2021 Audi Q3 S Line 35 TDI S-A 2.0L Diesel · FX71 WCC

The vehicle’s most recent MOT test on 12 August 2025 confirmed full roadworthiness at 28,827 miles, with no defects or advisories recorded. This represents a stable maintenance trend over the past two tests, as the previous pass on 15 August 2024 at 19,882 miles also showed no issues. The absence of recurring faults suggests the vehicle has been kept in sound condition, though the low mileage accumulation—just under 9,000 miles since the last test—means critical wear items like brakes, suspension, and fluids may not have reached their typical service intervals. The 2025 test’s clean result is reassuring, but the short interval between tests could indicate either cautious ownership or a lack of genuine wear, warranting closer scrutiny of hidden degradation. The recorded mileage of 28,827 miles over five years equates to approximately 5,765 miles annually, which is unusually low for a vehicle of this age and specification. Between the August 2024 and August 2025 tests, the car covered only 8,945 miles—a rate of just over 4,470 miles per year. Such minimal usage may imply prolonged periods of storage or infrequent driving, which can accelerate deterioration in components like seals, batteries, and fuel systems. The lack of intermediate MOT tests or service records further obscures the vehicle’s true condition, as critical wear—such as suspension bush deterioration or brake fluid degradation—could develop without proportional mileage. Given the sparse MOT history, a prospective buyer should prioritise an independent inspection of the braking system , including rear caliper binding (a common TDI issue) and disc thickness, as well as suspension integrity , particularly the rear subframe and bushings, which are prone to wear even at low mileages. The exhaust system should be checked for leaks or corrosion, especially around flanges, while the diesel particulate filter (DPF) and adblue system warrant verification, as they are often overlooked in low-mileage vehicles but can fail catastrophically if driven sporadically. Finally, the underbody and wheel arches should be inspected for corrosion, as standing water accelerates rust in critical structural areas. The absence of advisories does not preclude latent issues, so a thorough mechanical examination is essential.
