2014 Audi A6 2.0L Diesel · AX14 LHM

The most recent MOT test on 2026-04-28 resulted in a clean pass, marking a positive turnaround after a series of failures and advisories spanning the previous two years. While the vehicle has not faced any major defects since 2024-06-05, the history reveals a pattern of recurring issues that suggest underlying wear and potential neglect. The 2024 test alone recorded two advisories—offside rear coil spring corrosion and nearside rear shock absorbers with reduced damping—which indicate progressive degradation in the suspension system. The 2022 failure highlighted persistent front windscreen wiper ineffectiveness and headlamp misalignment, reinforcing the need for vigilance over both mechanical and optical components. Though the latest test passed, the prior failures underscore that the vehicle’s structural and functional integrity has been compromised over time, particularly in areas prone to high stress, such as the suspension and tyres. The vehicle’s recorded mileage of 146,096 miles at the time of assessment represents a notably high annual usage rate of approximately 12,175 miles per year, which is unusually aggressive for a 12-year-old A6, particularly given the absence of long periods in storage. Such high mileage accelerates wear on critical components like suspension bushes, brake pads, tyres, and drivetrain elements, as evidenced by the MOT history. The nearside rear coil spring fracture in 2025-05-15 is a critical failure point, as coil springs are designed to absorb lateral forces and maintain ride height; a fractured spring compromises handling stability, increases stress on adjacent components, and can lead to uneven tyre wear or alignment issues. The corrosion of the offside rear coil spring and reduced damping in the nearside rear shock absorbers further suggest that the suspension has not been adequately maintained, potentially leading to premature failure of other suspension elements or even drivetrain misalignment. For the prospective buyer, the most urgent concerns stem from the suspension system, where the history indicates significant wear and potential instability. Prior to purchase, conduct a thorough inspection of the suspension geometry, focusing on the rear coil springs and shock absorbers. Listen for unusual clunking or rattling noises during acceleration, braking, and cornering, as these may signal loose suspension components or failing dampers. Visually inspect the coil springs for any signs of elongation, bulging, or physical damage, and check for uneven tyre wear patterns that could indicate misaligned suspension or binding calipers. The brake system should also be scrutinised, particularly the rear discs and pads, as the suspension failures may have contributed to uneven braking performance or binding calipers, which can lead to reduced braking efficiency or even failure under heavy load. Additionally, verify that the vehicle’s drivetrain and exhaust system are free of leaks or unusual noises, as high mileage can accelerate wear in these areas. Beyond the mechanical checks, the buyer should address the broader operational and safety aspects of the vehicle. Given the high mileage and age, pay particular attention to the condition of the tyres, as the 2023 advisories on tyre wear close to legal limits suggest that the tread depth may have been compromised. Check for sidewall perishing, which can occur from prolonged exposure to the elements or low tyre pressure, and inspect for cracks or bulges that could indicate internal damage. The battery should be tested for health, as older vehicles with high mileage are more susceptible to electrical gremlins or failure, particularly if the vehicle has been left unused for extended periods. Finally, ensure that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and free from contamination, as fluid degradation over time can exacerbate wear on engine, transmission, and suspension components. If possible, obtain a service history to confirm that scheduled maintenance, such as oil changes and fluid top-ups, has been conducted according to the manufacturer’s recommendations. For the A6’s age and mileage, a comprehensive pre-purchase inspection by a qualified mechanic is strongly advised to identify any hidden issues that may not be apparent from the MOT records alone.
