2015 Audi A6 2.0L Diesel · DF15 ABK

A pattern of rear‑tyre wear and a deteriorating nearside front drive‑shaft CV boot defines this 2015 Audi A6’s MOT record; the tyre edge‑wear advisories appear in every test from 2023 to 2024 and the CV boot progressed from a minor advisory in 2025 to a major failure in early 2023 before being cleared in the most recent March 2026 pass. Apart from an isolated exhaust‑mount clamp advisory in 2024 and a windscreen‑wiper defect that caused a failure the same year, the car has otherwise passed its annual tests without recorded defects, indicating that the highlighted areas are the primary mechanical concerns to verify. At 142,092 mi the vehicle averages roughly 13,000 mi per year, a mileage level that exceeds the typical usage for a car of this age and suggests accelerated consumption of wear items such as tyres, suspension bushings, brake pads and drivetrain components. The MOT history shows no gaps, confirming continuous road use and that the mileage has been accumulated under regular operating conditions rather than long periods of storage, which places greater emphasis on the condition of wear‑related parts. When inspecting the car, give the rear tyres a thorough visual and tactile check for uneven tread depth, side‑wall cuts or embedded nails that may have prompted the repeated advisories; confirm that the tyre pressures are correct and that there is no vibration or pulling at speed, which could indicate underlying alignment or suspension issues. Examine the nearside front CV joint boot for cracks, splits or missing clips, and listen for a clicking or clunking noise when accelerating from a standstill or when turning, as these symptoms would reveal residual joint wear despite the MOT pass. The central exhaust mounting clamp should be probed for looseness or rattling under engine load, as a defective clamp can lead to exhaust vibration and eventual corrosion of surrounding components. Given the high mileage, a practical test‑drive should also include a brief evaluation of the braking feel – ensuring pedal travel is consistent and there is no judder or pulsation that might hint at pad or disc wear not captured by the MOT – and a short inspection of the front suspension for any knocking over bumps, which could signal worn bushings or coil‑spring fatigue. Addressing the rear‑tyre condition, confirming the integrity of the CV boot and exhaust mount, and listening for any abnormal noises will provide a realistic picture of the car’s current roadworthiness beyond the recorded MOT outcomes.
