2015 Audi A3 2.0L Diesel · MW15 PKO

The 2015 Audi A3’s most recent MOT test on 19 December 2025 at 85,683 miles passed without defects, indicating a clean record for the past six months. However, the preceding failure in December 2024 at 76,981 miles—just 263 miles after the previous pass—reveals a pattern of serious mechanical issues that were not fully resolved before retesting. The recurring suspension faults (near-side rear shock leak, coil spring corrosion) and the nail in the near-side rear tyre suggest either deferred repairs or repeated neglect. While the vehicle cleared its last test, the 2024 failure highlights unresolved structural risks, particularly in the rear suspension and wheel integrity. Mileage progression shows an average of 7,789 miles annually, which aligns with typical usage for a vehicle of this age. The gap between the 2022 and 2023 tests (7,352 miles in a year) is slightly higher than the subsequent intervals, but no extreme spikes or prolonged inactivity are evident. The 2024 failure occurred after only 263 miles since the previous pass, a red flag for either rushed repairs or a lack of proper maintenance oversight. The most recent 8,441 miles since the last MOT (December 2025) is within an acceptable range, but the history before that demonstrates inconsistent attention to critical components. A buyer should prioritise a thorough inspection of the rear suspension, particularly the near-side components, given the documented fluid leak in the shock absorber and corrosion on both coil springs during the 2024 failure. The nail in the near-side rear tyre at that time indicates past wheel integrity issues, so all tyres should be examined for hidden damage or uneven wear. Front brake pads and discs, though noted as worn in 2024, were not flagged in the latest pass, but their condition should still be verified—thin pads or glazed discs could reappear. The under-tray obscuring components in multiple tests suggests either poor vehicle preparation for inspection or a lack of transparency about modifications. Structural corrosion, especially around the rear springs, warrants closer scrutiny, as does the overall integrity of the wheel arches and subframe.
