2009 Audi A6 2.0L Diesel · SA59 XTB

The 2009 Audi A6 presents a stable and improving maintenance trend, culminating in a clean pass on 13 November 2025 at 175,208 miles. The only advisory recorded at that most recent test was a non-reductive product on the offside headlamp lens, a minor cosmetic issue that does not affect beam pattern or safety. Crucially, the vehicle has not presented any braking, suspension, or structural defects in its last three consecutive annual tests, indicating that major mechanical systems are currently in sound working order. The mileage accumulation of roughly 10,306 miles per year is entirely typical for a vehicle of this age and suggests consistent, regular use rather than prolonged standing or extreme high-mileage abuse. The annual test intervals from November 2022 through November 2025 show steady, predictable jumps of approximately 7,300 to 7,700 miles per year, with no suspicious gaps or sudden spikes that would raise concerns about odometer tampering or extended periods of neglect. The record is clean and well-documented across this period. A buyer should still conduct a thorough physical inspection focused on the components that historically drew attention. In November 2022, all four tyres were flagged as worn close to the legal limit and worn on the edge, suggesting possible wheel alignment issues or suspension geometry wear that may have recurred between tests. Inspect the inner and outer edges of all four tyres for uneven wear patterns, and check the condition of the front and rear suspension bushes, track rod ends, and drop links. The failed engine MIL test on 22 November 2023, passed on the same day, indicates a stored or intermittent fault code that may have been cleared rather than properly diagnosed. A pre-purchase OBD scan is advisable to check for pending or historical fault codes related to the engine management system, exhaust emissions, or catalytic converter efficiency. Given the vehicle's age and mileage, a careful underbody inspection for corrosion is essential, particularly around the subframes, sills, and suspension mounting points. The headlamp lens advisory, while minor, warrants a check for moisture ingress or internal condensation that could indicate a compromised seal. Overall, the MOT record reflects a vehicle that has been maintained to a reasonable standard in recent years, but the tyre wear pattern and the engine MIL history justify a focused mechanical inspection before purchase.
