Booking a pre-purchase vehicle inspection Perth is the single smartest step you can take before buying a used car. This week, our mobile mechanic carried out a thorough inspection on a 2015 Holden Colorado in Cannington — and the findings were a clear reminder of why skipping an inspection can be a costly mistake.
What Our Mobile Car Inspection Perth Team Found
Our mobile car inspection Perth team completed a comprehensive check across all major vehicle systems. Here is a summary of the key findings.
Cabin and Interior Issues
Inside the cabin, our inspector identified an unexplained hole in the dashboard — a strong indicator of prior modifications or damage. Additionally, the rear wiper blades were not operating correctly, and the air conditioning system was completely non-functional.
ECU Fault Codes
A diagnostic scan of the ECU revealed several fault codes, including an air conditioning pressure sensor circuit fault and multiple immobilizer-related codes. These codes can point to anything from minor sensor failures to more serious security system concerns — issues that may affect the vehicle’s reliability and insurability.
Under the Bonnet
Under the bonnet, the battery tested at only 449 cranking amps — below the performance threshold expected for a diesel 4WD of this size. Furthermore, the transmission oil was heavily contaminated, indicating the owner had not serviced the fluid in some time. As a result, this could lead to costly transmission repairs if left unaddressed.
Brakes, Lights, and Roadworthy Concerns
On the braking side, the front brakes had approximately 70% remaining and the rears sat at 50–60%, so there is still some useful life left in the pads. However, the right-hand front indicator was non-operational — a roadworthy concern that requires rectification before the vehicle WA Transport can legally transfer the vehicle in Western Australia.
Road Test Result
The road test returned a positive result. Our inspector recorded no major concerns during normal operating conditions, which is encouraging given the other findings
