2010 Audi A4 2.0L Diesel · L300 ACR

The 2010 Audi A4’s most recent MOT tests, conducted between June 2025 and June 2026, reveal a concerning pattern of repeated failures despite identical mileage readings. The vehicle passed its 2024 and 2023 tests without defects, yet the three consecutive failures in early 2025—all at approximately 132,000 miles—suggest a mechanical issue either unresolved or recurring. The lack of recorded defects in any of these tests implies the failures were likely due to administrative errors or minor procedural oversights rather than critical faults, but the clustering of tests raises questions about whether the vehicle was subjected to repeated diagnostic checks for the same underlying problem. Without specific fault codes or advisory notes, the trend remains ambiguous, but the abrupt shift from consistent passes to repeated failures warrants further scrutiny. The recorded mileage progression of roughly 8,262 miles per year aligns with typical usage for a vehicle of this age, though the static mileage between June 2023 and June 2025—just 3,114 miles over two years—stands out as unusually low. This suggests prolonged periods of inactivity, which could accelerate wear on components like suspension bushes, coil springs, and brake calipers due to lack of movement. The sudden spike to 132,000 miles by June 2025, followed by no further mileage accumulation until the present, may indicate either a change in ownership or a return to active use after storage. Such fluctuations can exacerbate issues like binding calipers or corroded wheel bearings, which are more likely to develop when a vehicle remains stationary for extended periods. Given the repeated MOT failures and the vehicle’s age, a buyer should prioritise an inspection of the braking system, particularly the rear calipers and discs, as binding or uneven wear is a common issue in older Audi models. The suspension should be thoroughly checked for worn or perished bushes, as these are prone to failure after prolonged periods of inactivity. Structural corrosion, particularly around the wheel arches, sills, and subframe, is another critical area—common in vehicles with high mileage and variable usage patterns. The exhaust system should also be examined for leaks or excessive rust, as these can contribute to failed emissions tests. While the MOT history lacks specific fault details, these components are the most likely candidates for hidden deterioration.
