2015 Audi A6 2.0L Diesel · MT65 BXK

Recurring suspension component wear and historical tyre tread depth failures define the mechanical profile of this Audi A6. While the most recent test on 18 September 2025 resulted in a pass with no defects recorded, the preceding two years show a consistent pattern of advisories regarding front suspension arm bushes and tyre wear. The vehicle has also experienced two dangerous failure events, specifically in 2020 and 2022, due to multiple tyres falling below the legal 1.6mm tread depth limit. This history indicates a trend of components reaching the end of their service life in clusters, though the absence of defects in the 2025 inspection suggests these specific issues may have been addressed or have not yet recurred. The vehicle has covered 117,483 miles over its eleven-year lifespan, which equates to an average annual usage of approximately 10,680 miles. This represents a typical mileage accumulation rate for a vehicle of this age and class. Such steady usage suggests the mechanical components, including the drivetrain and suspension, have been subjected to regular, consistent loading rather than the extremes of very high motorway mileage or the potential issues associated with long-term stationary periods. This consistent mileage pattern aligns with the gradual degradation seen in the advisory records for consumables like brake pads, discs, and suspension bushes. Prospective buyers should pay close attention to the front suspension geometry and steering response during a test drive. The MOT history repeatedly flags wear in the front lower suspension arm pins or bushes, specifically on both the nearside and offside. On the road, this can manifest as audible knocking or clunking sounds when traversing uneven surfaces or speed bumps, as well as a potential feeling of looseness or wandering in the steering at higher speeds. Given that these advisories appeared in both 2023 and 2024, it is essential to verify if the bushes have been replaced or if the wear is progressing. Attention should also be directed toward the braking system and tyre condition. Although the 2025 record is clear, previous tests highlighted thinning brake pads and pitted or scored front brake discs. During a test drive, listen for any squealing or grinding noises during deceleration and feel for any pedal judder or vibrations through the foot pedal, which can indicate disc irregularities. Furthermore, because the vehicle has a history of dangerous tyre failures, a physical inspection of the current tyre tread depth and checking for uneven wear on the inner or outer edges is necessary to ensure the current set is not nearing the legal limit or suffering from alignment issues.
