2012 Audi A6 2.0L Diesel · Y22 UBS

The 2012 Audi A6 most recently passed its MOT test on 19 March 2026, with a single advisory recorded for front tyres worn close to the legal limit and on the edge on both sides. Reviewing the recent history, the vehicle has achieved five consecutive passes without any failure items, which indicates that no serious safety or structural defects have been flagged over the last five test cycles. However, the pattern of advisories reveals a gradually worsening trend in several recurring areas, most notably suspension components, brake pipework, and tyre wear. While the absence of failures is reassuring, the accumulation of advisories year-on-year suggests that proactive maintenance will be required shortly after purchase to address corrosion-related deterioration and worn consumables. With 140,164 miles recorded over approximately 14 years of service, this A6 has covered an average of around 10,012 miles annually, which is broadly typical for a vehicle of its age and class. The mileage accumulation appears consistent and steady across the test record, with no extreme gaps or unusually rapid annual increases that would point to short motorway commutes or excessively long periods of standing unused. This relatively continuous usage pattern is mechanically favourable, as regular driving tends to keep seals, brakes, and the drivetrain in better working order than a vehicle left idle for extended periods. Nonetheless, the total odometer reading places the car into high-mileage territory, where wear-related items such as suspension bushes, engine mounts, and turbo components typically begin to demand attention. For a prospective buyer, the recurring advisory concerning the nearside front lower suspension arm pin or bush warrants particular attention, as it has appeared in both the 2024 and 2025 tests and is likely to have progressed further since. On a test drive, listen for clonking or knocking noises from the front suspension over speed humps, uneven road surfaces, and during full-lock low-speed manoeuvres, as these are classic indicators of worn bushes. Similarly, the brake pipe corrosion advisories from the 2023 and 2024 tests should prompt a careful inspection underneath the vehicle, looking for surface rust, pitting, or any active flaking on the underbody brake lines, particularly at unions and mounting clips. If corrosion is now penetrating the pipe wall, this will become an MOT failure at the next test, so budgeting for replacement of the affected sections would be prudent. The coil spring corrosion noted in 2022 and the front tyre edge wear from 2026 are also worth investigating closely, as corroded springs can weaken and ultimately fracture, while uneven tyre wear often points to misalignment or worn suspension geometry. Given the vehicle's age, it is also sensible to verify that the timing belt or chain service interval has been observed according to Audi's schedule, check the condition and age of the 12V battery, and confirm the brake fluid and coolant have been renewed within their calendar-based intervals regardless of mileage. Finally, given the high recorded mileage, a compression test or oil analysis can provide reassurance regarding internal engine condition, while inspecting the underside of the plastic undertray mentioned in the 2022 advisory will confirm it has not been dislodged, potentially exposing vulnerable components to road debris.
