2015 Audi A6 2.0L Diesel · K99 GCH

The 2015 Audi A6 has maintained a clean MOT history over the past five annual tests, with no defects recorded in any of the January 2022 to January 2026 tests. The most recent inspection on 27 January 2026, at 203,245 miles, confirms the vehicle remains roadworthy under current DVSA standards, though the gap until today—six months—means some components may now be approaching their typical service intervals. The absence of advisories or recurring faults suggests previous owners adhered to basic maintenance, though this does not guarantee hidden issues such as internal suspension wear or drivetrain degradation. The vehicle’s mileage progression indicates consistent high usage, averaging approximately 18,477 miles annually over the past five years. This is above the typical annual mileage for a car of this age, which could imply heavier-than-average use or prolonged periods of active service. Notably, the mileage increments between tests remain steady, with no abrupt jumps or extended gaps suggesting neglect—between January 2025 (193,463 miles) and January 2026 (203,245 miles), the vehicle accumulated roughly 9,782 miles in a year. While this pattern does not signal immediate cause for concern, it does warrant scrutiny of high-wear items such as suspension bushes, coil springs, and brake calipers, which may now require replacement or inspection. Given the lack of MOT advisories, a buyer should prioritise an independent inspection of the suspension geometry, particularly the rear bushings and track arms, which often degrade at this mileage. The brakes, while not flagged, should be checked for uneven wear or binding calipers, especially if the vehicle has been driven hard. Corrosion around wheel arches, sills, and the subframe—common in older Audis—must be examined closely, as structural integrity is critical for safety. The exhaust system should also be inspected for leaks or excessive rust, as emissions-related failures are not recorded in the MOT history but can develop silently. Finally, the engine bay fluids (oil, coolant, brake fluid) should be checked for contamination or low levels, as these are not routinely tested during MOTs.
