2005 Audi A6 2.0L Diesel · BN05 CDV

Structural integrity and recurring suspension wear define the mechanical profile of this Audi A6, with a history of advisories concerning sill deformation and corrosion dating back to 2021. The most recent MOT test on 08 May 2026 shows a pass, but follows a failure for an offside rear tyre with tread depth below the legal limit. While the latest record notes that previous repairs to the front vehicle structure have not significantly reduced structural rigidity, the persistent mention of sill issues and subframe corrosion across multiple years indicates a long-term pattern of metal degradation that requires close monitoring. The vehicle has covered 102,138 miles over its 21-year lifespan, representing an average annual accumulation of approximately 4,864 miles. This is a low rate of mileage for a vehicle of this age, which can often lead to specific mechanical considerations. While lower mileage generally suggests less wear on high-frequency components, it can also coincide with periods where rubber components, such as the suspension bushes and track rod end dust covers flagged in previous tests, may perish or become brittle due to age rather than physical friction. Prospective buyers should pay close attention to the chassis and suspension during a physical inspection and test drive. The MOT history identifies a history of worn suspension arm bushes, worn ball joints, and slight free play in the steering rack. On the road, these issues may manifest as knocking or clunking noises when driving over uneven surfaces, or a vague, imprecise feeling through the steering wheel. Furthermore, the recent advisory for a non-excessive oil leak and previous notes regarding misting shock absorbers suggest that seals are beginning to fail. You should check for any visible fluid pooling under the engine bay or dampness on the shock absorber bodies. Braking components and lighting also require scrutiny based on the recorded advisories. The 2026 test flagged nearside rear outer brake pads as wearing thin, so you should listen for any squealing during braking or feel for any unevenness in pedal pressure. Additionally, the history of deteriorating registration plates and headlamp lens clouding suggests that various external consumables are reaching the end of their functional life. Ensure that the recent structural repairs to the sills are documented and that there is no evidence of fresh, advancing corrosion around the previously noted deformed areas of the integral body structure.
