering and grip, particularly in wet conditions.

As tyre tread wears away, the tyre becomes less capable of dispersing water from underneath the contact patch.

A severely worn tyre may also have other signs of deterioration that increase the risk of failure.

In this case, the condition of the second tyre meant it also required urgent attention.

Why Bald Tyres Can Be Dangerous

Tyre tread isn’t there simply to determine whether a tyre looks worn.

The grooves in the tread help move water away from the tyre while driving on wet roads. When those grooves become too shallow, the tyre has less ability to maintain contact with the road surface.

This can increase the risk of losing grip in wet conditions.

Tyres should also be inspected for uneven wear, cracking, bulges and visible damage. Abnormal wear can sometimes indicate problems with wheel alignment, steering or suspension components.

Regular tyre checks can help identify these problems before a roadside failure occurs.

What Should You Do if a Tyre Blows While Driving?

A sudden tyre failure can be frightening, particularly at higher speeds.

If a tyre fails while you’re driving, maintain control of the vehicle and avoid making sudden steering movements where possible. Reduce your speed and move the vehicle to a safe location away from traffic when conditions allow.

Once stopped, avoid continuing to drive on a tyre that has completely lost its air pressure.

Driving on a failed tyre can damage the wheel and may make the vehicle harder to control.

If you’re unable to safely deal with the problem yourself, roadside assistance can help assess the situation.

Checking More Than the Failed Tyre

This Ellenbrook callout demonstrates why it’s worth looking beyond the most obvious problem.

The blown tyre was clearly the reason the Holden Astra had stopped. However, inspecting the remaining tyres revealed another issue that could have caused another roadside breakdown.

Checking all four tyres after one suffers a serious failure can reveal whether the problem is isolated or whether other tyres also require attention.

It’s particularly important when tyres are similar in age or have travelled similar distances.

Roadside Assistance for Tyre Problems in Perth

CMM Automotive provides mobile roadside assistance throughout Perth for a range of unexpected vehicle problems.

A roadside breakdown doesn’t always involve an engine that won’t start. Tyre failures, mechanical faults and other problems can also leave a vehicle unable to continue safely.

A Toyota LandCruiser overfilled with oil can develop some alarming symptoms. CMM Automotive recently attended a LandCruiser in Balcatta after the owner accidentally added approximately four litres too much engine oil.

Soon afterwards, the LandCruiser began smoking.

Understandably, the owner became concerned that something serious had gone wrong with the engine. Rather than continuing to drive the vehicle, he contacted CMM Automotive for roadside assistance.

LandCruiser Smoking After an Engine Oil Top-Up

The timing of the problem provided an important clue.

The LandCruiser had started smoking after the owner added engine oil. This made checking the oil level one of the first steps in diagnosing the problem.

Our inspection confirmed that the engine contained considerably more oil than it required.

An extra four litres is a significant overfill. The engine needed the excess oil removed before the vehicle returned to normal operation.

What Happens When You Put Too Much Oil in an Engine?

Engine oil performs several critical jobs. It lubricates moving components, reduces friction and helps protect the engine while it operates.

However, more oil does not mean more protection.

When the oil level becomes excessively high, rotating engine components can come into contact with the oil. This can cause the oil to aerate or foam and may interfere with normal lubrication.

Excess oil can also enter areas where it should not normally be present.

Depending on the engine and the amount of overfill, the vehicle may develop smoke, unusual running conditions or other symptoms.

Why Was the Toyota LandCruiser Smoking?

In this case, the smoking began after the engine oil was significantly overfilled.

Excess oil can make its way through the engine’s ventilation system and into the intake. The engine may then burn some of this oil during operation, which can produce visible exhaust smoke.

A badly overfilled engine can also create excessive crankcase pressure and place additional stress on seals and other components.

That’s why continuing to drive a vehicle with a severely overfilled engine isn’t a good idea.

Correcting the LandCruiser’s Engine Oil Level

CMM Automotive removed the excess engine oil from the Toyota LandCruiser.

We then checked the oil level again to ensure the engine contained the appropriate amount.

Removing the excess oil addressed the immediate cause of the problem and allowed us to assess the vehicle after correcting the oil level.

This Balcatta callout is a good example of why diagnosing what happened immediately before a vehicle developed a fault can provide valuable information.

What Should You Do if You Overfill Your Engine Oil?

If you realise that you’ve added slightly too much oil, check the dipstick and determine how far the level sits above the maximum mark.

A substantial overfill requires more caution.

If the dipstick shows the oil level considerably above the maximum mark, particularly when the vehicle has started smoking or running differently, avoid continuing to drive unnecessarily.

Having the oil level corrected can reduce the risk of further problems.

If you’re unsure how much oil has been added or the vehicle has already developed symptoms, professional assistance can help determine the safest next step.

Roadside Assistance for Unexpected Vehicle Problems

Not every roadside callout involves a flat battery or a vehicle that won’t start.

CMM Automotive provides mobile roadside assistance throughout Perth for many unexpected vehicle problems. This includes situations where a vehicle develops symptoms that make the owner unsure whether it is safe to continue driving.

Our mobile service allows us to inspect the vehicle at its location and determine what has caused the problem.

For customers requiring breakdown assistance in Perth, this can help avoid driving a vehicle when doing so could make the problem worse.

Mobile Roadside Assistance in Balcatta

This Toyota LandCruiser callout demonstrates the advantage of having an experienced mobile mechanic come directly to the vehicle.

The owner knew something was wrong because the LandCruiser had started smoking. By checking what had changed immediately before the symptoms appeared, we quickly identified the excessive engine oil level.

CMM Automotive provides roadside and breakdown assistance for customers throughout Balcatta and surrounding Perth suburbs.

If your vehicle develops an unexpected mechanical problem, contact CMM Automotive on 1800 888 990 for assistance.

Mobile roadside assistance Perth can be particularly useful when a vehicle suddenly refuses to start and the cause isn’t immediately obvious. CMM Automotive recently attended a Hyundai in Brookdale after the owner discovered the vehicle would not start.

At first, the problem appeared to be a straightforward flat battery. However, finding out why a battery has gone flat can be just as important as getting the vehicle started again.

Hyundai Wouldn’t Start in Brookdale

When the owner attempted to start the Hyundai, the battery did not have enough power to crank the engine normally.

There are many reasons why this can happen. The battery itself may be reaching the end of its life, the charging system may have a problem or an electrical component may have continued drawing power while the vehicle was parked.

Rather than simply assuming the battery had failed, we checked the vehicle to determine what had caused the loss of battery power.

Sunvisor Interior Light Left On

During our inspection, we found the cause of the problem.

The interior light built into the Hyundai’s sunvisor had been accidentally left on.

Although an interior light uses considerably less electricity than many other vehicle components, it can continue drawing power for hours while the engine is switched off.

Given enough time, that electrical load can discharge the battery until there is no longer sufficient power available to start the engine.

In this case, the small sunvisor light had been enough to leave the Hyundai unable to start.

Why Can a Small Interior Light Flatten a Car Battery?

A vehicle battery has a limited amount of stored electrical energy.

While the engine is running, the alternator supplies electrical power and recharges the battery. Once the engine is switched off, anything left operating must draw its power directly from the battery.

Interior lights, boot lights and other electrical accessories may appear insignificant. However, if one remains on for an extended period, it can gradually discharge the battery.

The problem can become more noticeable if the battery is older or already has reduced capacity.This is the type of simple fault that mobile roadside assistance Perth can identify quickly at the vehicle’s location.

Getting the Hyundai Started Again

Once we identified the cause of the discharged battery, CMM Automotive got the Hyundai started again.

This Brookdale callout demonstrates why roadside assistance in Perth can involve more than simply connecting a jump starter.

Finding the reason behind a flat battery can help prevent the owner from experiencing exactly the same problem the following day.

In this case, the cause was simple: the owner had accidentally left the Hyundai’s sunvisor interior light on.

Other Causes of a Flat Car Battery

Leaving an interior light on is only one possible reason for a vehicle battery to become discharged.

Other common causes can include:

• an ageing or failing battery
• headlights or parking lights left on
• a boot or glovebox light remaining illuminated
• charging system problems
• electrical accessories drawing power
• leaving the vehicle unused for an extended period

If a battery repeatedly goes flat, CMM Automotive can carry out further testing to identify the cause. We can check the battery, charging system and other electrical components for possible faults.

Mobile Car Air Conditioning Perth recently diagnosed a Toyota with an unusual air conditioning problem. The aircon worked normally when the owner first started driving. However, after about one hour, the system would stop producing cold air.

At first, the symptoms suggested an intermittent air conditioning fault.

CMM Automotive tested the Toyota’s air conditioning system to find the cause. Pressure testing showed no obvious refrigerant leaks. The system also passed its vacuum test.

We then checked the refrigerant level. The Toyota contained very close to the correct amount of R134a refrigerant.

Further diagnosis eventually found something completely different.

The radiator was blocked and the engine temperature would rise after driving. The vehicle then entered a protection or limp mode as the engine began overheating. As part of this protection strategy, the vehicle switched off the air conditioning.

Toyota Aircon Works Then Stops

An air conditioning system that works normally before suddenly stopping can have several possible causes.

An electrical fault may cause intermittent operation. A compressor or control problem can also stop the system from cooling.

Low refrigerant may cause poor performance in some situations.

However, we don’t assume that every air conditioning problem comes from the aircon system itself.

Testing this Toyota demonstrated why that approach matters.

Pressure and Vacuum Testing the Aircon System

We started by checking the Toyota’s air conditioning system.

Pressure testing showed no obvious signs of a refrigerant leak. We also vacuum tested the system, and it passed the test.

We then checked the amount of R134a refrigerant.

The system contained very close to the correct refrigerant charge.

These results gave us important information.

A major refrigerant leak wasn’t causing the air conditioning to stop after an hour. We needed to continue investigating the vehicle.

Why Did the Aircon Stop After an Hour?

The time involved provided an important clue.

The air conditioning worked when the Toyota was first driven. The fault only appeared after the vehicle had operated for an extended period.

Further testing found that the engine cooling system had a problem.

The radiator was blocked.

As the Toyota continued driving, the cooling system struggled to control the engine temperature. Eventually, the engine began to overheat.

The vehicle’s control system responded by entering a protection or limp mode.

This also caused the air conditioning to switch off.

Why Can Overheating Turn Off the Air Conditioning?

A car’s air conditioning compressor places an additional load on the engine.

When engine temperature becomes excessive, some modern vehicles can reduce unnecessary loads to help protect the engine.

Turning off the air conditioning compressor can form part of this strategy.

The driver may notice that the vents suddenly begin blowing warm air. This can make the problem appear to be an air conditioning fault.

In reality, the vehicle may be responding to another problem.

For this Toyota, the underlying issue came from the cooling system rather than a lack of refrigerant.

Blocked Radiator Causing Engine Overheating

A radiator plays a critical role in controlling engine temperature.

Hot coolant flows through the radiator, where airflow helps remove heat before the coolant returns to the engine.

A blockage can reduce the radiator’s ability to transfer heat.

The vehicle may appear normal when first started. However, the engine temperature can increase as driving continues.

This explains why the Toyota’s problem appeared after approximately an hour rather than immediately.

Once temperatures became excessive, the vehicle responded by protecting the engine.

Why an Aircon Regas Wouldn’t Have Fixed This Toyota

This Toyota already contained close to the correct amount of R134a refrigerant.

Adding more gas would not have repaired the problem.

The air conditioning system also passed our pressure and vacuum tests.

The real fault was elsewhere in the vehicle.

This case demonstrates why professional car air conditioning diagnosis in Perth is so important.

If we had focused only on the refrigerant, we could have missed the blocked radiator and the overheating problem.

Aircon Problems Can Sometimes Come From Other Systems

Modern vehicles use electronic control systems that communicate with many components.

Engine temperature, electrical load and other operating conditions can influence air conditioning operation.

This means an aircon complaint isn’t always caused by an aircon component.

The symptoms still matter.

If a customer tells us the air conditioning works for an hour before stopping, that information can help guide our diagnosis.

Finding out when and how a fault occurs can be just as important as testing the system itself.

Our goal is to identify the actual problem rather than simply add refrigerant and hope it fixes the complaint.

Does Your Car Aircon Stop After Driving?

If your air conditioning works when you first start driving but later turns warm, the vehicle needs proper diagnosis.

Don’t automatically assume it needs an aircon regas.

An electrical fault, compressor problem or another vehicle system may affect air conditioning operation.

CMM Automotive can come directly to your location, test the system and investigate the cause.

Frequently Asked Questions

Why does my car aircon work for an hour and then stop?

Several faults can cause this problem. Electrical issues, compressor faults and excessive engine temperature can all affect air conditioning operation.

Can engine overheating cause the aircon to turn off?

Yes. Some vehicles can disable the air conditioning compressor when engine temperatures become excessive. This reduces load and helps protect the engine.

Would an aircon regas fix this problem?

Not in this Toyota. The system already contained close to the correct R134a charge. A blocked radiator and rising engine temperature caused the problem.

Can CMM Automotive diagnose intermittent aircon problems?

Yes. CMM Automotive diagnoses many intermittent air conditioning faults throughout the Perth metropolitan area.

Mobile Car Air Conditioning Perth recently attended a Mitsubishi in Northbridge with an unusual air conditioning problem. The system produced cool air, but it wasn’t getting properly cold. The owner also told us that the air conditioning would sometimes stop working completely.

CMM Automotive carried out a series of tests to find the cause.

Our nitrogen pressure test detected refrigerant leaking from the air conditioning Schrader valves. We replaced both leaking valves and charged the system with the correct amount of R134a refrigerant.

At first, everything appeared to work correctly.

However, we allowed the Mitsubishi to continue running. About 20 minutes later, the vents suddenly started blowing hot air.

Further diagnosis found a second fault. An electrical relay would heat up after operating for some time and then stop working.

Mitsubishi Air Conditioning Not Cold Enough

Air conditioning problems aren’t always straightforward.

The customer’s description can provide important information before testing even begins.

In this case, the Mitsubishi had two symptoms. The air wasn’t getting cold enough, and the system would sometimes stop working.

That second symptom was particularly important.

An air conditioning system that works and then suddenly stops can have an electrical or control problem. However, we still needed to test the entire system.

Nitrogen Testing Found Refrigerant Leaks

CMM Automotive pressure tested the Mitsubishi’s air conditioning system with nitrogen.

The test identified leaks from the Schrader valves.

Schrader valves provide service access to the air conditioning system. Like other seals and components, they can eventually develop leaks.

Even a small leak can allow R134a refrigerant to escape over time.

We replaced both faulty Schrader valves before continuing with the air conditioning service.

Recharging the System With R134a Refrigerant

After repairing the leaks, we charged the Mitsubishi’s air conditioning system with the correct amount of R134a refrigerant.

The system initially operated correctly.

Cold air began coming from the vents, and the repair appeared successful.

However, the owner’s original complaint included an important detail. The air conditioning sometimes stopped working.

For that reason, we didn’t finish our testing as soon as the system began producing cold air.

We allowed the vehicle and air conditioning system to continue running.

That decision helped us find the second problem.

Aircon Suddenly Started Blowing Hot Air

About 20 minutes later, the Mitsubishi’s air conditioning suddenly started blowing hot air.

We now had the intermittent fault happening while we were testing the vehicle.

This allowed us to continue diagnosing the problem.

Further electrical testing identified a faulty relay.

The relay worked when it was cold. However, it became hot after operating for a period of time. Once the relay heated up, it stopped functioning correctly.

The air conditioning then stopped producing cold air.

Why Intermittent Aircon Faults Can Be Difficult to Find

An intermittent fault may not appear when a mechanic first tests the vehicle.

The system might work perfectly for five or ten minutes. The problem may only occur once components reach operating temperature.

This can make diagnosis more difficult.

If we had tested this Mitsubishi for only a short period, we could have missed the faulty relay.

The customer may have driven away with cold air, only for the same problem to return later.

Allowing the system to operate for longer reproduced the owner’s original complaint.

Two Different Air Conditioning Faults

This Mitsubishi had two separate air conditioning problems.

The leaking Schrader valves allowed refrigerant to escape. We needed to repair those leaks and restore the correct R134a charge.

The faulty relay caused a completely different problem.

Once the relay became hot, it stopped working and affected the air conditioning operation.

Repairing only the refrigerant leak would not have solved the customer’s entire complaint.

This is a good example of why professional car air conditioning diagnosis in Perth matters.

Why We Test Before and After Aircon Repairs

CMM Automotive doesn’t simply identify one problem and assume the job is complete.

Testing the system after repairs can reveal other faults.

We check air conditioning performance and vent temperatures. We also make sure the system continues operating correctly.

This becomes especially important when the customer reports an intermittent problem.

The information the owner provides can help us reproduce the fault and identify its cause.

CMM Automotive provides mobile air conditioning diagnosis and repairs in Northbridge and throughout the Perth metropolitan area.

We bring professional air conditioning equipment directly to your home or workplace.

Our services include leak detection, nitrogen pressure testing and system performance checks. We also diagnose compressor and electrical faults.

Our goal is to find the cause rather than simply treat the symptom.

Does Your Car Aircon Work and Then Stop?

If your air conditioning starts cold but later blows warm or hot air, an intermittent fault may be causing the problem.

Don’t automatically assume that the system simply needs more refrigerant.

CMM Automotive provides Mobile Car Air Conditioning Perth services for many common and intermittent aircon faults.

We can test the system, identify the problem and explain the appropriate repair.

Frequently Asked Questions

Why does my car aircon work and then suddenly blow hot air?

Electrical faults, compressor problems and other control issues can cause intermittent air conditioning operation. Proper testing can help identify the cause.

Can Schrader valves leak aircon refrigerant?

Yes. Worn or damaged Schrader valves can allow refrigerant to escape from the air conditioning system.

Why should an aircon system run after repairs?

Running the system allows the technician to check its performance. It can also help reveal faults that only appear after components become hot.

Does CMM Automotive diagnose intermittent aircon faults?

Yes. CMM Automotive diagnoses many electrical, refrigerant and mechanical air conditioning problems throughout Perth.

Mobile Car Air Conditioning Perth recently attended a Volkswagen in Edgewater because the air conditioning vents were not blowing cold air. At first, the symptoms could easily suggest low refrigerant or another common aircon fault.

CMM Automotive tested the system before recommending any repairs.

Our initial vent temperature test confirmed that the air entering the cabin wasn’t cold enough. However, testing under the bonnet showed that the vehicle’s air conditioning system was operating correctly.

The system contained the correct amount of R134a refrigerant and showed no signs of a refrigerant leak.

Further diagnosis found the real problem inside the vehicle. The interior air flaps were not closing off the heater correctly. This allowed hot air to mix with the cold air before it reached the vents.

VW Air Conditioning Blowing Warm Air

Warm air from the vents doesn’t always mean that the refrigeration system has failed.

A vehicle’s air conditioning system has several components working together. The compressor circulates refrigerant through the system. Other components remove heat and help produce cold air.

However, producing cold air is only part of the process.

The vehicle must also control where that air travels and how much heat mixes with it.

This is where the interior HVAC system becomes important.

Testing the Volkswagen Air Conditioning

We started by checking the temperature of the air coming from the VW’s interior vents.

The vent temperature confirmed the customer’s complaint. The air wasn’t getting cold enough.

We then continued testing the air conditioning system under the bonnet.

The refrigeration side of the system was working correctly. It also contained the correct amount of R134a refrigerant.

Our testing found no refrigerant leaks.

This information allowed us to look beyond the usual causes of poor air conditioning performance.

The VW Didn’t Need an Aircon Regas

Many drivers assume that warm air means their vehicle needs an air conditioning regas.

This Volkswagen shows why that isn’t always true.

Adding more refrigerant would not have fixed the problem. The system already contained the correct refrigerant charge.

Adding unnecessary refrigerant can also create further problems.

Instead, we continued diagnosing the system to find out why cold air wasn’t reaching the cabin correctly.

Interior Air Flaps Causing the Problem

Further testing identified a problem with the interior air flaps.

The HVAC system uses internal doors or flaps to control airflow and temperature. These flaps help direct air through different parts of the heater and air conditioning system.

When the driver selects a cold temperature, the system should limit unwanted heat from entering the airflow.

The flaps in this Volkswagen were not closing off the heat correctly.

As a result, warm air mixed with the cold air produced by the air conditioning system. By the time the air reached the dashboard vents, it was no longer cold enough.

Why Aircon Diagnosis Is Important

This VW in Edgewater provides a good example of why proper car air conditioning diagnosis in Perth matters.

The obvious symptom was warm air from the vents.

A quick assumption might have led someone to regas the system. However, a regas would not have solved this fault.

We checked the refrigerant level and system operation first. Those tests showed that the air conditioning components under the bonnet were doing their job.

That allowed us to investigate the interior temperature control system.

Finding the actual cause prevents unnecessary work and expense.

What Are Car Air Conditioning Blend Doors?

Many people call them air flaps, blend doors or temperature doors.

These components sit inside the vehicle’s HVAC housing. They control how air moves through the heating and air conditioning system.

Depending on the vehicle, electric actuators may move these doors when the driver adjusts the temperature controls.

If a flap sticks or fails to move correctly, the system may mix too much heated air with the cold air.

The result can feel exactly like an air conditioning system that isn’t cooling properly.

Aircon Not Cold Doesn’t Always Mean Low Gas

Refrigerant levels are important, but they are only one part of air conditioning diagnosis.

A vehicle can have the correct refrigerant charge and still blow warm air.

Compressor control problems, electrical faults and airflow issues can all affect performance. Interior temperature doors can also cause problems, as we found with this Volkswagen.

Testing helps separate these faults from a genuine refrigerant problem.

That’s why CMM Automotive diagnoses the system before recommending a repair or regas.

CMM Automotive provides mobile car air conditioning diagnosis in Edgewater and across the Perth metropolitan area.

We bring professional diagnostic equipment directly to your home or workplace.

Our services include vent temperature testing, refrigerant leak detection and system performance testing. We also diagnose compressor, electrical and temperature control problems.

Our goal is to find out why the air conditioning isn’t working correctly.

Car Aircon Not Blowing Cold?

If your vehicle’s air conditioning isn’t cold enough, don’t automatically assume that it needs more refrigerant.

The problem may come from another part of the system.

CMM Automotive provides Mobile Car Air Conditioning Perth services for a wide range of aircon faults.

We can test the system, identify the likely cause and explain the appropriate next step.

Frequently Asked Questions

Why is my car aircon warm when it has enough refrigerant?

Several faults can cause this problem. Interior air flaps, electrical controls and other HVAC components can affect the temperature at the vents.

What does an aircon blend door do?

A blend door controls how much heated and cooled air enters the cabin. A faulty door can cause warm air from the vents.

Does warm air always mean my car needs a regas?

No. This Volkswagen had the correct R134a charge and no refrigerant leaks. The problem came from the interior air flaps.

Does CMM Automotive provide mobile aircon diagnosis in Edgewater?

Yes. CMM Automotive provides mobile car air conditioning diagnosis throughout Edgewater and the Perth metropolitan area.

Mobile Car Air Conditioning Perth recently attended a Jeep in Balga with an air conditioning system that was no longer working correctly. The owner had no effective air conditioning and needed the system professionally diagnosed.

CMM Automotive attended the Jeep and carried out several tests at the vehicle’s location.

The system initially passed a vacuum test without showing an obvious problem. However, we continued testing rather than assuming the system was leak-free.

A nitrogen pressure test produced a different result. We used our air conditioning analyser at the interior vents and detected refrigerant coming through the dash area.

This indicated a leak within the air conditioning system behind the dashboard.

Jeep Air Conditioning Not Working

A car air conditioning system can stop cooling for many reasons.

Low refrigerant is a common cause. However, refrigerant doesn’t simply disappear from a sealed system without a reason.

A leak may develop in the condenser, hoses, seals or other air conditioning components. Leaks can also occur within components located behind the dashboard.

Finding these leaks can require more than one type of test.

This Jeep in Balga provided a good example.

Vacuum Testing the Jeep Air Conditioning System

CMM Automotive began by vacuum testing the air conditioning system.

Vacuum testing forms an important part of air conditioning diagnosis and servicing. It can help identify leaks before charging the system with refrigerant.

In this case, the Jeep showed no obvious problem during the vacuum test.

It would have been easy to stop testing at this point.

However, we wanted to make sure the system could also hold pressure correctly.

Nitrogen Pressure Testing Found the Problem

We then pressure tested the Jeep’s air conditioning system with nitrogen.

Nitrogen testing allows us to place the system under positive pressure. This can expose leaks that may not appear during a vacuum test.

The pressure test gave us the information we needed.

We then used an air conditioning refrigerant analyser at the Jeep’s interior vents. The analyser detected refrigerant coming through the dash vents.

This result indicated a refrigerant leak behind the dashboard.

Why Would Refrigerant Come Through the Air Vents?

The evaporator forms part of the vehicle’s air conditioning system and normally sits inside the HVAC housing behind the dashboard.

Air passes across the cold evaporator before travelling through the vents and into the cabin.

A leak in this area can allow traces of refrigerant into the HVAC housing. The blower fan may then carry those traces through the interior vents.

Using suitable electronic detection equipment at the vents can help identify this type of hidden leak.

Without proper testing, finding a leak behind the dashboard can be difficult.

Why Different Aircon Tests Matter

This Jeep demonstrates why CMM Automotive doesn’t rely on a single test when diagnosing every air conditioning problem.

The system appeared acceptable during the vacuum test.

The nitrogen pressure test told us something different.

Pressure and vacuum place different forces on seals and components within the air conditioning system. Some faults may become more noticeable under positive pressure.

Using several diagnostic methods can give us a clearer picture of the system’s condition.

This approach helps us find the actual fault before recommending repairs.

Why We Don’t Just Regas a Leaking Aircon System

Simply adding R134a refrigerant would not repair a leak behind the dashboard.

The air conditioning might begin cooling again after a regas. However, refrigerant could escape again through the existing leak.

The customer would eventually return to the same problem.

This is why CMM Automotive focuses on car air conditioning diagnosis in Perth before recommending a regas or repair.

We want to understand why the system stopped cooling.

Mobile Car Air Conditioning in Balga

CMM Automotive provides mobile air conditioning diagnosis throughout Balga and the Perth metropolitan area.

We bring professional air conditioning equipment directly to your home or workplace.

Our services include performance testing, leak detection, vacuum testing and nitrogen pressure testing. We also diagnose compressor and other air conditioning faults.

Where possible, we identify the cause before recommending repairs.

This can prevent unnecessary parts replacement and repeated regassing.

Car Air Conditioning Not Working?

If your vehicle’s air conditioning has stopped cooling, the system may need more than a simple regas.

A refrigerant leak can occur in several different areas of the system. Some leaks can remain hidden behind the dashboard.

CMM Automotive provides Mobile Car Air Conditioning Perth services for many common air conditioning problems.

We can test the system, explain what we find and recommend the appropriate next step.

Frequently Asked Questions

Can a car aircon system pass a vacuum test and still leak?

Yes. Some leaks may behave differently under vacuum and positive pressure. Further testing can help locate difficult air conditioning leaks.

Why would refrigerant appear at the dashboard vents?

A leak within the HVAC housing can allow traces of refrigerant into the airflow. The blower may then carry those traces through the vents.

Why does CMM Automotive use nitrogen pressure testing?

Nitrogen pressure testing can help locate leaks without unnecessarily adding refrigerant to a faulty system.

Does CMM Automotive provide mobile aircon diagnosis in Balga?

Yes. CMM Automotive provides mobile car air conditioning diagnosis and repairs throughout Balga and the Perth metropolitan area

Mobile Car Air Conditioning Perth recently helped a Hyundai i30 owner whose air conditioning was blowing warm air from every vent. The system was no longer providing the cold air needed for comfortable driving.

CMM Automotive attended the vehicle and carried out a series of air conditioning tests. We first pressure tested the system with nitrogen and found no obvious leaks.

However, further testing told a different story.

The system would not hold a vacuum. Our diagnosis eventually identified a leaking main seal inside the air conditioning compressor. We replaced the faulty compressor to repair the system correctly.

Hyundai i30 Air Conditioning Blowing Warm Air

Warm air from the vents is one of the most common signs of a car air conditioning problem.

Many drivers immediately assume that the system simply needs more refrigerant. However, low refrigerant often indicates another problem.

A leak may allow refrigerant to escape from the system. Other faults can also prevent the air conditioning from cooling correctly.

For this reason, CMM Automotive focuses on diagnosis before recommending repairs.

Simply adding refrigerant without finding the cause may only provide a temporary result.

Nitrogen Pressure Testing the Air Conditioning System

We started our diagnosis by pressure testing the Hyundai’s air conditioning system with nitrogen.

Nitrogen pressure testing can help locate refrigerant leaks. The test allows us to pressurise the system without unnecessarily releasing refrigerant into the atmosphere.

In this case, the system passed the initial nitrogen pressure test. We could not detect an obvious leak during this stage.

However, that did not mean the system was fault-free.

Further testing was required.

The Air Conditioning System Would Not Hold Vacuum

The next step involved vacuum testing the air conditioning system.

A healthy sealed system should maintain the required vacuum during testing. The Hyundai i30 failed this test.

The system would not hold vacuum.

This result gave us another important clue. We continued investigating the system rather than simply regassing the vehicle.

Further diagnosis identified the air conditioning compressor as the source of the problem.

Leaking Air Conditioning Compressor Seal

The main seal inside the Hyundai’s air conditioning compressor was leaking.

This fault explained why the system could behave differently during the nitrogen pressure test and the vacuum test.

Pressure and vacuum place seals under different conditions. A seal may appear to hold under positive pressure but leak when the system operates under vacuum.

This is why using more than one diagnostic method can be important.

If we had relied only on the initial nitrogen test, we could have missed the compressor seal problem.

Replacing the Hyundai i30 Air Conditioning Compressor

Once we identified the leaking compressor seal, we could recommend the correct repair.

CMM Automotive replaced the faulty air conditioning compressor.

Replacing the compressor addressed the actual cause rather than simply treating the warm air symptom.

This Hyundai i30 is a good example of why professional car air conditioning diagnosis in Perth matters.

Air conditioning systems contain several components that must work together correctly. Guessing at the fault can lead to unnecessary parts replacement or repeated regassing.

Testing allows us to make a more informed repair decision.

Why We Don’t Simply Regas Every Warm Aircon System

A regas isn’t automatically the answer when your car’s air conditioning starts blowing warm air.

If refrigerant has escaped, we need to consider why it escaped.

Air conditioning leaks can occur in hoses, condensers, evaporators and seals. Compressors can also develop leaks as they age.

Adding refrigerant to a leaking system doesn’t repair the leak.

The system may cool temporarily before losing refrigerant again.

CMM Automotive tests and diagnoses the system before recommending the most appropriate repair.

Why is my Hyundai i30 air conditioning blowing warm air?

Several problems can cause warm air. These include low refrigerant, leaks, compressor faults and other air conditioning system problems.

Can an aircon system pass a nitrogen test but fail a vacuum test?

Yes. Some seals can behave differently under pressure and vacuum. Using different testing methods can help identify difficult leaks.

Does warm air always mean my car needs an aircon regas?

No. The system may have a leak or another fault. Diagnosis should identify the cause before adding refrigerant.

Can CMM Automotive diagnose car air conditioning at my location?

Yes. CMM Automotive provides mobile car air conditioning diagnosis and repairs throughout the Perth metropolitan area.

Mobile Roadside Assistance Perth recently helped a gentleman in Guildford after his Ford suddenly refused to select a gear. The engine would run, but the transmission could not engage the selected gear correctly.

The customer contacted CMM Automotive for roadside assistance. We travelled directly to the Ford in Guildford and inspected the gear selection problem.

Our inspection found an issue with the transmission linkage. We temporarily secured the linkage to the transmission at the roadside. This allowed the customer to drive the vehicle again and arrange a permanent repair.

Why Would a Ford Suddenly Not Select Gear?

A vehicle that suddenly won’t select a gear can have several possible faults.

Drivers may immediately suspect an internal transmission failure. However, the transmission itself isn’t always the cause.

The gear selector uses a linkage or cable system to transfer the driver’s selection to the transmission. A problem with this system can prevent the transmission from selecting the requested gear.

The driver may move the gear selector, but the transmission may not respond correctly.

This is why diagnosing the problem before assuming the worst can save time and unnecessary expense.

Roadside Transmission Problem in Guildford

CMM Automotive attended the Ford at the customer’s location in Guildford.

We inspected the gear selection system and identified a problem with the transmission linkage. The fault prevented the driver from selecting the required gear correctly.

Rather than immediately arranging a tow truck, we assessed whether we could safely provide a temporary roadside solution.

We temporarily attached the transmission linkage back to the transmission. This restored gear selection and allowed the Ford to drive again.

The temporary measure helped the customer get the vehicle moving. However, the linkage still required a proper permanent repair.

Temporary Roadside Repairs Can Get You Moving

Not every roadside repair provides a permanent solution.

Sometimes a mobile mechanic can safely carry out a temporary repair that allows the driver to move the vehicle. The customer can then arrange the correct repair without requiring an immediate tow.

Safety always comes first.

A temporary repair must suit the fault and the condition of the vehicle. Some breakdowns require towing because driving the vehicle could cause further damage or create a safety risk.

In this case, temporarily securing the Ford’s transmission linkage allowed the vehicle to select gear again.

Does a Gear Selection Problem Mean the Transmission Has Failed?

Not necessarily.

Automatic transmissions contain many mechanical, hydraulic and electronic components. A fault with any of these systems can cause gear selection problems.

However, external components can also cause similar symptoms.

A damaged or disconnected selector linkage may prevent the transmission from receiving the driver’s gear selection. The transmission may still function correctly once the linkage operates as intended.

Proper diagnosis can help identify the actual cause before anyone considers major transmission repairs.

What Should You Do If Your Car Won’t Select Gear?

Don’t force the gear selector if your vehicle suddenly refuses to select a gear.

Forcing the selector may damage other components and make the original problem worse.

Instead, move the vehicle to a safe location if possible. If you can’t safely move it, contact roadside assistance.

An experienced mobile mechanic can inspect the vehicle and determine whether a roadside solution is possible.

This Ford callout shows how mobile roadside assistance in Perth can help with more than batteries, tyres and starting problems.

Mechanical faults can also leave a perfectly running engine unable to move the vehicle.

Mobile Roadside Assistance Perth recently helped a lady in Morley after the fan belt on her vehicle snapped. The breakdown left her unable to continue her journey and in need of roadside help.

CMM Automotive travelled directly to the vehicle in Morley to inspect the problem. We found that the drive belt had snapped. The condition of the belt also highlighted why regular vehicle servicing and maintenance are so important.

A worn belt can often show warning signs before it finally fails.

What Happens When a Fan Belt Snaps?

Many drivers still use the term “fan belt” to describe the engine’s accessory drive belt. Depending on the vehicle, this belt can operate several important components.

These may include the alternator, air conditioning compressor and power steering pump. On some engines, the belt may also drive the water pump.

When the belt snaps, these components can immediately stop working.

The battery warning light may appear because the alternator has stopped charging. Steering may suddenly become much heavier on some vehicles. If the belt drives the water pump, the engine may also begin to overheat.

For these reasons, you should take a broken drive belt seriously.

Roadside Assistance in Morley

The lady contacted CMM Automotive after her vehicle broke down in Morley.

We came directly to her location and inspected the vehicle. We quickly identified the snapped belt as the cause of the immediate problem.

This type of breakdown shows the value of mobile roadside assistance in Perth. An experienced mobile mechanic can inspect the vehicle where the problem occurs.

The driver can then understand what has gone wrong before deciding on the next step.

Can Poor Servicing Lead to Belt Failure?

Regular servicing gives a mechanic an opportunity to inspect belts and other important engine components.

Drive belts naturally deteriorate as they age. Heat, kilometres and constant movement can eventually cause the rubber to harden or crack.

A belt may develop visible cracks, frayed edges or other signs of wear.

Regular inspections can identify many of these warning signs before the belt snaps. A mechanic can then recommend replacement before the vehicle breaks down.

Skipping regular servicing may allow worn components to remain unnoticed for longer.

In this case, the snapped belt provided another reminder of why preventative maintenance matters.

Signs Your Fan Belt May Need Attention

A drive belt doesn’t always fail without warning.

You may hear a squealing or chirping noise from the engine bay. The belt may also show visible cracking or fraying.

A battery warning light can sometimes indicate a belt or charging system problem. Heavy steering may also occur if the belt stops driving a hydraulic power steering pump.

Never ignore an unusual noise from the belt area.

Having the vehicle inspected early may prevent a roadside breakdown later.

Should You Keep Driving With a Broken Fan Belt?

No. If the drive belt has snapped, stop the vehicle in a safe location.

Continuing to drive may create additional problems. This becomes especially important if the belt operates the water pump.

Without coolant circulation, the engine temperature can rise quickly. Severe overheating can cause expensive engine damage.

The alternator may also stop charging the battery after the belt breaks. Eventually, the battery will lose enough power for the engine to stop.

Calling roadside assistance allows a mechanic to assess the situation before you risk further damage.

Regular Servicing Can Prevent Breakdowns

Not every breakdown is preventable. However, regular maintenance can reduce the chance of many common problems.

A vehicle service involves more than changing the engine oil and filter. It also gives a mechanic the chance to inspect components that wear with age and kilometres.

Belts, hoses, fluids, tyres and batteries all deserve regular attention.

Finding a worn component during a service is much better than discovering it after your vehicle stops on the side of the road.

Mobile Roadside Assistance Perth recently helped a customer with a Holden in South Perth after the vehicle suffered a flat tyre. A flat tyre can happen without warning and quickly bring your journey to a stop.

Changing a tyre may sound like a simple job. However, it isn’t always easy or safe to do at the roadside. The driver contacted CMM Automotive for assistance, and we travelled directly to the vehicle in South Perth.

Flat Tyre Assistance in South Perth

A flat tyre can occur for many reasons. A nail or screw may puncture the tyre while driving. Damage from a pothole or road debris can also cause a sudden loss of pressure.

Sometimes a tyre loses air slowly over several days. The driver may only notice the problem when the tyre becomes completely flat.

Whatever the cause, driving on a flat tyre can quickly damage it. It can also damage the wheel and affect the driver’s control of the vehicle.

The safest option is to stop in a suitable location as soon as you notice the problem.

CMM Automotive Attends the Holden

For this roadside callout, CMM Automotive attended the Holden at its location in South Perth.

The customer needed help getting the vehicle mobile again. We came directly to the vehicle, which saved the driver from trying to deal with the flat tyre alone.

This type of callout is a good example of how roadside assistance can help with everyday vehicle problems.

Not every roadside breakdown involves an engine or electrical fault. Sometimes something as simple as a flat tyre can leave a vehicle unable to continue its journey.

Should You Drive on a Flat Tyre?

You should avoid driving any significant distance on a flat tyre.

A tyre relies on air pressure to support the weight of the vehicle. When the tyre loses its pressure, the sidewall can become trapped between the road and the wheel.

Driving in this condition can cause serious tyre damage.

Even a short journey may turn a repairable puncture into a tyre that needs replacement. Continuing to drive may also damage the wheel.

If you notice a flat tyre, find a safe place to stop. Roadside assistance can then help you decide on the next step.

Why Changing a Tyre Isn’t Always Simple

Many drivers have changed a spare tyre before. However, several problems can make the job difficult.

Wheel nuts may be extremely tight. The vehicle’s jack may also be difficult to use, damaged or missing.

Some vehicles don’t even carry a conventional spare wheel.

Roadside conditions can create another problem. Changing a tyre beside moving traffic can put the driver in a dangerous position.

If you don’t feel confident changing the wheel, calling for assistance is often the better choice.

More Than Just Flat Battery Assistance

People often associate roadside assistance with flat batteries and jump starts. In reality, drivers can experience many different problems while travelling.

A flat tyre is one of them.

This Holden callout shows how mobile roadside assistance in Perth can help with unexpected problems that prevent a vehicle from continuing its journey.

CMM Automotive can come directly to your location and assess the situation. We aim to provide a practical solution wherever possible.

Mobile Roadside Assistance Perth recently helped a lady in Greenwood whose Subaru would turn over but would not start. The starter motor was cranking the engine normally. However, the engine would not fire and run.

A car that cranks but refuses to start can have several possible causes. Instead of guessing or replacing parts, the customer contacted CMM Automotive for help.

We travelled to Greenwood to inspect the Subaru and diagnose the problem at the vehicle’s location.

Why Does a Car Turn Over But Not Start?

When you turn the key and hear the engine cranking, the starter motor is doing its job. However, the engine still needs several things before it can run.

The engine needs the correct fuel supply, ignition and air. Modern vehicles also rely on sensors and electronic systems to control the engine.

A fault in any of these areas can prevent the engine from starting.

Possible causes include a fuel supply problem, ignition fault or failed sensor. An electrical problem can also stop the engine from starting.

This is why proper diagnosis matters.

Subaru Won’t Start in Greenwood

When a vehicle won’t start, it can leave the owner in a difficult situation. The car may be sitting at home, at work or in a car park.

In this case, the Subaru was located in Greenwood.

CMM Automotive came directly to the vehicle. This allowed us to begin checking the problem without the owner arranging a tow to a workshop.

A mobile mechanic can often carry out important diagnostic tests where the vehicle has broken down.

A Flat Battery Isn’t Always the Problem

Many people immediately suspect the battery when their car won’t start. However, a battery problem usually affects how quickly the engine cranks.

In this Subaru, the engine was turning over but refusing to start.

That distinction is important.

A strong cranking engine tells a mechanic something different from a vehicle that only clicks when you turn the key.

We can then focus our diagnosis on the systems that allow the engine to start and run.

Diagnosing a Car That Cranks But Won’t Start

Finding the cause requires a logical approach.

We first look at what the vehicle is doing when the driver attempts to start it. We can then check the systems most likely to cause the problem.

Modern diagnostic equipment can also provide valuable information. Fault codes and live vehicle data may help identify an electrical or engine management problem.

However, a fault code doesn’t always mean that a particular component needs replacement. Further testing helps us determine what is actually causing the starting problem.

This approach can reduce unnecessary repairs and parts replacement.

Mobile Roadside Assistance Can Save a Tow

A vehicle that turns over but won’t start doesn’t always need immediate towing.

Mobile diagnosis may identify a problem that we can address at the vehicle’s location. Even when a roadside repair isn’t possible, diagnosis can still provide useful information.

Knowing what has failed can help the owner decide on the next step.

This Subaru callout shows why mobile roadside assistance in Perth can be useful when a vehicle unexpectedly refuses to start.

Instead of guessing at the problem, CMM Automotive can come directly to the vehicle and investigate the cause.
