2004 Audi A6 3.0L Diesel · YR54 AHA

The most recent MOT on 2024‑01‑09 ended in a failure, even though the record shows no defects. This outcome follows a pass at the end of 2021 and creates an unstable maintenance pattern; the vehicle moved from a clean pass to a documented fail within 15 months without any recorded faults, hinting at possible undocumented issues or inconsistent test conditions. The lack of detailed defect entries makes the cause of the failure unclear. Mileage has risen steadily from 123,175 miles in November 2021 to 146,058 miles in January 2024, averaging roughly 6,600 miles per year. The gap between that latest test and the current date of August 2026 is about 2.5 years, which exceeds the standard annual MOT interval and leaves a considerable period without an official roadworthiness assessment. The data shows a consistent accumulation rate with no sudden jumps, indicating regular use rather than extended storage periods. With no specific recurring faults logged, a buyer should concentrate on the high‑wear systems typical of a 22‑year‑old, 146k‑mile Audi A6. Examine the brake discs, calipers and pads for binding or uneven wear, check suspension bushes and coil springs for cracking, oil leakage or wear, and inspect the exhaust and under‑body for corrosion or rust, especially around wheel arches and sills. Verify the structural integrity of the chassis and assess any after‑market modifications or service history gaps; a visual inspection of the oil condition and fluid levels will also provide insight into prior maintenance quality.
