2014 Audi A6 2.0L Diesel · WM14 AAE

The 2014 Audi A6’s latest MOT test on 2025-12-12 was passed with no recorded defects, but the overall maintenance trend over the past three years shows a pattern of persistent advisories rather than outright failures. While the vehicle has not failed an MOT since 2022, the recurring advisories—particularly around tyre wear and minor engine mounting issues—suggest a gradual accumulation of wear that has not yet reached critical levels but warrants ongoing attention. The 2023 test highlighted an oil leak and significant tyre wear close to legal limits, while the 2024 test confirmed continued tyre edge wear across all tyres, indicating either aggressive driving habits or excessive cornering forces. These advisories, when combined with the high recorded mileage, imply that the vehicle has been subjected to regular, potentially demanding use, which has led to wear on consumables and suspension components. The recorded mileage of 190,156 miles for a vehicle aged approximately 12 years represents an annual average of around 15,846 miles, which is notably high for its age. Such mileage accumulation typically accelerates wear on critical components such as brakes, suspension bushes, coil springs, and drivetrain elements, as well as consumables like brake pads, oil, and coolant. The lack of significant mileage gaps suggests consistent use, which may have contributed to the observed tyre wear patterns and minor engine mounting wear. However, the high mileage also raises concerns about potential long-term stress on the engine mounts, transmission, and exhaust system, as these components are particularly susceptible to fatigue and failure with prolonged, high-mileage exposure. To proceed with a thorough inspection, the prospective buyer should prioritise checking the tyre condition beyond the legal limits, as the advisories from previous MOTs indicate edge wear and potential uneven distribution. Look for signs of tyre perishing or cracking in the sidewall, which can weaken the tyre structure and pose a safety risk, especially given the vehicle’s age. During a test drive, monitor for uneven tyre wear patterns, which may suggest misalignment, suspension issues, or incorrect tyre pressures. Listen for unusual noises from the front or rear suspension, such as clunks or rattles, which could indicate worn suspension bushes, broken coil springs, or loose suspension components. Inspect the engine bay for oil leaks, particularly around the oil pan, oil filter housing, and valve cover, as the 2023 MOT advisory suggests ongoing oil consumption or leakage that may require attention. Additionally, the buyer should verify the condition of the front lower engine mounts, as the 2023 MOT advisory noted slight wear. During a test drive, pay attention to any excessive vibration or noise from the engine area, which could indicate failing mounts or other engine-related issues. Check the brake system for signs of corrosion on the discs or binding calipers, especially if the vehicle has been stationary for prolonged periods, as standing brakes can lead to rust and reduced braking efficiency. Inspect the coolant and oil levels, as well as their condition, to ensure they are within specification and not degraded by age. Given the vehicle’s mileage, a full service history check is advisable to confirm the last oil change, filter replacement, and fluid top-ups, as these are critical for maintaining engine and transmission health. Finally, test the battery voltage and clean the terminals to ensure adequate power delivery, particularly if the vehicle has been used in colder climates or left unused for extended periods.
