2018 Audi TT 1.8L Petrol · AV18 WTF

The 2018 Audi TT has maintained a consistent MOT pass record, though the most recent test on 28 October 2025—just nine months ago—revealed minor but critical tyre defects. The near- and offside front inner tyres exhibited sidewall cracking, while the nearside rear tyre had a superficial cut. These issues, though not failings, suggest a need for immediate replacement to prevent sudden tyre failure. The absence of any major advisories or structural concerns in the latest test indicates the vehicle remains roadworthy, but the tyre conditions warrant urgent attention. Previous tests show a pattern of low-severity faults, with no recurring mechanical failures beyond standard wear items. The mileage progression of 44,541 miles over eight years—approximately 5,568 miles annually—is unusually low for a vehicle of this age, particularly given the Audi TT’s typical usage patterns. The gaps between tests are regular, with consistent annual mileage increments: 30,426 miles in 2022, 36,010 in 2023, and 40,678 in 2024, culminating in 44,541 at the latest test. Such low mileage could imply either minimal usage or prolonged periods of inactivity, which may have allowed for slower accumulation of wear. However, the lack of significant mechanical faults in earlier tests suggests the vehicle has not been subjected to aggressive driving or neglect. A prospective buyer should prioritise a thorough inspection of the tyres, given the recent sidewall damage and the nearside rear cut. The 2023 and 2022 tests flagged front brake disc wear, with pitting and scoring noted in 2022, followed by excessive wear advisories in 2023. This indicates the front brake system may require attention, particularly the discs and pads, which could have degraded further over the intervening period. Additionally, the 2022 windscreen damage—though not failing—should be checked for any deterioration in visibility or structural integrity. Suspension components, including bushes and coil springs, should be examined for wear, as Audi TT models of this era are prone to bush deterioration over time. Finally, the exhaust system and underbody should be inspected for corrosion, especially around the rear axle, where moisture accumulation is common.
