2021 Audi A6 2.0L Diesel · BK71 AET

This 2021 Audi A6 has maintained a clean MOT history with no defects recorded in either of the two most recent tests, most recently passing on 3 November 2025 at 48,047 miles. The absence of advisories or failures across both tests suggests a stable roadworthiness trend, though the 18-month gap between tests—far exceeding the standard 12-month interval—raises questions about whether the vehicle has been driven regularly or simply passed through routine checks without intermediate maintenance. The most recent test being just six months old places it within the acceptable window for a used-car purchase, though buyers should verify whether the vehicle has been driven consistently since then. The recorded mileage of 48,047 miles over approximately five years equates to around 9,609 miles per annum, which is typical for a vehicle of this age. There are no obvious red flags in the mileage progression, as the gap between tests (35,528 miles in September 2024 to 48,047 miles in November 2025) aligns with steady usage rather than prolonged neglect or rapid wear. However, the lack of intermediate MOTs means there is no record of any potential issues that may have arisen between tests, particularly in high-wear areas like suspension bushes, brake pads, or tyres. Given the clean MOT record, the primary focus for an in-person inspection should be on components that are not directly tested by the MOT but are critical to long-term reliability. The suspension—particularly the condition of coil springs, bushes, and dampers—should be examined for uneven wear or leaks, as these are not routinely checked by the tester. Brake discs and calipers, while not failed in the MOT, should be inspected for excessive thickness variation or binding, which could indicate past neglect. Additionally, the underbody should be scrutinised for corrosion, especially around wheel arches and the sills, as this is a common issue for Audi models of this age. Finally, the exhaust system should be checked for leaks or damage, as emissions-related failures are not always captured in the MOT unless they are visibly severe.
