2002 Audi A8 4.2L Petrol · S8 XPS

The vehicle remains roadworthy, but the maintenance history indicates a trend of persistent structural degradation and reactive repairs. The most recent test on January 31 2026 at 150,360 miles passed despite the continued presence of corrosion on the front sub-frame. This structural issue has appeared in every recorded test dating back to at least September 2022, suggesting that while the rust has not yet reached a critical failure point, it is an advancing condition that remains unaddressed. At 150,360 miles over 24 years, the car has averaged approximately 6,265 miles per year, which is consistent with low-to-moderate annual usage. However, the data shows a significant gap in mileage between September 2022 and October 2023, where only 1,810 miles were covered in thirteen months. The subsequent interval of 1,150 miles over the following two years indicates very low recent use. This low mileage may explain why consumable items like tyres are only being replaced when absolutely necessary to avoid MOT failure. A buyer must prioritise a rigorous physical inspection of the front sub-frame and mounting points to ensure the corrosion does not compromise structural integrity moving forward. The tester flagged the same sub-frame issues across three consecutive years, which marks this as a known long-term mechanical concern. Furthermore, the failure in October 2023 due to a loose offside front road wheel fixing suggests a lapse in basic safety checks during maintenance, necessitating a thorough check of all wheel bolts and suspension components. The previous excessive carbon monoxide reading in September 2022 also warrants an engine health check to ensure the combustion system is operating efficiently.
