2009 Audi A6 E SE TDI 2.0L Heavy oil · IFZ 4658

An unbroken chain of eight consecutive faultless annual examinations defines the roadworthiness profile of this Audi A6, which secured its most recent pass on 29 October 2025 with zero defects recorded. This clean run extends back through 2017 without a single failure or advisory logged on the official DVSA testing record. Such a uniform string of passes indicates that the vehicle has consistently met statutory roadworthiness standards during its annual checks, though a pass certificate confirms only that minimum standards were met on the day of the test rather than guaranteeing overall mechanical health. Accumulating a total of 95,052 miles across roughly seventeen years yields an average of approximately 5,591 miles per year, representing a notably low usage profile for an executive diesel saloon. This light annual mileage means the car has spent extended periods operating on short urban journeys or sitting idle between tests. A notable testing gap appears between September 2019 and August 2021, during which time no MOT test was recorded, suggesting the vehicle may have been laid up off the road for a significant duration. Low and interrupted usage patterns of this nature place distinct stresses on heavy diesel powertrains and auxiliary systems. Without regular long-distance running, components such as the diesel particulate filter, exhaust gas recirculation valves, and variable-geometry turbocharger mechanisms are susceptible to carbon fouling and sticking actuators. On a test drive, listen carefully for sluggish turbo spooling, hesitation under acceleration, or erratic idling, and check the dashboard for any stored diagnostic fault codes related to emission control systems. Although the testing history is entirely free of structural or mechanical advisories, the physical inspection and test drive must focus heavily on the complex multi-link front suspension and braking assemblies common to this platform. Pay close attention to the ride quality over rough road surfaces, listening for dull knocks, clonks, or excessive play from the suspension arms and drop links, which often wear prematurely under the heavy front-end weight of the TDI engine. Furthermore, test the braking system thoroughly for even deceleration, ensuring the vehicle tracks straight when the pedal is applied and checking that the electronic parking brake engages and disengages smoothly without binding calipers.
