2010 Audi A6 2.0L Diesel · CM55 MCB

The 2010 Audi A6 shows a stable roadworthiness trend over the past five MOT cycles, with the most recent test on 15 April 2025 at 183,319 miles passing without any defects. This consistency suggests the vehicle has been maintained at a baseline standard, though the absence of advisories or faults does not preclude underlying wear in high-stress components. The near-annual testing interval—with no gaps exceeding 15 months—indicates compliance with legal requirements, but buyers should treat this as a baseline rather than a guarantee of current condition. The only anomaly is the duplicate entry for April 2022, where the vehicle failed at 162,168 miles before passing the following day at 162,169 miles, a detail that may warrant closer scrutiny of the test centre’s handling of the inspection. The recorded mileage of 183,319 miles over 16 years reflects an average of approximately 11,457 miles annually, a rate typical for a vehicle of this age. There are no significant gaps in mileage accumulation, though the jump from 162,169 to 164,579 miles between April 2022 and April 2023 suggests either a period of reduced use or a temporary storage phase. The lack of advisories or defects across all tests implies no obvious neglect in consumables like brakes or tyres, though the absence of detailed MOT reports means critical components such as suspension bushes, coil springs, or binding calipers cannot be confirmed as intact. The most recent MOT was conducted just over three years ago, meaning some components may now exceed their expected service life without intervening maintenance. Given the vehicle’s age and mileage, a buyer should prioritise an independent inspection of the suspension system, particularly the rear bushes and coil springs, which are prone to fatigue and cracking over 16 years. The brakes, while not explicitly failed, should be assessed for uneven wear, glazing, or corrosion on the discs and pads, especially if the vehicle has experienced prolonged periods of low use. Structural integrity—including the subframe, sills, and wheel arches—must be examined for corrosion, as Audi A6 models from this era are susceptible to rust progression in high-stress areas. Additionally, the exhaust system should be checked for leaks or excessive corrosion, particularly around the catalytic converter and oxygen sensors, which often fail or degrade after extended use. The absence of advisories in past tests does not rule out these issues, but it does suggest they have not yet reached a fail-safe threshold.
