2016 Audi A6 2.0L Diesel · YY66 AHC

The most recent MOT, dated 1 August 2024, was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. This follows a period of intermittent failures in 2024, notably a missing off‑side mirror in July, an inoperative engine malfunction‑indicator lamp (MIL) and an inability to complete the emissions test in April and June. The successful outcome in August suggests that the owner has remedied those specific deficiencies, and the maintenance trend appears to be stabilising rather than deteriorating, provided no new faults have emerged since the last inspection. At 100 881 miles the 2016 Audi A6 has logged roughly 10 000 miles per annum, a usage rate that sits comfortably within the normal band for a ten‑year‑old executive saloon. The mileage record shows no large gaps that would imply prolonged periods of inactivity, nor any spikes that would point to unusually aggressive driving. Consequently the wear on consumables such as brake pads, clutch components and tyre tread is likely to be proportional to age and mileage rather than excessive, but the cumulative distance does mean that many service‑interval items will be approaching the end of their design life. When inspecting the car, verify that the off‑side exterior mirror has been correctly reinstated and that the glass is securely fitted, as a missing mirror not only contravenes regulation but can also affect driver visibility and safety. Confirm that the engine MIL is fully operational; a functional warning lamp is essential for early detection of engine faults and for compliance with emissions testing. During a test drive listen for any irregularities that could indicate lingering engine management issues – such as rough idle, hesitation on acceleration, or a noticeable loss of power – and watch the dashboard for any illuminated warning symbols. It is also prudent to have the on‑board diagnostics scanned for stored fault codes, particularly those related to the emissions system, to ensure that the catalytic converter, oxygen sensors and exhaust gas recirculation valve are functioning correctly and that no hidden faults remain. Given the vehicle’s age, independent of the MOT record, a thorough visual and tactile examination is advisable. Inspect the tyre sidewalls for cracking, dry rot or age‑related hardening, as tyres older than six years can become unsafe even if tread depth appears adequate. Examine the 12‑volt battery for signs of sulphation, swollen case or excessive electrolyte loss, and consider a load test to confirm remaining capacity. Check the brake discs for surface rust, scoring or uneven wear that could indicate binding calipers, and verify that the pads have sufficient material. Look over the suspension bushes, ball joints and coil springs for any signs of corrosion, leakage or excessive play, and ensure that the exhaust system is free of rust perforations. Finally, confirm that routine fluid services – engine oil, coolant, brake fluid and gearbox oil – have been performed at the manufacturer‑specified intervals, as time‑based degradation can lead to reduced lubrication and potential component failure even on a vehicle with moderate mileage.
