2011 Mercedes-Benz ML 3.0L Diesel · SK11 AJK

The vehicle most recently passed its MOT in February 2025, but the overall maintenance trend appears to be declining. While the car has consistently achieved passes, the volume and severity of advisories have increased significantly in the latest report. The emergence of structural corrosion and multiple wear-related items suggests a shift from preventative maintenance to a reactive approach, indicating that several key components are now reaching the end of their serviceable life. With a recorded mileage of 171,468 miles over fifteen years, the vehicle has averaged approximately 11,431 miles per annum. This is considered typical usage for a premium SUV of this vintage. However, at this mileage threshold, the buyer must anticipate significant wear on high-stress components. The drivetrain, suspension bushings, and engine seals are likely experiencing fatigue consistent with long-term use, necessitating a more rigorous inspection of the chassis and mechanical aggregates than would be required for a lower-mileage example. Particular attention must be paid to the recurring oil leak noted since 2024, which suggests a persistent seal or gasket failure that has not been fully rectified. During a test drive, listen for any drivetrain vibrations or thumps, as the previous advisories regarding the prop shaft flexible coupling and the nearside front CV boot indicate potential wear in the transmission system. The mention of rear tyres worn on the edges is a critical indicator of poor wheel alignment or perished suspension bushes; inspect the tyre treads for scalloping or uneven wear and listen for clunks or knocks when navigating uneven road surfaces. The reported corrosion on the rear sub-frame is a point of concern and requires a thorough physical inspection to ensure the structural integrity has not been compromised. Check for heavy scaling or flaking metal in the rear chassis area. Additionally, as the front brake pads were noted as wearing thin in early 2025, verify if they have since been replaced by checking for brake disc lip wear or feeling for any shudder through the pedal during deceleration. Given the age and mileage, a full review of the service history is essential to confirm that calendar-based fluid changes and critical engine maintenance have been performed.
