2015 Audi A4 Technik TDI 2.0L Heavy oil · M6 WUA

The most recent MOT, carried out on 12 September 2025, was passed with no recorded defects, and the preceding twelve‑month test in October 2024 also passed without comment. The only anomaly in the record is the failed MOT on 26 September 2024, which listed no defects; this is almost certainly an administrative failure rather than a mechanical one. Overall the MOT history shows a consistently clean sheet of results, indicating that the vehicle has been maintained to a level that satisfies the statutory safety and emissions standards and that there is no evident trend of deteriorating condition. With 70,474 miles recorded on a 2015 model, the car averages roughly 6,400 miles per year, which sits comfortably within the typical UK usage pattern for a vehicle of its age. The mileage is modest rather than excessive, suggesting that the engine, gearbox and major drivetrain components have not been subjected to high‑stress, high‑kilometre wear. However, the relatively low annual run‑off can also imply periods of prolonged standing, which can accelerate age‑related issues such as battery sulphation, tyre rubber perishing and corrosion of brake components. For a buyer, the first visual inspection should focus on the condition of the tyres: verify that the tread depth meets the legal minimum of 1.6 mm, look for sidewall cracking, bulges or dry rot that are common after a decade on the road regardless of mileage. Inspect the wheels for rust, especially around the spokes and hub bore, and ensure the wheel nuts are correctly torqued. The 12‑volt battery, now eleven years old, should be tested for cranking amperage and checked for any signs of leakage or terminal corrosion; a weak or failing battery is a typical age‑related failure. Examine the under‑body for any signs of rust or corrosion on the chassis rails, suspension mounting points and exhaust system, as standing periods can promote surface rust that may progress if left unchecked. Mechanically, a thorough test drive is essential. Listen for any clunking or squeaking from the front and rear suspension, which could indicate worn bushings, deteriorated coil springs or loose anti‑roll bar links. Pay attention to the steering feel for any play or judder that might point to worn tie‑rod ends or a deteriorating steering rack. While braking, note any pulsation, noise or a spongy pedal, which would suggest brake disc surface corrosion, glazed pads or a binding caliper that may need resurfacing or replacement. Finally, verify that the service book is up‑to‑date, with oil and filter changes, timing‑belt (or chain) service, and coolant flushes recorded at the recommended intervals; any lapses in these time‑based services should be addressed promptly to preserve the engine’s long‑term reliability.
