2005 Audi A6 1.9L Diesel · WM54 EHT

Recurring failures and advisories related to braking components and tyre wear define the roadworthiness history of this vehicle. While it achieved a pass on 27 June 2023, this followed a failure for a perished constant velocity boot and left a lingering advisory regarding a minor exhaust gas leak from the flex pipe. The overall trend shows a pattern of consumables reaching critical wear limits before being addressed, particularly evident in the 2019 test where multiple tyres and brake pads were recorded as dangerous. With 188,272 recorded miles over 21 years, the vehicle has averaged approximately 8,965 miles per year, which is typical for its age. This level of accumulation suggests a consistent usage pattern, but the high absolute mileage increases the likelihood of wear on major drivetrain components, suspension bushings, and engine mounts. There is a notable gap in testing between December 2021 and June 2023, which may indicate a period of reduced use. Attention should be paid to the exhaust system, specifically the flex pipe, as the minor leak noted in June 2023 may have progressed. During a test drive, listen for an increased roar or rasping sound from under the cabin, which would indicate the leak has worsened. Given the previous failure for a nearside front outer prop shaft joint boot, it is essential to verify that this was replaced and that the joint is not now clicking or popping during tight, low-speed manoeuvres. The braking system has been a recurring point of concern, with multiple records of worn, pitted, and scored rear discs and thin pads between 2018 and 2020. A test drive should include firm braking from various speeds to check for pedal judder or uneven deceleration, which would suggest the rear discs remain pitted or warped. Additionally, ensure the current tyre tread is consistent across all four corners, as the 2019 record showed a dangerous lack of tread across the entire set.
