2016 Audi A6 2.0L Diesel · PL65 GCV

The most recent MOT on 26 February 2026 was passed with no recorded defects, indicating that at the time of testing the vehicle met the statutory safety and emissions requirements. Over the preceding decade the MOT record shows a pattern of isolated advisories – notably thin rear brake pads in 2025, tyre tread approaching the legal limit in 2021 and a series of plate‑mounting and under‑tray observations – but no outright failures. This suggests a generally stable maintenance regime, with the occasional wear‑related issue that has been flagged but not allowed to deteriorate to a failure point. At 135,441 miles the 2016 Audi A6 averages roughly 13,500 miles per annum, a usage rate that sits above the typical UK average for a vehicle of this age. The mileage is not excessive for a six‑cylinder executive saloon, yet it does imply accelerated wear on consumables such as brake discs, pads, suspension bushings and tyre rubber. The record of tyre tread warnings in 2021 indicates that the original tyres have likely been replaced, but the high cumulative mileage means that the remaining tread depth, sidewall integrity and uniformity should be verified. Similarly, the rear brake pad advisory in 2025 points to a wear pattern that may have progressed to the discs, so the condition of the rear discs and caliper operation warrants close inspection. When inspecting the car, give particular attention to the rear braking system. Check the pad thickness visually and feel for any pulsation or shudder when applying the brakes, especially under moderate load, as this can signal disc glazing or uneven pad wear. Examine the front and rear tyres for age‑related cracking, sidewall perishing or uneven wear that could indicate mis‑alignment, worn suspension components or incorrect tyre pressures. Listen for clunking or creaking from the front and rear suspension during cornering and over bumps, which may reveal deteriorated bushings, worn coil springs or worn anti‑roll bar links. Verify that the rear number‑plate mounting is secure and that any under‑tray panels have been correctly refitted, as loose fittings can allow road debris and moisture to reach the chassis and lead to corrosion of the under‑body and exhaust hangers. Given the vehicle’s age and mileage, also assess time‑based items that are not captured by the MOT. Inspect the 12 V battery for signs of sulfation, check the electrolyte level if it is a serviceable type and confirm that the terminals are clean; a battery that has been idle for long periods may struggle to hold charge. Examine the engine oil, coolant, brake fluid and power‑steering fluid for colour and clarity, and inquire whether a full service, including filter changes, has been performed within the last 12 months – fluids degrade with time even if the car is not driven heavily. Finally, review the service book for evidence of regular oil changes, timing‑belt or chain maintenance (if applicable) and any recorded suspension or steering component replacements, as these records will give confidence that the high annual mileage has been supported by appropriate preventative maintenance.
