2009 Audi A8 3.0L Diesel · J66 VAG

The most recent MOT test for this 2009 Audi A8 was conducted on 2025-11-10 and resulted in a clean pass, indicating no defects were recorded. Despite the earlier failures and advisories in the past six years, the vehicle’s maintenance history shows a notable improvement in stability, with only minor advisories noted since 2023. The absence of repeated major failures or persistent issues in the most recent tests suggests that the vehicle has either undergone corrective maintenance or that the underlying problems have been mitigated, though the suspension advisories from 2023 remain a concern that warrants ongoing attention. The vehicle’s recorded mileage of 134,254 miles over approximately 17 years represents an average annual usage of around 7,897 miles, which is consistent with typical driving patterns for its age. This rate of mileage accumulation indicates moderate to heavy usage, particularly given that the vehicle was last tested in 2023 after accumulating roughly 11,000 miles in the preceding two years. Such usage levels can accelerate wear on critical components like suspension bushings, tyres, brakes, and drivetrain elements, which is reflected in the advisories observed in the MOT history. The significant gap between the 2022 failure and the 2023 test—where advisories were noted—suggests that the vehicle may have been driven more heavily during that period, potentially exacerbating wear on suspension and tyre components. Prior to purchasing this A8, the buyer should conduct a thorough inspection of the suspension system, focusing on the front lower and upper arms for signs of excessive play, corrosion, or bush wear. During a test drive, listen for unusual clunking noises from the front suspension, particularly when navigating bumps or corners, as this may indicate worn or failing suspension components. Additionally, check for uneven tyre wear patterns, which could signal misalignment, steering issues, or suspension problems. The tyre advisories from previous MOTs—particularly the nearside front inner tyre wear close to the legal limit—highlight the need for a closer inspection of tyre condition, including checking for sidewall cracking or perishing, which can compromise safety and structural integrity over time. For fluid systems, the buyer should verify the condition of the engine oil, transmission fluid, and brake fluids, as these can degrade over time even without significant mileage. Given the vehicle’s age and usage, the engine oil should be checked for contamination or sludge buildup, and the transmission fluid should be assessed for colour and viscosity changes. Brake systems should be inspected for signs of corrosion on brake discs or binding calipers, which can occur when the vehicle stands for prolonged periods. A thorough check of the exhaust system for leaks, corrosion, or structural damage is also advisable, as the 2022 MIL failure may have been related to an emissions-related issue that could recur. Finally, the battery should be tested for voltage and overall health, as older vehicles are more susceptible to failing due to age alone. If possible, verify service book stamps for scheduled maintenance such as timing belt replacement, which is critical for a 2009 A8 and often overlooked in used vehicle histories.
