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

The 2021 Audi S3 Quattro has demonstrated a clean and stable roadworthiness record over the past two MOT tests, with both inspections—most recently on 24 March 2026 at 33,304 miles and again on 11 March 2025 at 26,802 miles —resulting in a full pass with no advisories or defects. This consistency suggests the vehicle has been well maintained in terms of core mechanical and safety-critical components, with no signs of recurring issues that might indicate neglect or progressive wear. The absence of even minor advisories in both tests is particularly notable for a performance-oriented model like the S3, where suspension, braking, and drivetrain components often demand more frequent attention than average cars. That said, the short interval between tests—just under a year—means the next MOT is due soon, and buyers should verify whether the vehicle has been driven beyond the 12-month limit, which could void insurance or lead to enforcement action. The mileage accumulation of 6,661 miles per year aligns closely with the typical usage for a five-year-old car, neither excessively low nor unusually high. The gap between the two recorded MOTs— 6,502 miles over roughly 12 months —further supports this, indicating steady but not aggressive driving. There are no red flags in the mileage pattern to suggest prolonged periods of disuse or sudden spikes in activity, which could otherwise point to potential issues like seized bearings, degraded fluids, or uneven tyre wear. The lack of historical data beyond these two tests means there’s no way to confirm whether earlier owners adhered to Audi’s recommended service intervals, but the current record offers no cause for concern on that front. For a prospective buyer, the absence of MOT defects does not eliminate the need for a thorough pre-purchase inspection, particularly given the S3’s high-performance nature. Key areas to scrutinise include the suspension geometry and bushings , which are prone to wear under dynamic cornering loads, as well as the brake system —check for uneven disc thickness, binding calipers, or fluid leaks, which can escalate quickly in sporty models. The exhaust system should be examined for signs of corrosion or leaks, especially near the catalytic converter, while the underbody and wheel arches warrant close inspection for structural rust, given the Quattro’s elevated ground clearance. Finally, verify the service history for evidence of timely oil changes, differential fluid refreshes, and tyre rotations, as these are critical to preserving the drivetrain and handling precision of a car like this. The clean MOT record is a strong starting point, but performance cars often hide issues that aren’t caught by basic compliance tests.
