2021 Audi A5 S Line 35 TDI Mhev S-A 2.0L Diesel · WR21 VPL

A recent MOT uncovered critical front‑brake pad wear and an inoperative engine malfunction‑indicator light, both of which were rectified before a subsequent test ten days later that returned a pass, indicating that the vehicle required prompt remedial work but now satisfies the statutory minimum standards. The presence of a dangerous brake‑pad failure alongside a major engine‑MIL fault in the same inspection cycle signals that the car’s braking system and engine‑management electronics needed attention, and the rapid correction suggests the issues were addressed before the next test. At 47,571 mi for a 2021 model, the average annual accumulation is roughly 9,500 mi, which sits comfortably within typical UK usage patterns for a five‑year‑old vehicle. The mileage does not, on its own, explain the brake‑pad wear observed, as front‑disc and pad life can vary with driving style and load rather than distance alone. There are no evident gaps in the MOT record for the period shown, so the vehicle appears to have been regularly tested, providing a continuous picture of its roadworthiness over the past two years. When inspecting the brakes, verify that the front pads have been replaced to an acceptable thickness (generally above 3 mm) and that the discs show no scoring or excessive run‑out. During a test drive, feel for consistent pedal travel without a soft or spongy feel, listen for any squeal or grinding on deceleration, and watch for any pull to one side that could indicate uneven pad wear or caliper binding. A visual check of the caliper mounting bolts and brake fluid level is also prudent, ensuring there are no leaks or corrosion that could re‑introduce a safety issue. For the engine‑management system, confirm that the MIL illuminates correctly when a fault is induced (for example, by briefly disconnecting a sensor) and that it remains off under normal operation. A scan with an OBD‑II reader should return no pending or stored fault codes; any lingering codes could point to an intermittent fault not fully resolved. While driving, note any hesitation, loss of power, or irregular idle that might hint at a lingering sensor or ECU issue, and ensure the exhaust emissions are clean and the vehicle runs smoothly across the rev range.
