2005 Audi A6 2.5L Diesel · RF55 CWV

The 2005 Audi A6 presents a mixed maintenance picture. The most recent MOT, conducted on 1 March 2023 at 153,099 miles, passed cleanly with zero defects, which is a positive sign. However, this clean bill of health sits just four days after a failure on 27 February 2023 at 153,095 miles, where the tester flagged both front tyres below the 1.6mm legal limit, a missing offside front CV boot, and a severely reduced headlamp output. The fact that these were rectified within days suggests the previous owner addressed immediate failures rather than neglecting them, but the pattern of tyre wear and recurring suspension advisories across multiple years points to a vehicle that has been run hard and maintained reactively rather than preventatively. The mileage record tells an unusual story. Between 8 January 2021 at 131,406 miles and 12 January 2022 at 140,744 miles, the car covered roughly 9,300 miles in twelve months. Then, between 13 January 2022 and 1 March 2023, it accumulated approximately 12,350 miles. Yet from 1 March 2023 to today, 16 June 2026, the recorded mileage has not moved at all, remaining frozen at 153,099 miles. This three-year gap with no MOT activity and zero recorded mileage is significant. The car may have been laid up, exported, or simply left unused. A long stationary period raises its own concerns, including deteriorated rubber components, stale fuel, brake seizure, and fluid degradation, none of which a single clean MOT can confirm have been addressed. The recurring theme across the 2021 and 2022 tests is suspension wear. In January 2022, advisories were recorded for worn suspension arm pins or bushes on all four corners, both front and rear, though none had yet reached the point of excessive movement. These advisories appeared on both the failed and passed tests that year, indicating the wear was present but marginal. A prospective buyer should have the front and rear suspension inspected thoroughly, paying close attention to the lower arm bushes, track rod ends, and anti-roll bar links, as these components deteriorate with age regardless of mileage. The CV boot failure on the nearside front in January 2022 and the offside front in February 2023 suggests the gaiters have been vulnerable to replacement or may have been done cheaply. Check for play in the driveshafts and inspect the boots for fresh splits or grease contamination. The February 2023 failure for both front tyres below the legal limit, combined with advisories for edge wear noted in January 2021, indicates the car has a persistent issue with front tyre wear, possibly from misaligned tracking, worn suspension geometry, or aggressive driving. The headlamp output issue flagged in the same failure could point to lens haziness or a failed bulb, but given the car's age, degraded headlamp reflectors or a wiring fault should not be ruled out. A buyer should verify the headlamp aim and lens condition, test all lighting functions, and check the tyre sizes and pressures against specification. Given the three-year dormancy, a full fluid change, brake inspection for seized calipers or corroded discs, and a thorough underbody check for corrosion are essential before any purchase decision.
