2009 Audi A6 3.0L Diesel · LT09 GVJ

Recurring structural corrosion and persistent suspension component wear define the mechanical profile of this Audi A6, with the most recent MOT pass on 31 March 2025 confirming ongoing issues. The vehicle shows a consistent pattern of advisories regarding rear subframe corrosion and worn rear suspension arm bushes, both of which have been noted in multiple consecutive tests since at least 2023. While the 2025 result indicates the subframe is not yet seriously weakened, the repetition of these defects suggests a progressive degradation of the chassis and suspension mounting points that requires close monitoring. The vehicle has covered 208,648 miles over its 17-year lifespan, representing an average annual accumulation of approximately 12,273 miles. This usage level is relatively high for a vehicle of this age and aligns with the mechanical wear observed in the MOT history, particularly regarding the degradation of rubber bushes and the presence of an ongoing oil leak. High-mileage vehicles of this type typically experience increased stress on drivetrain components and suspension linkages, which is reflected in the recorded failures for anti-roll bar linkages and upper suspension arm bushes. Prospective buyers should pay particular attention to the chassis and underbody during a physical inspection, specifically looking for the extent of the reported rear subframe corrosion. On a test drive, listen for knocks, clunks, or imprecise steering responses when traversing uneven surfaces or bumps, as these are common symptoms of the worn rear suspension arm bushes and anti-roll bar linkages flagged in previous tests. Any noticeable pulling to one side or vibration through the steering wheel may indicate that the suspension wear has progressed beyond the advisory stage. The presence of a non-excessive oil leak, noted in every test from 2023 through 2025, necessitates a careful inspection of the engine bay and underside to identify the source. While currently listed as not excessive, the leak should be monitored to ensure it does not affect belt operation or increase in volume. Additionally, given the history of lighting failures and the recent advisory regarding undertrays obscuring components, a thorough check of all exterior lamps and the condition of the lower vehicle shielding is advised to ensure full visibility and component accessibility.
