2007 Audi A6 3.0L Diesel · KP57 HAL

The vehicle most recently passed its MOT on 14 October 2025, although this followed a failure on 3 October 2025. The overall maintenance trend appears reactive rather than proactive, as the vehicle has frequently failed on basic electrical items and critical wear components like brake discs before passing. While the car is currently roadworthy, the pattern of failures suggests a maintenance approach focused on minimum compliance for the annual test rather than a comprehensive preventative service regime. At 103,075 miles over nineteen years, the vehicle has averaged approximately 5,425 miles per year, which is significantly lower than the UK national average for an executive saloon of this age. While low mileage generally suggests less mechanical wear on the engine and drivetrain, it often introduces specific risks associated with periods of standing. Low annual usage can lead to the degradation of rubber components, the accumulation of moisture in the braking system, and the potential for battery health to decline due to infrequent charging cycles. Prospective buyers should pay close attention to the braking system, as the MOT history shows a recurring theme of worn and pitted discs across both the front and rear axles. During a test drive, feel for any brake shudder or pulsation through the pedal, which would indicate warped discs, and listen for grinding noises that suggest the pads are depleted. Particular attention must be paid to the front tyres; the 2025 advisory regarding inner edge wear strongly suggests a misalignment of the front tracking or worn suspension bushes. Check for uneven tread depth across the tyre width and listen for clunks or knocks from the front end when traversing uneven road surfaces. Given the vehicle age and low usage, a physical inspection should focus on calendar based degradation. Inspect the tyre sidewalls for fine cracking or perishing, as rubber hardens over time regardless of tread depth. Check the brake calipers for binding and the discs for surface corrosion, which is common in cars that spend long periods stationary. It is essential to verify the service history to ensure that engine oil and other critical fluids have been changed based on time intervals rather than mileage alone, as old oil can lead to sludge build up and internal engine wear. Finally, test the 12V battery cranking strength to ensure it has not been compromised by inactivity.
