2001 Audi A6 1.9L Diesel · Y684 AAB

The mechanical narrative across the seven recorded MOT tests is dominated by a chronic and worsening pattern of suspension and brake deterioration rather than a clean record of roadworthiness. Two failures appear in the history, the most recent being a PRS on the 2020 test for an obstruction in the driver's swept windscreen area from items hanging from the mirror, alongside a deteriorated offside front CV boot that was also listed as a minor. The earlier 2019 failure was more serious mechanically, flagging severely reduced headlamp intensity on both sides, an excessively worn offside front upper suspension arm pin or bush with excessive play, and a nearside track rod end with excessive play. Even the passed tests carry a striking concentration of advisories: the 2022 pass noted corroded coil springs at all four corners plus an oil leak; the 2021 pass noted all four coil springs corroded, worn front and rear arm bushes, and corroded rear brake pipes; and the 2018 pass and its associated failure both recorded worn upper suspension arm pins or bushes, corroded front coil springs, and a braking system only just meeting requirements. Read together, the record points to a chassis and underbody that has been progressively shedding its margin of safety, with the suspension, braking, and steering components all showing repeated age-related wear. Mileage stands at 235,142 across an annual rate of roughly 9,406 miles, which is broadly typical for a 25 year old vehicle, but the test gap between the 2019 and 2020 entries and the consistent year on year testing from 2018 through 2022 suggests the car has been in regular use rather than laid up, meaning the wear flagged is genuine accumulated service wear rather than deterioration from standing. The relatively high absolute mileage means consumables such as brake discs, pads, CV joints, bushes, springs, and engine sealing components have all been heavily worked. The chronic advisories on coil springs, suspension bushes, and brake pipes are entirely consistent with a high mileage car of this age being driven over salted winter roads, and the fact that advisories have escalated from front arm bushes in 2018 to all four coil springs and rear brake pipes by 2021 suggests corrosion and bushing deterioration has been progressive rather than arrested. For a prospective buyer, the underbody and suspension should be the priority areas for physical inspection and test drive scrutiny. Pay particular attention to clonks, knocks, or a loose feeling over uneven surfaces, especially from the front upper suspension arms and rear arm bushes that were repeatedly flagged, as worn pin or bush wear progresses towards the kind of excessive play that caused the 2019 failure. With corroded coil springs recorded at all four corners across consecutive tests, listen for sagging or uneven ride height and check for spring snap risk by inspecting closely for any visible cracks at the spring coils. The 2019 nearside track rod end failure is a critical steering component, so any vague wandering, uneven tyre wear, or knocking from the front end on full lock should be treated as a red flag. The 2018 advisory on braking performance only just being met indicates the system has been on the edge of acceptability for some time, so a firm pedal test from speed is worthwhile, checking for pull to one side, judder, or a soft pedal, and the 2021 advisories on rear brake pipe corrosion mean the underside brake lines should be physically inspected for rust pitting or flaking, particularly behind the rear wheels. Additional items worth checking on a physical inspection include the 2022 oil leak advisory, which warrants a close look at the engine and gearbox sump area for fresh seepage and a check of oil level and condition on the dipstick, as an unresolved leak at this mileage can quickly escalate into a more serious gasket or seal failure. The offside front CV boot flagged as severely deteriorated in 2020 should be re-examined for splits or grease loss, as a torn boot left unreplaced leads rapidly to joint failure. The 2019 headlamp intensity issue may have been resolved but warrants confirmation that both lamps are producing clean, even illumination with no signs of clouded lenses or failing reflectors, particularly given the car's age. Finally, with front wing corrosion already advised in 2021, inspect both front wings closely for rust bubbling around the arches, jacking points, and lower seams, as this is a known corrosion hotspot on this model and can affect structural integrity if left to develop.
