2006 Audi A6 2.0L Diesel · SM56 FLB

The vehicle remains roadworthy but the maintenance history indicates a worsening trend regarding mechanical wear and structural integrity. While the car passed the February 2026 test at 209,684 miles, the tester identified an engine oil leak and underbody corrosion. The presence of a nearside rear tyre worn to the legal limit in this recent test mirrors a failure from February 2025 regarding an offside front tyre, suggesting that basic consumable upkeep and alignment-related wear are not being addressed proactively. At 209,684 miles, this Audi has followed a consistent usage pattern of approximately 10,500 miles per year over its twenty-year lifespan. The data shows steady mileage accumulation, with roughly 14,000 miles covered between the January 2024 and February 2025, and another 13,000 miles leading up to the most recent test. This high mileage places significant stress on the chassis and drivetrain components, which is reflected in the increasing frequency of suspension-related defects. A buyer must prioritise a physical inspection of the structural condition of the rear subframe and mounting points, as the 2024 test already flagged corrosion in these areas. The progression from minor subframe corrosion to general underbody corrosion by 2026 suggests that oxidation is accelerating. Furthermore, the history shows a pattern of suspension failure, including worn coil springs, control arm bushes, and damaged track rod end covers. The buyer should verify if the noted coil springs and shock absorbers have been replaced and must investigate the source of the engine oil leak noted in the latest record to ensure it does not indicate a catastrophic seal failure.
