2010 Audi S4 Avant 3.0L Petrol · X21 RTW

The vehicle is currently roadworthy, but the maintenance trend indicates a pattern of deferred repairs on mechanical components. While the most recent test on 1 June 2026 at 100,508 miles passed, it revealed a new holed nearside front steering arm boot and a defective wiper blade. This follows a period where the car failed tests due to significant suspension wear and brake issues, suggesting that the owner only addresses faults when they necessitate an MOT failure rather than performing preventative maintenance. At 100,508 miles over 16 years, the Audi has averaged approximately 6,282 miles per year, which is consistent with typical low-mileage usage. The mileage data shows consistent use, with roughly 1,800 miles covered between May 2024 and June 2025, and another 960 miles between June 2025 and June 2026. This steady usage suggests the car has not sat stationary for long periods, though the age of the vehicle means rubber components are likely nearing their natural degradation. A buyer must scrutinise the front suspension assembly, as the record shows a persistent history of worn upper and lower arm pins and bushes. These issues progressed from excessively worn in May 2024 to not resulting in excessive movement by June 2025, only for a steering arm boot to fail in the 2026 test. The tester also noted a non-excessive oil leak and a minor exhaust leak on the center pipe in 2025, which require monitoring to ensure they do not escalate. The braking system also requires attention, as rear pads were recorded as being below 1.5mm thickness in June 2025 after being flagged thin the previous year. While the surface rust on the underside was noted as minor in 2025, a physical inspection of the structural integrity is necessary to ensure that corrosion has not progressed beyond surface-level. The differential fault on the dashboard reported in 2025 should also be verified to ensure it is a simple sensor error rather than a deeper mechanical failure.
