2009 Audi A6 2.0L Diesel · SA02 ANA

The vehicle remains legally roadworthy but the maintenance history reveals a trend of reactive rather than preventative care. While the most recent test in December 2025 at 248,012 miles identified only thin rear brake pads and a non-excessive oil leak, previous years show a persistent pattern of deferred maintenance. The mechanical state appears stable in terms of passing the test, but the frequency of advisories suggests that components are only addressed when they reach the point of failure or near-legal limits. At 17 years old, the recorded 248,012 miles represent high annual usage, averaging approximately 14,600 miles per year. The data shows consistent, heavy use, with a 21,500-mile jump between December 2023 and December 2024, and another 11,501 miles following that. This high mileage puts significant strain on the drivetrain and suspension components, which is reflected in the recurring failures of CV boots and suspension bushes across the five-year period. A buyer must conduct a thorough physical inspection of the structural integrity and lower suspension. The December 2024 test flagged extensive corrosion on the rear sub-frame, inner suspension mountings, and spring mountings. While the tester noted these were not yet weakened, the presence of rust in these critical areas is a long-term risk for the chassis. Additionally, the recurring deterioration of front drive shaft CV boots in both 2023 and 2024 indicates that rubber components are failing due to age and high mileage. The braking system also shows a history of neglect, with rear pads flagged thin in 2023 and 2025, and pitted or scored discs noted in 2022 and 2024. Consistent advisories regarding tyres worn to the legal limit across every test suggest the owner frequently delays replacing consumables until they are necessary. The oil leak noted in the 2025 test should be monitored to ensure it does not escalate into a significant engine failure given the high-mileage context of the vehicle.
