2021 Audi S3 Tfsi Quattro S-A 2.0L Petrol · NG21 XNL

The 2021 Audi S3 Quattro presents a clean MOT record in its most recent test, with no defects recorded during the July 2025 inspection at 42,468 miles—despite an initial failure the day prior, also at the same mileage. This suggests a stable maintenance trend, as the vehicle passed without advisories or faults in both the 2024 and 2025 tests, indicating no recurring mechanical or structural issues. The back-to-back tests in July 2025, however, are unusual and may imply a pre-purchase or compliance check rather than genuine wear concerns. The absence of advisories or defects across three consecutive MOTs points to consistent upkeep, though the lack of recorded mileage between the 2024 and 2025 tests (a gap of roughly 5,000 miles over 12 months) could reflect either light use or an error in logging. The mileage accumulation of 42,468 miles over five years aligns closely with typical usage for a vehicle of this age, averaging around 8,500 miles annually—a figure that suggests neither excessive wear nor neglect. The most recent MOT at 42,468 miles was conducted just ten months ago, meaning the next test is due in July 2026, providing a relatively short window before the next official inspection. The consistency in mileage increments (4,998 miles between the 2024 and 2025 tests) further supports the idea of steady, moderate usage, though the absence of intermediate service records leaves some uncertainty about oil changes, fluid top-ups, or suspension checks. For a buyer, the primary focus should lie on verifying the vehicle’s structural integrity and hidden wear, given the sparse MOT history. While no defects were recorded, a thorough inspection of the suspension components—such as coil springs, anti-roll bars, and bushings—is advisable, as Audi’s Quattro system places significant stress on these parts. The brake system, including calipers, discs, and pads, should also be checked for uneven wear or corrosion, particularly if the vehicle has been driven in urban or wet conditions. Exhaust emissions and the DPF (if fitted) may warrant attention, though the clean MOT history suggests no immediate concerns. Finally, a review of the service history for evidence of regular maintenance—especially oil changes and brake fluid renewal—would provide greater confidence in the vehicle’s long-term reliability.
