1998 Audi A6 2.4L Petrol · S558 RUJ

The vehicle currently presents a concerning roadworthiness profile with a clear trend of worsening mechanical degradation and structural corrosion. While it passed its most recent test in October 2025 at 143,492 miles, this followed a significant failure just one week prior. That failure revealed a multitude of critical issues including a binding nearside front brake, steering rack inner joint play, and exhaust fumes entering the cabin. The persistent presence of corroded coil springs and a rear axle beam across multiple years indicates that age-related components are failing without proactive replacement. At 28 years old, the recorded mileage of 143,492 miles represents a low average of approximately 5,125 miles per year. However, the data shows a distinct lack of use recently; between October 2024 and October 2025, the vehicle covered only 269 miles. This period of low activity often correlates with the observed deterioration of rubber-based components and the seizure of braking system parts, as evidenced by the deteriorated brake hoses and pitted brake discs noted in the 2022 and 2023 records. A buyer must conduct a thorough physical inspection of the structural integrity, specifically the sills and rear axle beam, which testers have repeatedly been unable to fully inspect due to fitted covers. The recurring reports of corrosion on the sub-frame and exhaust system suggest a high risk of structural thinning. Immediate attention is also required for the steering rack and front suspension arm bushes, which have been flagged for wear in consecutive tests. The history of engine and gearbox oil leaks noted since 2022 further suggests that seals are reaching the end of their service life, which may necessitate costly repairs.
