2006 Audi S4 Avant 4.2L Lpg · DX56 PEO

The vehicle most recently passed its MOT on 12 April 2024, although the overall maintenance trend appears to be declining. While previous tests between 2021 and 2023 were relatively clean, the latest inspection has flagged several emerging issues regarding structural corrosion and rubber component degradation. This shift indicates that the vehicle is now experiencing typical age-related wear that has progressed beyond simple consumable replacement, requiring more focused attention on the chassis and braking system to maintain roadworthiness. With a recorded mileage of 174,763 miles over approximately twenty years, the car has averaged roughly 8,738 miles per year. This is a typical usage profile for a vehicle of this vintage, suggesting it has been used regularly rather than sitting for extended periods. However, such high cumulative mileage places significant stress on the drivetrain, suspension geometry, and engine internals. Prospective buyers should be aware that components such as engine mounts, differential bushings, and the complex Quattro drivetrain will have undergone substantial wear and tear. Particular attention must be paid to the rear subframe mounting prescribed areas, where corrosion has been noted. During a physical inspection, you should examine these areas for any signs of structural thinning or scaling that could lead to a future MOT failure. Additionally, the deterioration of both rear brake hoses is a safety concern; check for visible cracking or perishing of the rubber. On a test drive, listen for knocking or clunking sounds from the front end, which would indicate that the worn upper suspension arm bushes have progressed to a state of excessive movement. Given the vehicle's age and high mileage, it is essential to verify the service history, specifically regarding the timing chain and oil consumption, which are known critical points for this model. Inspect the CV boots for any new splits, as a previous failure in 2020 suggests a vulnerability in the drive shafts. Ensure that the brake discs are not heavily corroded or causing shudder under braking, and verify that the tyres show even wear patterns, as uneven tread would confirm that the suspension bush wear is affecting the vehicle's alignment.
