2019 Audi A6 2.0L Diesel · SC19 WSW

The most recent MOT test conducted on 24 June 2026 resulted in a pass, but this followed a failure on the same date involving both a dangerous defect and a lighting malfunction. The failure was due to front tyre tread depths being below the legal 1.6mm limit on both sides and an inoperative engine malfunction indicator lamp. While the vehicle was rectified and passed, the sudden shift from a clean history to a failure suggests a recent decline in maintenance standards or a tendency to run consumables to their absolute limit. The maintenance trend should be viewed as unstable, as the vehicle has moved from several years of clean passes into a period where critical safety and monitoring components were found to be deficient. With 109,240 miles recorded, this Audi A6 has covered approximately 15,600 miles per year, which is high for a seven-year-old vehicle. This level of usage implies the car has been driven extensively, likely on motorways, which is often preferable to short-trip city driving but accelerates the wear on mechanical components. At this mileage, the vehicle is entering a phase where major wear items such as suspension bushes, coil springs, dampers, and drivetrain components are more likely to require replacement. It is essential to verify that the service history is comprehensive and that all major interval-based maintenance, such as timing belt or water pump replacements, has been completed to prevent catastrophic mechanical failure. During your inspection and test drive, you must pay close attention to the engine's electronic monitoring. Since the engine malfunction indicator lamp was previously flagged as inoperative, ensure that all dashboard warning lights function correctly and that the engine runs smoothly without hesitation or irregular idling. Regarding the tyre failure, inspect the remaining tyres for uneven wear, which could indicate underlying issues with wheel alignment, worn tie-rod ends, or suspect wishbone bushes. Listen carefully for any knocking or clunking sounds from the suspension when navigating uneven surfaces, as high-mileage vehicles often exhibit wear in the bushings or dampers. Furthermore, conduct a thorough check of the braking system. Look for excessive corrosion or scoring on the brake discs and check for any signs of binding calipers or uneven pad wear. Given the high mileage, you should also inspect the vehicle for any signs of fluid leaks from the engine, gearbox, or cooling system. Check the condition of all rubber hoses and belts for cracking or perishing, and ensure the battery is holding a stable charge. A detailed review of the service book is mandatory to confirm that the high annual mileage has been supported by regular, timely oil changes and scheduled mechanical inspections.
