2012 Audi A8 3.0L Diesel · A8 XFL

A clear pattern in the MOT history is the gradual deterioration of the braking system and tyre tread, with multiple advisories on front and rear discs and the nearside rear tyre appearing in the last two years, and a single failure recorded for insufficient washer‑fluid supply. The 2024‑12‑10 test ultimately passed after the washer‑fluid issue was rectified, confirming that the vehicle meets the legal minimum for that item, but the persistence of brake‑disc advisories suggests the discs are approaching the end of their serviceable life. At 153,983 mi the car averages just under 11,000 mi per annum, a mileage rate that sits squarely within normal usage for a fourteen‑year‑old executive saloon. The MOT schedule shows regular annual testing with only a short six‑month gap between the 2019 June test and the 2020 December test, indicating no prolonged periods of inactivity that might conceal hidden deterioration. This steady accumulation of miles aligns with the observed wear on the braking components and tyre, as higher kilometre counts naturally accelerate disc surface fatigue and tread loss. Prospective buyers should focus the test drive on the braking system: feel for any pulsation or sponginess in the pedal, listen for squeal or grinding that could indicate thinning pads or warped discs, and inspect the discs for scoring beyond the advisory description. The nearside rear tyre is already within three millimetres of the legal limit and shows edge wear, so a visual check for uneven wear patterns, sidewall cracks or bulges is essential, and budgeting for replacement on the front and rear axles is prudent. The washer‑fluid fault points to a possible leak or pump issue; a quick functional test of the windscreen cleaning system will confirm whether the problem has been fully resolved. The windscreen crack noted in 2018, although not yet impairing the driver’s view, sits close to the swept area and should be re‑examined for propagation, especially under thermal stress or vibration. While no other components have attracted advisories, a comprehensive visual inspection of suspension bushes, steering linkages and exhaust mounts is advisable, as these items are not captured by MOT unless they present a safety‑critical defect. Confirm that the brake pads have sufficient thickness, that the caliper pins move freely, and that there is no visible corrosion around the wheel hubs before committing to purchase.
