2005 Audi A6 1.9L Diesel · LS05 WCC

The 2005 Audi A6 presents a mixed roadworthiness picture, with the maintenance trend showing signs of escalating wear rather than stabilization. In the most recent MOT test on July 29 2025 at 133,118 miles, the vehicle ultimately passed after initially failing for a non-functioning nearside position lamp, alongside recurring advisories for a minor engine oil leak and slightly defective headlamp lenses. While the initial failure was rectified promptly, the underlying pattern reveals an aging executive saloon requiring constant mechanical intervention to remain on the road. Accumulating 133,118 miles over its twenty-one years translates to an average of roughly 6,339 miles annually, which sits comfortably within typical parameters for this vehicle class. The mileage accumulation has remained remarkably consistent across the inspection history, moving steadily from 84,208 miles in June 2016 to the current reading without experiencing any prolonged periods of storage or erratic spikes in usage. This steady progression implies the car has seen regular, moderate employment rather than sitting idle, which generally helps prevent seizure-related faults but accelerates routine consumable fatigue. A prospective buyer must pay close attention to several recurring mechanical weak points highlighted throughout the history. Front suspension arm bushes and coil springs feature repeatedly as advisories or minor defects, starting from the perishing top arm bushes noted in June 2017 through to corroded rear coil springs and deteriorated constant velocity gaiters logged in July 2024. Furthermore, constant velocity boots failed on both sides in 2024 and previously in 2018 and 2019, suggesting the front drivetrain seals degrade faster than average. Inspection of the front wishbone assemblies, CV boot integrity, brake lines, and underbody corrosion on the rear axle and suspension components is essential before purchase.
