2003 Audi RS6 4.2L Petrol · LS53 OKP

The vehicle remains roadworthy but the maintenance history indicates a stable trend of developing mechanical degradation and component aging. The most recent test in July 2025 at 100,590 miles introduced new issues regarding perished rear tyres and a binding offside rear brake which were not present in the 2022 inspection. While the car consistently passes its tests, the persistent presence of an oil leak across the last three successful examinations suggests a long-term seal issue that the owner has prioritized over proactive preventative maintenance. At 23 years old, the recorded mileage of 100,590 miles is remarkably low, averaging approximately 4,373 miles per year. This low usage pattern explains the presence of age-related failures rather than mileage wear, such as the cracking of rubber hoses and tyres. Between February 2022 and April 2023, the vehicle covered only 3,290 miles, suggesting it sits for long periods. This inactivity often leads to the accelerated degradation of rubber-based components and the drying out of seals in a high-performance engine unit. A buyer must prioritize a thorough inspection of the braking system and fluid integrity. The tester flagged recurring corrosion on the nearside and offside front brake hoses in both 2024 and 2025, alongside a newly binding offside rear caliper in the latest test. These metal and rubber components require immediate replacement to prevent sudden catastrophic failure. The persistent oil leak needs professional tracing, likely originating from the valve cover gaskets or oil housing, as it has remained noted for years. Furthermore, the perishing of the rear tyres indicates that despite sufficient tread depth, the rubber compound has reached its structural life due to age.
