2002 Audi S8 4.2L Petrol · MM51 XNE

The vehicle is currently roadworthy, but the MOT history indicates a significant decline in mechanical condition following a period of stability. While the car passed its test in June 2025 at 139,516 miles, this followed two consecutive failures in April of the same year. The trend shows a transition from a clean record in 2022 to a series of fluid leaks, emissions failures, and structural corrosion, suggesting the vehicle has suffered from neglect or accelerated component degradation during its more recent usage. At 24 years old, the recorded mileage of 139,516 miles is notably low, averaging approximately 5,800 miles per year. However, there is a conspicuous gap in testing between September 2022 and April 2025, during which the vehicle covered only 5,344 miles. This low annual usage often correlates with the appearance of the faults noted in the 2025 records, such as brake disc corrosion and corroded springs, which deteriorate when a vehicle sits stationary for long periods, alongside the carbon monoxide emission failures. A physical inspection must focus heavily on the recurring leaks and suspension issues identified in the 2025 tests. The tester flagged both an oil leak and a weeping power steering hose, which require a thorough check to determine if they are minor seepage or escalating failures. The presence of corrosion on both rear coil springs is a structural concern; while they passed the latest test, corroded springs are prone to sudden failure. Furthermore, the buyer should verify the coolant system for pressure leaks, as this was recorded in April but not necessarily fully resolved in the subsequent June pass.
