2006 Mercedes ML 3.0L Diesel · DF06 HXE

The vehicle currently holds a valid MOT, but the history reveals a worsening trend regarding engine and exhaust health. While it passed the most recent test in November 2025 at 183,482 miles, this followed a significant failure just four days prior. That November 2025 failure identified a major rear exhaust leak and smoke emissions exceeding limits for a turbocharged engine. The persistent presence of an oil leak across every test since at least 2023 suggests a chronic issue that the owners have opted to monitor rather than fully rectify. At 183,482 miles over 20 years, the vehicle has averaged approximately 9,174 miles per year, which is consistent with typical UK usage for its age. The data shows a recent increase in activity between March 2024 and March 2025, where the vehicle covered 4,451 miles in just 12 months. This consistent use, combined with the high total mileage, places significant stress on the drivetrain and emissions-related components, as evidenced by the recurring failures in early 2025 and late 2025. A buyer must conduct a thorough inspection of the engine bay to determine the source of the persistent oil leak, as it has been a recurring advisory for three years. The previous failures regarding smoke emissions and exhaust leaks indicate potential turbocharger wear or fuel injector issues, which require a professional diagnosis. Attention should also be paid to the braking system, as the tester noted a binding nearside front brake in 2023 and uneven tyre wear on the rear axle in 2024. Check the condition of all rubber components and suspension bushes, as the record shows a history of tyre perishing and damage that may indicate neglected preventative maintenance.
