2002 Audi A6 4.2L Petrol · BD02 BHP

Corrosion on the coil springs and recurring issues with brake disc surface condition define the current mechanical profile of this Audi A6, following its most recent pass on 24 May 2025. The MOT history shows a trend of persistent advisories regarding brake disc wear, pitting, and scoring across multiple years, alongside a long-standing advisory for an oil leak that has been noted since at least 2023. While the vehicle has passed its tests, the presence of corrosion on both nearside and offside rear coil springs, combined with the repeated mentions of pitted brake discs, indicates that the braking and suspension components are subject to ongoing degradation. The vehicle has covered 111,043 miles over its 24-year lifespan, which equates to an average annual accumulation of approximately 4,627 miles. This represents a low usage pattern for a vehicle of this age. Mechanically, such low annual mileage can often lead to the specific issues observed in the records, such as the pitting and scoring on the brake discs and the binding of the offside front service brake recorded in 2020. Components that are not frequently used can be more susceptible to surface corrosion and seized moving parts, which is consistent with the documented history of brake and suspension advisories. Prospective buyers should pay close attention to the braking system and the suspension during a test drive. Given the repeated advisories for pitted and scored discs, as well as previous failures for binding brakes, it is essential to check for any pedal judder, uneven braking pull, or unusual grinding noises when slowing down. The advisory regarding the oil leak, which has persisted through several testing cycles, warrants a physical inspection of the engine bay and underbody to identify the source and determine if the leak is increasing. The recent advisories for corroded rear coil springs should also be a primary focus. On a test drive, listen for any knocking, clunking, or metallic banging sounds when driving over bumps or uneven road surfaces, which could indicate that the spring integrity is compromised or that the suspension bushes, previously flagged as worn, are contributing to instability. Additionally, since the vehicle has experienced issues with windscreen wiper effectiveness and tyre wear in the past, a visual inspection of all rubber components and tyre sidewalls is advisable to ensure they are free from cracking or damage.
