2009 Audi A6 2.0L Diesel · SA59 FDM

The vehicle most recently passed its MOT in October 2025, though it carries a cautionary advisory regarding rear axle corrosion. When reviewing the broader history, the maintenance trend is concerning, as the vehicle has transitioned from minor wear and tear issues to significant structural failures. The October 2024 failure was particularly severe, involving a fractured rear coil spring and a compromised front sub-frame that lacked necessary rigidity. While these were rectified to achieve a pass, the persistent appearance of corrosion across different chassis components suggests a deteriorating structural condition that requires close monitoring. With a recorded mileage of 174,666 miles over approximately seventeen years, the vehicle has averaged roughly 10,274 miles per year. This is a typical usage profile for an executive saloon, indicating it has been used regularly rather than suffering from the degradation associated with long periods of standing. However, this absolute mileage necessitates a critical evaluation of high-wear components. The drivetrain, engine mounts, and suspension bushings will have undergone significant stress, and the buyer should expect the vehicle to exhibit more mechanical noise and less precision in handling than a lower-mileage example. Prospective buyers must prioritise a thorough inspection of the vehicle's underside. Given the history of sub-frame failure and the current advisory for rear axle corrosion, there is a clear risk of systemic rust. You should specifically examine the area near the rear spring mounts and the fuel tank for signs of advanced oxidation or flaking metal. During a test drive, listen for metallic clunks or knocks over uneven surfaces, which could indicate that the previously noted suspension issues or anti-roll bar wear are recurring. Check the steering for any excessive play or vibration, which often accompanies high-mileage wear on suspension arm ball joints. Attention should also be paid to the braking system and tyre condition. Previous records indicate imbalanced rear braking and perishing tyre sidewalls, so check for any shuddering under braking or a tendency for the car to pull to one side. Inspect all four tyres for fine cracking or uneven edge wear, which may suggest misalignment or failing dampers. Finally, given the high mileage, verify the service history for critical interval maintenance, specifically the timing belt and water pump replacements, as well as automatic transmission fluid changes, to ensure the engine and gearbox remain reliable.
