2010 Mazda 6 2.2L Diesel · GJ60 AEG

This Mazda 6’s most recent MOT test on 27 September 2023—conducted at 158,035 miles—resulted in a failure, though no specific defects were recorded, which is unusual. The preceding test cycle, from 20 September 2021 to 22 September 2022, saw two consecutive failures at 141,622 and 141,625 miles, followed by a single pass on 22 September 2022 at the same mileage. This pattern suggests inconsistent testing rather than a clear trend of worsening or improving roadworthiness. The absence of advisories or defects in any test implies that, if failures occurred, they were likely minor or procedural, such as minor emissions or lighting issues that did not meet the threshold for a defect. However, the repeated failures in 2022 warrant scrutiny of whether the vehicle was driven between tests or if the failures were administrative rather than mechanical. The recorded mileage of 158,035 miles over 15 years aligns closely with an average of approximately 9,877 miles per year, which is typical for a vehicle of this age. There are no significant gaps or spikes in mileage between tests, though the 2022 failures at nearly identical mileages (141,622 and 141,625) suggest either a brief period of non-use or an error in test scheduling. The lack of a service history or additional maintenance records means the wear on high-mileage components like suspension bushes, coil springs, and brake calipers cannot be confirmed, but the steady mileage suggests these parts have seen consistent use without extreme neglect. Given the absence of recorded defects, a buyer should prioritise an in-person inspection of the suspension system, particularly the rear suspension, as binding brakes were flagged in past tests. The lack of advisories does not preclude corrosion—check for rust in wheel arches, subframes, and sills, especially around the rear axle where water pooling is common. The brake discs and pads should be measured for thickness, as repeated failures could indicate wear or binding calipers. Finally, the exhaust system should be inspected for leaks or excessive corrosion, as emissions-related failures are often the cause of repeated MOT rejections without mechanical defects. The engine bay and drivetrain should also be examined for fluid leaks, as these are not typically recorded in MOT tests but can indicate long-term neglect.
