2010 Audi A6 2.7L Diesel · KT10 WCJ

The Audi A6 presents a stable and broadly improving mechanical picture heading into mid-2026. The most recent test on 3 July 2025 at 115,099 miles passed cleanly, with only a minor rear registration plate lamp defect noted on the previous day’s failure — a fault that was clearly rectified within 24 hours. This pattern of a swift retest and immediate pass suggests attentive, if not meticulous, ownership in the recent past. The vehicle has not failed an MOT since July 2024, and the 2023 test at 104,359 miles recorded zero defects at all, reinforcing a trend of resolving rather than accumulating issues. The mileage progression tells a consistent story. Between July 2023 and July 2024, the car covered 6,049 miles, and from July 2024 to July 2025 it added 4,691 miles — a slight reduction in annual use but still well within the typical range for a 16-year-old vehicle averaging roughly 7,194 miles per year. There are no alarming gaps or sudden jumps in the odometer that would suggest long periods of disuse or tampering. The mileage sits at 115,099 as of the July 2025 test, and given that date is now nearly 11 months behind today’s date of 18 June 2026, the true current mileage will be somewhat higher — likely in the region of 119,000 to 120,000 miles assuming normal use. A buyer should verify the current odometer reading against service records to confirm continuity. The recurring advisories and failures point to two areas worth close physical inspection. Front suspension arm bushes appeared worn on both sides in the July 2024 test, flagged as not yet causing excessive movement but clearly deteriorating. These components age progressively, and at nearly two years since that advisory, a buyer should check for knocking over rough surfaces, uneven inner tyre wear, and play in the front end. The rear brake discs were also noted as worn and pitted in the same test — again, not seriously weakened at the time, but corrosion and scoring on braking surfaces tend to worsen with age and mileage, particularly on a car that may see less aggressive use at this stage of its life. The July 2025 failure added a missing front lower undertray and a detached anti-roll bar bush or pin, both of which were evidently fixed before the pass the following day. A missing undertray on an A6 is not merely cosmetic; it exposes the engine bay, subframe, and steering components to road spray and grit, accelerating corrosion on a vehicle now over 16 years old. A buyer should inspect the front subframe, inner wing lower edges, and suspension mounting points for rust — particularly given the car’s age. The repeated rear lamp issues are trivial in isolation but hint at a possible wiring or ground fault in the tail light cluster that may resurface. Overall, the record reflects a car that has been kept on top of rather than neglected, but its age demands a thorough underbody and suspension inspection before purchase.
