2004 Audi A6 2.5L Diesel · BP04 TVF

Recurring issues with suspension components and drivetrain seals define the mechanical profile of this Audi A6, which shows a history of structural and linkage failures alongside persistent minor defects. While the most recent test on 25 May 2023 resulted in a pass with no defects recorded, the preceding years reveal a pattern of deterioration in the front-end geometry and CV boots. Most notably, a 2019 failure involved multiple dangerous defects regarding fractured nearside front suspension arms, indicating a period of significant mechanical instability that has since been addressed. The vehicle has covered 173,497 miles over its 22-year lifespan, averaging approximately 7,886 miles per year. This represents a typical usage pattern for a vehicle of this age, suggesting consistent rather than excessive road use. Mechanically, this level of annual accumulation means that while the vehicle has not been subjected to extreme high-mileage wear, the components are subject to the standard age-related degradation of rubber bushes, seals, and suspension linkages common to a car of this vintage. Prospective buyers should pay close attention to the suspension and drivetrain, as the MOT history shows repeated advisories for worn bushes and deteriorated CV boots. Specifically, the 2022 record flagged worn offside front shock absorber bushes and nearside rear lower suspension arm pins. During a test drive, listen for rhythmic knocking or clunking sounds when traversing uneven surfaces or speed bumps, which could indicate that these suspension bushes have degraded again. Additionally, pay attention to any steering pull or vibrations through the steering wheel, which may stem from the previously noted issues with the drive shaft constant velocity joints. The presence of oil leak advisories in 2017 and 2018 warrants a close visual inspection of the engine bay and underbody for fresh weeping or heavy accumulation of grime. While the 2023 test was clean, any signs of active oil misting or dripping should be investigated to determine if previous leaks were resolved or merely managed. Furthermore, given the history of tyre wear advisories and the 2019 suspension failures, the alignment and integrity of the steering and suspension components should be verified by checking for any uneven tyre wear or wandering at cruising speeds.
