2007 Audi A3 2.0L Diesel · MJ57 RCO

A pattern of recurring tyre wear and deteriorating CV boot condition dominates this 2007 Audi A3’s MOT history, with each annual test since 2022 flagging new major defects alongside persistent advisories. The most recent test on 24 October 2025 recorded a pass, but retained an advisory for an illuminated electronic mileage logger and noted corrosion on a rear suspension component that was judged not yet to compromise structural integrity. Earlier years show repeated warnings about front‑edge tyre tread approaching the legal limit, split constant‑velocity boots on both front drive shafts, and a major exhaust leak in 2022, indicating that wear‑related issues have been a continual concern rather than an isolated incident. At 195,578 mi the car averages roughly 10,300 mi per year, a mileage rate that sits squarely within normal usage for a vehicle of its age. There are no significant gaps in the MOT chronology, suggesting the odometer readings are consistent with the recorded testing intervals. Mechanically, this level of cumulative distance implies that consumable components such as tyres, brake pads, suspension bushings and drivetrain joints have been subjected to moderate to high wear cycles, and the recurring nature of the advisories suggests that some of these wear items may be approaching the end of their service life. Prospective buyers should give particular attention to the front CV boots that have been recorded as split or insecure on both sides. On a test drive, listen for a rhythmic clicking or whining noise that changes with steering angle and acceleration, and inspect the boots for grease leakage or exposed joints. The rear suspension corrosion noted in the latest advisory warrants a visual inspection of the rear subframe, trailing arm bolts and bushings for rust flaking or pitting; any clunking over bumps could indicate that the corrosion is progressing toward structural weakening. Tyre condition should be verified against the recorded edge‑wear warnings – examine the front and off‑side tyres for uneven tread, especially on the edges, and be prepared to replace them if the remaining depth is below 1.6 mm. The off‑side rear brake pads were previously flagged as thin, so a pedal feel test for reduced braking efficiency or a squealing noise under moderate braking is advisable. The exhaust system should be inspected for the previously reported major leak, which may manifest as a hissing sound at idle or a noticeable increase in cabin noise, and any black smoke on acceleration. The parking brake was recorded as failing to meet efficiency requirements in 2023; a simple hand‑brake hold test on a slight incline will reveal whether the mechanism still provides adequate holding force. Finally, confirm that the near‑side stop lamp operates correctly and that the electronic mileage logger illumination is resolved, as these items were cited in multiple tests. Addressing the CV boots, tyres, brake pads, rear suspension corrosion and exhaust leak before purchase will significantly improve the car’s roadworthiness and reduce the likelihood of imminent failures.
