2020 Audi A4 S Line 30 TDI S-A 2.0L Diesel · JC61 LRC

The vehicle most recently failed its MOT test on 26 August 2026 due to a dangerous defect regarding the nearside front tyre tread depth. While the history from 2023 to 2025 remained relatively stable with only a minor failure for a windscreen washer, the most recent result indicates a concerning decline in basic safety maintenance. The presence of a dangerous failure, coupled with advisories for the remaining rear tyres, suggests that the vehicle has been neglected in its final months of ownership, shifting the maintenance trend from stable to worsening. With a recorded mileage of 96,358 miles over approximately six years, this vehicle has averaged roughly 16,060 miles per year. This is significantly higher than the UK average and suggests heavy usage, likely consisting of long-distance motorway commuting. While motorway miles are generally less taxing on the engine than urban stop-start traffic, the high overall accumulation accelerates the wear of critical consumables, including suspension bushes, brake components, and drivetrain mounts. Immediate attention must be paid to the tyres, as the MOT record indicates that the entire set is either below the legal limit or worn on the edges. A prospective buyer should inspect the tread across the full width of each tyre to determine if uneven wear is present, which would point toward wheel misalignment or worn suspension components. During a test drive, listen for any knocks or clunks from the front end and feel for vibrations through the steering wheel, which may indicate that the high mileage has compromised the control arm bushes or wheel bearings. Given the mileage is approaching the 100,000-mile threshold, it is imperative to verify the service history regarding the timing belt and water pump replacement, as these are critical time and mileage-based items for the 30 TDI engine. Additionally, check for any signs of oil seepage around the engine bay and ensure the diesel particulate filter is functioning correctly by monitoring for unusual exhaust smoke or loss of power. Inspect the brake discs for significant lipping or corrosion and confirm that the automatic gearbox shifts smoothly without hesitation, as high-mileage transmissions require strict adherence to fluid change intervals.
