2017 Audi TT 1.8L Petrol · AP17 AAK

The most recent MOT on 17 November 2025 recorded a pass, but it was accompanied by a suite of tyre advisories covering all four wheels – front‑near side tyre showing cracking and approaching the legal tread limit, rear‑near side tyre similarly worn and cracked, rear‑off side tyre also showing perishing, and a nail still noted in the near‑side rear. Earlier tests in 2023 flagged the same pattern of cracking and a nail, while the 2024 and earlier years showed no recorded defects. The trend is therefore one of worsening tyre condition despite an otherwise clean mechanical record, indicating that tyre degradation is the dominant issue at present. At nine years old the Audi TT has only 50,303 miles on the clock, equating to roughly 5,600 miles per annum – well below the typical UK average. Such low utilisation often points to periods of infrequent use or prolonged storage, which can exacerbate age‑related decay even when mileage is modest. The relatively static mileage means that wear on engine, transmission and suspension components is likely to be light, but the calendar age raises concerns about rubber perishing, battery sulphation and the potential for corrosion on brake discs and suspension joints that have not been exercised regularly. Prospective buyers should give the tyre set immediate attention. All four tyres exhibit signs of cracking or perishing, and two are close to the legal tread depth; a nail remains lodged in the near‑side rear, which could cause a slow leak or sudden failure. Replace the entire tyre complement with a matched set appropriate for the TT’s high‑performance chassis, and have the wheel rims inspected for curb damage. On a test drive, listen for thumping or vibration that may indicate internal tyre damage, and feel for any pull or wander that could betray uneven wear or mis‑alignment. Verify that the tyre pressure sensors are functional and that the spare (if fitted) is in good condition. Given the car’s age and low mileage, also inspect for time‑related wear: check the 12‑volt battery for cranking voltage and signs of sulphation, and consider a load test or replacement if it is older than four years. Examine the brake discs for surface rust, pitting or uneven wear that can develop when the vehicle sits for long periods, and ensure the calipers move freely without binding. Look over the suspension bushes, coil springs and anti‑roll bars for any cracking, corrosion or excessive play, especially around the front sub‑frame where age‑related fatigue can appear. Finally, confirm that the service history includes regular oil, coolant and brake fluid changes at the manufacturer‑specified intervals; if the records are missing, a full fluid flush and a comprehensive inspection of hoses and seals would be prudent before committing to purchase.
