2009 Audi A6 3.0L Diesel · OV09 ECW

The latest recorded MOT from August 2022 resulted in a pass, although the overall maintenance trend appears reactive rather than proactive. There is a noticeable pattern of recurring advisories being carried over across multiple years, specifically regarding the rear shock absorbers and exhaust leaks, which suggests that minor defects are often left unaddressed until they potentially become critical. The most recent entries shift the focus toward the braking system, indicating that while the vehicle remains roadworthy, it is entering a phase where several major consumables require simultaneous replacement. With a recorded mileage of 233,143 miles over seventeen years, this vehicle has averaged approximately 13,714 miles per year. While the annual usage is moderate, the total cumulative mileage is exceptionally high for a luxury saloon of this vintage. Such high mileage places significant mechanical stress on the drivetrain, engine internals, and chassis components. A buyer should anticipate accelerated wear on the turbocharger, transmission internals, and various rubber suspension bushings, all of which are prone to degradation and fatigue at this stage of the vehicle's lifecycle. The MOT history highlights a chronic issue with the nearside rear shock absorber, which showed oil misting and limited damping from 2019 through 2021. During a test drive, listen for knocking or clunking sounds over uneven surfaces and observe if the rear of the car bounces excessively after a bump. The recurring exhaust leak advisory suggests a potential failure in the manifold or weld joints; listen for a rasping sound or an increased drone under acceleration. Furthermore, the 2022 advisories regarding lipped brake discs and thin pads indicate that the braking system is nearing the end of its service life. Feel for any shuddering through the brake pedal during deceleration, which would confirm the presence of disc warping or excessive lipping. Given the high mileage and the evidence of inner tyre wear in previous tests, a thorough inspection of the front suspension geometry and steering rack is essential. Check for uneven tread wear on the current tyres, as this often points to worn control arm bushes or incorrect wheel alignment. Additionally, verify the service history to ensure that the timing belt and water pump have been replaced according to the manufacturer's intervals, as a failure at this mileage would be catastrophic. Finally, inspect the underbody for structural corrosion, particularly around the suspension mounting points, to ensure the chassis remains sound despite the high usage.
