2007 Audi A6 2.0L Diesel · OV57 SVR

The most recent MOT test on 2025-12-11 returned a passing result, though it was accompanied by several persistent advisories that indicate ongoing wear and potential long-term concerns in the vehicle’s suspension and corrosion systems. Comparing this to the prior MOT failure in 2025-12-08, where a major defect was found in the near-side rear coil spring, the current test shows a notable improvement, though the advisories on suspension arm bushings and rear axle corrosion remain unresolved. The earlier failure also highlighted a severely reduced headlamp intensity, which was not repeated in the latest test, suggesting either a temporary fix or a less critical issue. However, the pattern of recurring advisories—particularly on suspension components and corrosion—demonstrates a maintenance trend that has not fully resolved, with the vehicle’s structural and mechanical integrity requiring closer attention moving forward. The vehicle’s recorded mileage of 129,950 miles at 19 years old represents a moderate annual usage rate of approximately 6,839 miles per year, which is within the expected range for its age and class. This level of mileage does not suggest either excessive wear from high usage or prolonged idling, which could accelerate corrosion or fluid degradation. However, the gaps between MOT tests—particularly the two-year interval between 2023 and 2025—could imply periods of either low activity or improper maintenance, potentially contributing to the observed wear patterns. The suspension and drivetrain components, which have been flagged multiple times, are particularly sensitive to both movement and environmental exposure, making consistent servicing and inspection critical to prevent further deterioration. Given the recurring advisories on suspension arm bushings, coil springs, and rear axle corrosion, the prospective buyer should conduct a thorough inspection of the suspension system during a test drive. Listen for unusual clunking noises from the front and rear suspension, particularly when negotiating bumps or at speed, as this may indicate excessive movement in the upper or lower arms. Inspect the coil springs for any signs of sagging or further fracture risk, and check for uneven tyre wear patterns, which could correlate with misaligned suspension geometry or binding calipers. Additionally, visually inspect the rear axle area for any signs of oil leaks or further corrosion, as the heavy corrosion advisories suggest long-term exposure to moisture and salt. If the suspension components are replaced, ensure the new bushes and pins are correctly fitted and sealed to prevent future wear. For the brake system, which has also been flagged with minor issues, examine the brake discs for signs of warping, scoring, or excessive thickness reduction, and check the brake hoses for any cracks or brittleness that could lead to fluid loss or hydraulic failure. The presence of thin brake pads may warrant a closer inspection of pad thickness and pad-to-disc clearance, as well as the condition of the brake fluid reservoir to ensure it is free of contamination or moisture. Given the vehicle’s age, the buyer should also verify the condition of the 12V battery, checking for corrosion on terminals and ensuring it holds a charge without excessive strain during operation. Lastly, since the vehicle has not undergone a full service in several years, consider checking the fluid levels in the engine, transmission, and differential, and replacing any fluids that have degraded over time, particularly those exposed to prolonged periods of disuse. For tyre condition, inspect the sidewalls for signs of cracking or perishing, which can compromise structural integrity, and ensure the tread depth meets legal requirements, even if the mileage suggests it may not be heavily worn.
