2020 Audi A3 S Line Edition 1 35 TDI S-A 2.0L Diesel · L44 FAY

The vehicle’s most recent MOT test on 2025-10-16 at 39,793 miles passed without defects, confirming current roadworthiness. However, the history reveals a concerning pattern of repeated failures—specifically, two consecutive MOT failures in early 2025 and early 2024, both at similar mileage intervals (32,828 and 23,585 miles respectively). While the testers did not record defects in these failures, the repeated retests suggest underlying issues were not resolved between tests, or the vehicle was not driven to the test centre in a fully compliant state. The most recent pass in February 2025 at 33,025 miles indicates the vehicle was eventually brought into compliance, but the gap between failures—just 187 miles—implies either a rushed repair or a recurring problem that was not properly addressed. The mileage progression shows an average of roughly 6,600 miles per year, which is typical for a vehicle of this age. However, the rapid accumulation between failures—particularly the 23,585-mile test in January 2024 followed by a failure at 23,828 miles just 26 days later—suggests either aggressive driving or a delay in addressing pre-existing issues. The 18-month gap between the 2024 and 2025 tests (23,823 to 33,025 miles) is unusually long for a used vehicle, raising questions about whether the car was stored or driven inconsistently during that period. There is no evidence of excessive wear from high mileage, but the lack of intermediate servicing records is notable. Given the repeated MOT failures without recorded defects, a buyer should prioritise an independent inspection of high-wear components that often cause test failures without obvious external signs. Focus on the suspension system—particularly the rear suspension bushes and coil springs—for excessive play or corrosion, as these are common causes of binding or uneven wear that may not be visible without a thorough lift inspection. The braking system should be scrutinised for uneven disc thickness, warping, or binding calipers, especially if the vehicle exhibits uneven braking or pulling. Additionally, check for corrosion at wheel arches, sills, and subframe mounts, as these areas often develop hidden rust that compromises structural integrity. The absence of recorded defects in failures suggests the issues may be subtle—such as minor fluid leaks or sensor malfunctions—but they could escalate if neglected.
