2015 Audi A6 2.0L Diesel · MR07 MER

The 2015 Audi A6 presents a mixed maintenance picture. The most recent MOT on 16 March 2026 at 99,410 miles passed, but the tester flagged an Offside Front suspension arm ball joint dust cover as severely deteriorated. This is a recurring issue. The car failed on 14 March 2025 at 92,532 miles for the same offside ball joint dust cover, which had deteriorated to the point of no longer preventing dirt ingress. The following year's test on 16 March 2024 at 85,866 miles flagged worn suspension arm pins or bushes on both front corners, though not yet causing excessive movement. The pattern suggests front-end suspension components have been degrading progressively over multiple test cycles, with the offside ball joint boot appearing to have been replaced or repaired after the 2025 failure only to deteriorate again within twelve months. This points to either a recurring defect or a component that was not properly rectified. The mileage accumulation is broadly typical for an eleven-year-old vehicle. Between the March 2024 test at 85,866 miles and the March 2025 test at 92,532 miles, the car covered 6,666 miles in a year. The following year saw a further increase of 6,776 miles to reach 99,410 miles by March 2026. This is a steady, unremarkable rate of use with no sudden jumps or suspicious gaps. The annual mileage sits comfortably around the 9,000-mile mark, consistent with regular daily driving rather than prolonged standing or excessive long-distance use. A buyer should pay close attention to the front suspension during any in-person inspection. The repeated advisories and the 2025 failure centred on the offside lower suspension arm ball joint area warrant a thorough check of the ball joint itself, the arm bushes, and the surrounding track rod ends. Deteriorated dust covers allow grit and moisture into the joint, accelerating wear and potentially leading to play or failure. The 2024 advisory about worn suspension arm pins or bushes on both sides of the front axle further supports the need to inspect all front lower arms, subframe mounting points, and anti-roll bar links for play or perishing. A road test over uneven surfaces will help identify any knocking or vagueness that confirms the wear suggested by the records. Beyond the suspension, the 2023 advisory for a nail in the nearside rear tyre is a minor consumable issue, but it does indicate the previous owner did not always address tyre damage promptly. Check all four tyres for age, uneven wear, and sidewall condition. Given the car's age and the front-end wear pattern, a full four-wheel alignment check and an inspection of the front brake discs and pads for uneven wear would be prudent. The MOT record shows no emissions, braking system, or structural corrosion failures, which is reassuring, but the recurring front suspension faults remain the primary mechanical concern for any prospective purchaser.
