2021 Audi TT 2.0L Petrol · BK71 YHS

Recurring rear‑brake disc wear dominates the MOT record, appearing as an advisory in both the 2024‑08‑12 and the most recent 2026‑01‑22 tests, while a near‑side rear tyre condition was flagged in the latest inspection. Both examinations resulted in a pass, indicating that the identified issues have not yet breached the safety thresholds, but the persistence of the brake‑disc advisory suggests a component that is approaching the end of its service life and may require attention in the near future. At 24,636 mi after five years, the car averages just under 5,000 mi per annum, which is low for a 2021 Audi TT. Such mileage typically translates to reduced cumulative wear on major wear items such as tyres, brakes and suspension, yet the repeated brake‑disc advisory indicates that wear has occurred disproportionately to the mileage, possibly due to spirited driving or the original disc thickness being modest. The low annual accumulation also means that other age‑related factors, such as rubber hardening or corrosion, could be present despite the modest use. Prospective buyers should inspect the rear brake discs for remaining thickness, surface scoring and any signs of uneven wear; a professional measurement against the manufacturer’s minimum specification is advisable. During a test drive, listen for any squeal or grinding when applying the rear brakes and feel for pedal pulsation or a soft, spongy feel, which could indicate disc degradation or uneven pad wear. The near‑side rear tyre should be examined for sidewall cracks, bulges or tread depth below the legal 1.6 mm limit, and any damage should be rectified promptly to maintain safe handling. Although the MOT history shows no other recorded defects, a comprehensive pre‑purchase inspection remains prudent. Verify the condition of the suspension bushes, coil springs and steering linkages for play or corrosion, and confirm that the exhaust system is free of leaks. Checking the brake fluid level and condition, as well as the operation of the ABS sensors, will round out the assessment and help ensure that the vehicle’s low mileage has not concealed latent wear elsewhere.
