2012 Audi A6 2.0L Diesel · FG12 XKV

The 2012 Audi A6 presents a mixed maintenance picture. The most recent test on 19 November 2025 at 96,531 miles passed, but the record reveals a worsening trend in structural and suspension condition. Two consecutive MOTs, in November 2024 and November 2025, flagged worn suspension arm pins or bushes on both nearside and offside, alongside sub-frame corrosion. The sub-frame corrosion advisory has persisted since 2024, and the suspension wear has now appeared twice in succession, suggesting these components are deteriorating rather than being proactively replaced. A clean pass in November 2023 at 83,888 miles shows the car was once in better order, making the recent decline more pronounced. Mileage accumulation is consistent with typical use for a fourteen-year-old vehicle. The recorded distance grew from 75,602 miles in November 2022 to 96,531 miles by November 2025, averaging roughly 7,000 miles per year over that three-year window. There are no suspicious gaps or sudden jumps in the odometer readings, and the annual test dates fall within a normal November pattern. The 2023 failure and retest, occurring within days of each other at 83,781 and 83,888 miles, confirms the car was actively used and tested without long periods of inactivity. Buyers should focus their attention on the rear sub-frame and suspension components. The repeated advisory for sub-frame corrosion, noted as not seriously weakened in both 2024 and 2025, warrants a close physical inspection to verify structural integrity, particularly around mounting points and welds. The worn suspension arm pins or bushes on both sides indicate the front end may need fresh wishbones or bush kits soon. Brake wear has been a recurring theme. The 2023 failure flagged worn rear pads and scored rear discs, and the 2022 pass still noted worn and pitted rear discs, suggesting braking components have been a persistent weak point. A thorough check of rear disc thickness, pad material, and caliper operation is advisable. The 2022 advisory for a defective rear exhaust mounting and cracking offside rear tyre also points to deferred minor repairs that may still need attention.
