2017 Audi TT 1.8L Petrol · MJ67 KLS

The most recent MOT test on 2026-06-25 resulted in a clean pass, though it included two critical advisories regarding tyre wear on both the near-side front inner and off-side rear inner tyres, each approaching the legal limit at the inner edge. While this is not a failure, it indicates a pattern of excessive tyre wear that, if unaddressed, could compromise traction, especially in wet or adverse conditions, and may signal underlying alignment or suspension issues. Comparing this to previous MOT results, the vehicle’s maintenance history is stable rather than deteriorating, with no failures beyond the rear brake pads in 2023-01-05, which were deemed dangerous but rectified. The absence of repeated failures or severe advisories suggests that the owner has generally maintained the vehicle’s roadworthiness, though the tyre wear advisories warrant closer attention to prevent further degradation. The recorded mileage of 38,945 miles for a vehicle aged nine years represents a remarkably low annual usage rate of approximately 4,327 miles per year, which is unusually low for a car of this age and model. Such low mileage often correlates with periods of prolonged stationary use, particularly if the vehicle was parked in a garage or climate-controlled environment, which can mitigate some wear but also contribute to issues like tyre perishing, battery degradation, and fluid ageing. Conversely, if the vehicle was driven infrequently but not stored properly, it may have suffered from standing corrosion on components such as the brake discs, suspension linkages, or exhaust system, where moisture and lack of movement accelerate rust formation. The discrepancy between the vehicle’s age and mileage underscores the need for a thorough inspection to rule out hidden wear from static conditions, as this could lead to unexpected failures or reduced reliability down the line. Given the advisories on tyre wear, the prospective buyer should conduct a meticulous visual and hands-on inspection of the tyres, focusing on the inner edges and shoulders for signs of dry rot, cracking, or separation, which could compromise structural integrity and safety. The near-side front and off-side rear tyres should be checked for uneven wear patterns that may indicate misalignment, incorrect tyre pressures, or suspension component failure. During a test drive, listen for unusual noises such as clunking from the front suspension, which could signal worn coil springs, suspension bushes, or binding strut mounts, all of which contribute to tyre wear. Additionally, inspect the rear brake system for any signs of excessive heat discolouration on the discs or a reduction in pad thickness beyond the 1.5 mm minimum, as the 2023 failure suggests this may be a recurring concern. For a vehicle of this age and mileage profile, the buyer should also verify the condition of the 12V battery, as prolonged disuse can lead to sulphation or terminal corrosion, reducing its capacity and requiring replacement before failure. Check the brake discs for corrosion, warping, or binding calipers, which are common issues when a vehicle stands for extended periods without braking activity. Inspect the exhaust system for leaks, rust, or structural integrity, particularly around the catalytic converter and tailpipe, as standing can accelerate corrosion. Fluid levels—particularly the engine oil, coolant, and brake fluid—should be checked for degradation, as fluids break down over time even when not in use, and should be replaced according to manufacturer recommendations, typically every 2–3 years for coolant and brake fluid. Finally, verify that the service history is up to date, with stamps for oil changes, filter replacements, and timing belt/chain servicing, as these are critical for long-term reliability, especially given the vehicle’s age. If any of these checks reveal issues, prioritise addressing them promptly to prevent escalation into costly repairs.
