2016 Audi A6 2.0L Diesel · SF66 AAW

The most recent MOT test on the 2016 Audi A6, conducted on 2025-01-29, resulted in a passing grade, though it revealed persistent issues with the front suspension components. While the vehicle did not fail this test, the advisories and minor failures indicate a pattern of wear that has not been fully addressed. The near-side front lower suspension arm ball joint exhibited slight play and a severely deteriorated dust cover, suggesting ongoing mechanical fatigue in the joint assembly. Additionally, the offside front upper suspension arm pin or bush showed signs of wear but was deemed not excessive at the time. These findings contrast sharply with the previous MOT failure in 2024-08-01, where the near-side front outer drive shaft constant velocity (CV) joint boot was detached, a major defect that would have rendered the vehicle unsafe without immediate repair. The absence of further failures since 2024-08-01 suggests either effective corrective action or a temporary reprieve, but the suspension advisories warrant careful monitoring to prevent progressive deterioration. The recorded mileage of 215,367 miles for a ten-year-old vehicle represents a high annual usage rate of approximately 21,537 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on critical components like suspension bushes, CV joints, brake systems, and drivetrain elements, as evidenced by the MOT history. The rapid mileage suggests either heavy daily use or periods of prolonged driving, both of which increase stress on mechanical systems. The absence of significant gaps in the MOT schedule—particularly the failure in 2024-08-01—may indicate that the vehicle has been driven consistently rather than left stationary for extended periods, which could otherwise exacerbate issues like standing corrosion or fluid degradation. However, the high mileage alone does not explain the specific wear patterns observed, such as the CV joint boot failure or suspension arm joint deterioration, which likely stem from cumulative mechanical stress rather than just distance traveled. For the prospective buyer, the most critical areas to inspect are the front suspension and drive train components, given the recurring advisories and failure. The near-side front lower suspension arm ball joint’s play and deteriorated dust cover suggest that the joint may be nearing end-of-life, and further wear could lead to excessive movement, clunking noises during cornering or over bumps, or even complete failure with potential steering instability. The offside upper suspension arm pin or bush should also be checked for increased play or grinding noises, as wear in this area could compromise ride quality and handling. The CV joint boot failure from 2024-08-01 is particularly concerning; the CV joint itself may have been replaced, but the boot’s condition should be verified to ensure it is fully secure and intact. Listen for unusual clunking or rattling noises in the front suspension during a test drive, particularly when accelerating or braking, as these could indicate loose or worn components. Additionally, inspect the front wheels for uneven tyre wear patterns, which may suggest misalignment or suspension issues. Beyond the suspension and drive train, the tyre history is relatively benign, with only a minor cut on the near-side rear tyre recorded in 2023-04-12 that did not reach the ply or cords. However, given the vehicle’s age and high mileage, the tyres should be thoroughly examined for signs of excessive wear, sidewall cracking, or perishing, which can compromise safety and structural integrity. Check the tread depth across all tyres, ensuring they meet the legal minimum of 1.6mm, and verify that the wear is uniform. The tyres should also be rotated if not already done to extend their lifespan. The brake system should be inspected for signs of corrosion or binding calipers, particularly on the near-side front where standing may have contributed to rust. Listen for grinding noises during braking, which could indicate worn brake pads or metal-on-metal contact, and check for uneven brake disc wear or warping. The battery should be tested for voltage and charge capacity, as the high mileage and potential prolonged periods of inactivity could affect its health. Finally, given the vehicle’s age, the oil and other fluids should be checked for degradation or contamination, with a recommendation to replace them if they are more than 5–10 years old, even if they appear serviceable. Service records should be reviewed to confirm that routine maintenance, such as timing belt replacement (if applicable) and fluid servicing, has been conducted as specified in the manufacturer’s schedule.
