2017 Audi A6 2.0L Diesel · YK67 YOY

The 2017 Audi A6’s most recent MOT test on 2025-06-10 resulted in a pass, though it was immediately followed by a failure on the same day—an anomaly that suggests either a procedural error or a last-minute inspection oversight rather than a mechanical trend. The preceding tests from 2024-06-25 and 2023-06-19 both passed without recorded defects, indicating a stable roadworthiness pattern over the past three years. The lack of advisories or recurring faults in the official record implies no obvious structural or mechanical degradation, but the double-test in 2025 warrants scrutiny of whether the vehicle was driven between inspections or if the failure was due to a minor oversight rather than a persistent issue. The vehicle’s mileage of 64,631 miles over nine years equates to approximately 7,181 miles annually, which is typical for its age. There are no visible gaps in service intervals or abrupt spikes in mileage between tests, suggesting consistent use rather than neglect or extended periods of inactivity. The most notable irregularity is the double MOT in 2025, which could imply either a rushed sale or a temporary issue resolved before the second attempt. Without additional service records, it’s impossible to confirm whether scheduled maintenance—such as suspension servicing or brake fluid changes—has been adhered to, but the mileage pattern does not raise immediate red flags for excessive wear. A buyer should prioritise an independent inspection of the suspension components, particularly the rear axle, given the 2025 failure occurred on the same day as a pass—potentially indicating a late-stage issue with rear wheel bearings, binding calipers, or worn coil springs. The absence of advisories in prior tests makes it difficult to pinpoint a specific trend, but the Audi A6’s age and mileage suggest attention to brake pads, discs, and rotor thickness, as well as the integrity of the exhaust system for potential leaks or corrosion. Structural checks for rust around wheel arches, sills, and the subframe are also advisable, especially if the vehicle has been exposed to salted roads or poor parking conditions. Given the lack of recorded faults, the risk appears low, but a thorough pre-purchase inspection remains essential to verify hidden wear.
