2010 Audi A5 S Line TDI Quattro S-A 3.0L Diesel · JRZ 4691

The most recent MOT on 26 February 2026 was a clean pass, and the preceding test on 10 February 2026 recorded a failure despite no specific defects being logged, suggesting an administrative or paperwork issue rather than a mechanical shortfall. The earlier passes in January 2025, August 2023 and June 2022 further reinforce a pattern of consistent compliance, indicating that the vehicle’s overall maintenance regime has remained stable over the past few years with no evident deterioration in the items inspected by the DVSA. At 187 163 miles the car has accumulated roughly 11 700 miles per annum since its 2010 registration, a usage rate that sits squarely within the normal band for a premium executive model. There are no conspicuous gaps in the mileage record that would hint at prolonged periods of inactivity, nor does the figure suggest an unusually aggressive accumulation that would accelerate wear of high‑load components such as the suspension, braking system or the quattro all‑wheel‑drive differentials. Nonetheless, the total mileage is sufficient for wear to be expected on consumables and for time‑related degradation to be a factor, particularly on rubber and fluid‑based items. A prospective buyer should give particular attention to the condition of the tyres, as the age of the rubber can exceed the safe service life even when tread depth appears adequate; look for sidewall cracking, hardening or any signs of perishing that can precipitate a sudden failure. The 12‑volt battery, now approaching 16 years, should be load‑tested and inspected for electrolyte loss or terminal corrosion, while the alternator output should be verified under load. Brake discs and pads should be examined for thinning, surface rust or uneven wear, and the calipers should be checked for any signs of sticking or fluid leakage that could cause shudder or reduced stopping performance. Because the vehicle is equipped with the quattro system, the front and rear differentials should be inspected for oil condition and any metallic particles, and the differential oil should be refreshed according to the manufacturer’s interval, typically around 100 000 miles. Given the vehicle’s age, a thorough visual inspection of the under‑body for corrosion, especially around the wheel arches, suspension mounting points and exhaust system, is essential. The suspension bushings, ball joints and coil springs should be probed for play or creaking, and a test drive should include listening for clunks over bumps and monitoring for any wandering or pull to one side that could indicate worn steering components. Finally, confirm that the service book reflects timely oil, filter and timing‑belt changes – the TDI engine’s timing belt generally requires replacement around the 100 000‑mile mark – and verify that the coolant, brake fluid and gearbox oil have been refreshed within the recommended calendar intervals, as fluid degradation can lead to overheating, corrosion or shifting irregularities even on a vehicle that has passed recent MOTs.
