2023 Audi RS 3 Vorsprung Tfsi Quattro SA 2.5L Petrol · 6 OXW

An emission‑system fault is the only recorded failure on this RS 3, with the lambda sensor reading out of limits during the 2023‑05‑21 test, but the car cleared the MOT on 2026‑06‑03, albeit with a tyre‑cut advisory, indicating that the specific emissions issue was addressed between tests while the tyre condition remains marginal. At just 16,491 mi after roughly three years, the annual accumulation averages about 5,500 mi, well below the typical usage for a performance hatchback. The low mileage suggests limited wear on high‑stress components such as the clutch, brakes and suspension, yet it may also imply periods of inactivity that can accelerate degradation of rubber seals, hoses and tyre sidewalls. The close spacing of the two MOT entries—failure followed by a pass within two weeks—shows the vehicle was promptly retested after remedial work, leaving no significant testing gaps. The lambda‑sensor failure should be probed on a test drive by watching for a illuminated check‑engine light, listening for any irregular exhaust notes, and, if possible, scanning for stored fault codes that could point to a faulty sensor, wiring harness issues or exhaust leaks affecting the oxygen‑reading circuit. The near‑side rear outer tyre, noted as having a cut, warrants a visual and tactile inspection of the sidewall for any progression toward the ply; any signs of bulging, cracking or loss of structural integrity mean the tyre should be replaced promptly to avoid a sudden failure at speed. Given the vehicle’s age and low mileage, a comprehensive pre‑purchase inspection should also include a check of suspension bushes, tyre wear patterns, brake pads and discs for any age‑related hardening, and the condition of rubber components such as engine mounts and coolant hoses. Confirm that the exhaust system is free of cracks or corrosion and that the OBD‑II system reports no pending emissions faults before finalising the purchase.
