2021 Audi S3 Tfsi Quattro S-A 2.0L Petrol · CF21 XCC

A clean and uninterrupted MOT record defines this 2021 Audi S3 TFSI Quattro S-tronic, with three consecutive passes dated 5 April 2024, 24 March 2025, and 31 March 2026, each carried out without a single advisory or failure entry. The absence of any flagged component wear, corrosion, oil leakage, suspension degradation, brake issue, or lighting defect across the testing history points to a vehicle that has remained structurally and mechanically sound through its first five years. For a prospective buyer, this is a reassuringly unblemished DVSA profile, indicating the car has not yet exhibited the typical wear patterns that begin to surface on performance saloons of this age, such as worn suspension linkages, binding calipers, or early exhaust corrosion. With 35,685 miles recorded against a five-year span, this S3 has averaged approximately 7,137 miles annually, a figure closely aligned with typical UK usage for a modern performance vehicle. There are no unusual gaps between tests, no sudden mileage jumps, and no evidence of long stationary periods that might otherwise raise concerns about dormant component deterioration such as seized brakes, perished cooling system hoses, or 12V battery degradation. The consistent year-on-year accumulation suggests the vehicle has been in regular use, which from a mechanical standpoint is generally favourable for a turbocharged petrol engine and its associated ancillaries, as frequent operation helps preserve oil quality, prevents moisture accumulation in the exhaust system, and keeps driveline seals and CV joints properly lubricated. The relatively modest mileage also means the quattro drivetrain, dual-clutch S-tronic transmission, and turbocharger have not been subjected to excessive wear. Given the clean MOT history, any inspection should now focus on the components that typically begin to demand attention on a 35,000-mile S3 of this generation, even though they have not yet triggered an advisory. On a test drive, listen for any clonking or knocking from the front suspension over uneven surfaces, particularly from the lower wishbone bushes and anti-roll bar drop links, which are known wear items on MQB-platform performance cars. Check for steering pull or vagueness, which could indicate worn front suspension geometry or tie rod ends, and feel for any vibration through the steering wheel under braking, which may suggest warped front brake discs, a common issue when S3s are driven enthusiastically and then left to sit. Inspect the brake discs and pads directly for lipping, surface corrosion, or uneven wear, and verify the calipers are releasing cleanly without any binding. Beyond the running gear, pay close attention to the visual condition of the underside, paying particular attention to the subframe mounting points, exhaust downpipes, and suspension turrets for any early signs of surface corrosion, as Audis of this era can begin to show rust in these areas before it reaches a level that would fail an MOT. Examine the engine bay for any oil misting or seepage around the cam chain cover, turbo oil feed lines, and the rear main seal area, all of which are worth monitoring as mileage accumulates. Confirm that the S-tronic gearbox changes smoothly through all ratios, especially when warm, and that there is no hesitation or shunt at low speeds, as DSG mechatronic issues can develop gradually. Finally, ensure all electronic systems, including the Virtual Cockpit, MMI infotainment, driver assistance features, and climate control, are functioning correctly, and verify that the service history includes timely DSG oil and filter changes along with haldex system servicing, as these are essential for the long-term reliability of the quattro drivetrain and should be a condition of purchase.
