2015 Audi A8 3.0L Diesel · YA65 KBK

The most recent DVSA MOT test on the 2015 Audi A8 was conducted on 2026-06-08, resulting in a pass. While the vehicle’s MOT history shows a pattern of passing tests with only minor advisories, there is a notable recurrence of wear-related issues, particularly concerning the front and rear tyres, suspension components, and brakes. The advisories from the last two MOTs—front tyre wear close to the legal limit and inner suspension arm pin or bush wear—suggest that the vehicle has experienced consistent, if not accelerating, wear progression over the past year. This trend, combined with the failure in 2021 highlighting severe rear brake pad wear, indicates that while the car remains roadworthy, the owner should be proactive about addressing these recurring concerns to prevent further deterioration or potential failures. The recorded mileage of 174,293 miles for a vehicle aged approximately 11 years represents a high annual usage rate of around 15,845 miles per year, which is significantly above the average for its class. Such mileage accumulation typically accelerates wear on critical components like tyres, brakes, suspension bushes, and drivetrain elements, as evidenced by the MOT history. The absence of major gaps between tests suggests the vehicle is in regular use, likely under demanding conditions, which may have contributed to the observed tyre and brake wear. Additionally, the high mileage could mean that fluid degradation, such as brake fluid or differential fluid, may be more pronounced, warranting closer attention to their condition and replacement intervals. For a prospective buyer, the most pressing concerns stem from the recurring tyre and brake advisories. The front tyres show wear close to the legal limit, with edge wear indicating possible misalignment or incorrect tyre pressure, which should be checked and addressed to prevent further uneven wear or hydroplaning risks. The rear tyres have multiple advisories, including cuts and significant wear, which could compromise traction and handling, especially in wet conditions. On a test drive, listen for uneven tyre noise, check for excessive vibration or pulling to one side, and inspect for signs of hydroplaning or skidding. The rear brake pads were worn down to the wear indicator in 2021, and while the discs are only moderately worn, the persistent thinness of the pads suggests they may need replacement soon. Listen for a grinding noise when braking, which could indicate metal-to-metal contact if pads are severely worn, and check for brake pedal softness or pulsation, which may signal warped discs or binding calipers. Beyond the immediate concerns, the vehicle’s high mileage and regular use necessitate a thorough inspection of the suspension system. The advisories on front suspension arm pin or bush wear imply that the control arms may require lubrication or replacement, as excessive movement could lead to further damage or reduced handling stability. Inspect the suspension for clunks or rattles when driving over bumps, and check for uneven spring compression or sagging, which could indicate spring failure. Additionally, given the vehicle’s age and mileage, the 12V battery should be tested for capacity and corrosion on the terminals, as standing or prolonged use can accelerate battery degradation. The engine oil, differential fluid, and coolant should be checked for contamination or degradation, with a recommendation to replace them if they are beyond their recommended service intervals—typically every 60,000 to 100,000 miles or every 2 to 5 years, depending on the fluid type. Finally, the exhaust emissions system should be inspected for leaks or blockages, as the Audi A8’s catalytic converter and oxygen sensors are prone to failure with high mileage. A visual check for rust or damage to the exhaust manifold and sensors, along with a scan tool readout for error codes, would be prudent.
