2015 Audi A6 2.0L Diesel · CV15 VDD

The most recent DVSA examination on 15 April 2026 resulted in a Pass, although the test attracted four advisories that warrant close attention from any prospective buyer. Reading the recent history in sequence, the trend is one of emerging rather than acute concern: the April 2023 and earlier tests were entirely clean, but the 2024 and 2026 tests have begun to surface brake, suspension and tyre advisories, and an intermediate failure occurred on 2 April 2025 for fractured rear coil springs and worn front suspension arm pins or bushes on both sides. All of those major items were clearly rectified, as the vehicle subsequently passed on 16 April 2025 with only a corroded rear sub-frame noted. The overall picture therefore suggests a car that is being maintained but is entering a phase where consumable and chassis components are requiring more frequent replacement, consistent with its age and mileage bracket. With 111,117 miles recorded against an 11 year old vehicle, this Audi A6 has averaged approximately 10,100 miles per year, which is broadly typical for its age and indicates regular rather than incidental use. The MOT record shows annual tests without large unexplained gaps, which is reassuring for continuity of use, and there is no evidence of a long stationary lay-up that might otherwise accelerate issues such as brake disc corrosion, perished coolant hoses or a discharged 12 volt battery. The mileage accumulation is steady rather than rapid, meaning wear should be evenly distributed across major mechanical assemblies rather than concentrated from heavy sustained high mileage, though consumable items such as brake discs, pads, tyres, suspension bushes and timing chain stretch on the higher-output petrol or diesel variants should still be regarded as having covered significant working life. The April 2025 failure and the advisories issued since merit particular scrutiny on a physical inspection. The nearside and offside front suspension arm pins or bushes that were flagged as excessively worn are a known wear item on C7 platform Audis and, if not fully replaced with quality components, can recur quickly and present as a clonking or knocking noise from the front end over speed humps, uneven tyre wear across the front axle, and vague or wandering steering. The fractured rear coil springs recorded on both sides in 2025 are a safety-critical failure that can allow the affected corner to sit noticeably low and may produce a harsh, thumping ride over bumps; any prospective buyer should check visually that the rear ride height is level and that there is no evidence of new fractures, paying attention to any noise when travelling over undulating roads. Given that the April 2026 test also recorded a nearside front tyre worn close to the legal limit on the inner edge, suspension geometry should be considered, as inner-edge wear typically points to misalignment or worn suspension linkages rather than simple tyre ageing, and a four-wheel alignment check would be prudent alongside any front suspension work. The most recent advisories concerning the rear brake discs being worn, pitted or scored, and both rear service brakes binding slightly, suggest that the rear braking system is also approaching a service interval. Brake binding of this nature often stems from corroded or seized slider pins on the rear calipers, a frequent issue on vehicles that see mixed urban and motorway use, and can manifest as a pulling sensation under light braking, uneven brake pad wear, or a hot smell from one wheel after use. A test drive should include several progressive brake applications to check for any pulling, shudder through the steering wheel, or roughness underfoot. In addition, the noted corrosion on the rear sub-frame, while currently not seriously weakened, will progress over time and should be inspected periodically, particularly around mounting points and weld seams. Finally, despite the absence of specific MOT advisories on fluids or battery condition, an eleven year old vehicle with this mileage should be approached with attention to age-related deterioration not visible on an MOT, including the state and age of the timing belt or chain service interval on the installed engine, the colour and specific gravity of the coolant, the condition of brake fluid which degrades hygroscopically over time, the 12 volt battery health, and a careful look for fluid leaks around the turbo, oil filter housing and front cam chain cover which are known weak points on this generation of A6.
