2007 Audi A6 2.0L Diesel · RK57 DAN

The 2007 Audi A6’s latest MOT test on 2026-09-01 was passed, but the advisory of rear brake pads wearing thin to just 1.1mm remaining thickness (the legal minimum) indicates a critical wear progression that has not been addressed. While the preceding MOTs in 2025 and 2024 showed no defects, the 2025 test revealed persistent issues—nearside rear tyre wear close to the legal limit, front suspension arm ball joint play, and a minor exhaust leak—that suggest a pattern of recurring advisories rather than isolated incidents. This trend, combined with the thin brake pads, raises concerns about either inadequate maintenance or underlying mechanical wear that could escalate if not rectified promptly. The vehicle’s roadworthiness is currently compliant, but the advisories demand immediate attention to prevent further deterioration, particularly to braking performance and suspension integrity. The recorded mileage of 151,618 miles for a 19-year-old A6 aligns with a moderate annual usage rate of approximately 7,980 miles, which is typical for its age and likely reflects a mix of practical daily driving and occasional longer trips. However, the absence of service intervals or detailed maintenance records makes it difficult to determine whether this mileage has been accumulated gradually or if there have been extended periods of inactivity, which could contribute to standing corrosion or fluid degradation. A higher-than-expected mileage over a decade might indicate more aggressive use, accelerating wear on consumables like brake pads, suspension components, and drivetrain elements, whereas lower mileage could imply a vehicle that has been kept in a lower-traffic environment or stored for prolonged periods. Either scenario warrants careful inspection of fluid condition and component health to avoid hidden issues. To proceed with a thorough inspection, the prospective buyer should prioritise checking the rear brake system first, as the thin pads indicate significant friction material loss. Look for uneven wear patterns on the brake discs, which could signal warping or binding calipers, and listen for grinding noises when braking—this would confirm the need for immediate pad replacement. During a test drive, monitor the rear brake pedal feel for excessive sponginess or softness, which might indicate hydraulic issues or air in the system, and watch for brake pedal vibration or shuddering, which could point to warped discs or contaminated brake fluid. The nearside rear tyre’s edge wear suggests directional bias, potentially caused by misalignment or suspension imbalance; verify alignment settings and inspect for cracks or separation in the sidewall, as tyre perishing from age is a growing concern for vehicles of this vintage. For the suspension advisories, the front ball joint play is a red flag for long-term stability and steering accuracy. Inspect the ball joints for excessive play by gently pushing and pulling on the steering wheel while the vehicle is on jack stands—any noticeable movement or clunking noises during cornering or over bumps will confirm the issue. The minor exhaust leak could allow unburnt gases to backflow, affecting emissions and engine efficiency; visually inspect the exhaust system for cracks or loose connections, and listen for hissing noises when accelerating. Given the vehicle’s age and mileage, a comprehensive fluid check is essential: top off and test the engine oil for contamination or sludge, inspect the brake fluid for dark colour or bubbles, and verify the coolant level and condition, as standing fluids can degrade over time. Additionally, check the 12V battery terminals for corrosion and ensure the battery holds a charge, as older vehicles are prone to electrical issues from prolonged inactivity or age-related battery failure. Finally, examine the tyres for sidewall cracking or perishing, which can compromise structural integrity, and verify that the tread depth is well above the legal minimum to ensure safe traction.
