2015 Audi Q3 2.0L Diesel · C7 AHF

The most recent MOT history reveals a critical failure in May 2026, where the offside rear coil spring fractured despite a clean record in prior tests. This marks the first and only defect in the vehicle’s documented history, but the immediate back-to-back tests at 83,167 and 83,168 miles—both within a single day—highlight an urgent structural issue that was not addressed before the final pass. The preceding four tests, spanning over two years, showed no faults, suggesting the failure was sudden rather than a gradual deterioration. However, the lack of a rectification record between the failure and pass raises concerns about whether the defect was genuinely resolved or merely overlooked. The mileage progression of 83,168 miles over eleven years averages approximately 7,560 miles annually, which is typical for a vehicle of this age and model. There are no significant gaps or abrupt spikes in usage, though the final 8,600 miles were covered in just over a year, from the May 2025 test to the latest failure. This suggests consistent but not excessive driving, though the rapid accumulation in the last period could indicate deferred maintenance or a change in usage patterns. The absence of advisories or partial passes in earlier tests further implies the vehicle was either well-maintained or that minor issues were not flagged by the tester. Given the fractured offside rear coil spring, a buyer must prioritise an immediate inspection of the suspension system, particularly the remaining rear coil springs and associated bushes, for signs of fatigue or corrosion. The binding calipers or uneven brake wear mentioned in the failure could also persist, so the rear brake system—including discs, pads, and calliper guides—should be thoroughly checked for binding, excessive wear, or fluid leaks. Structural integrity is paramount; the chassis rails, subframe, and wheel arches should be examined for corrosion or damage, especially around the rear suspension mounts. Given the sudden nature of the failure, a professional assessment of the spring’s replacement quality and the alignment of the rear axle is essential to prevent recurrence.
