2011 Mercedes-Benz ML 3.0L Diesel · WF61 FHC

The vehicle remains technically roadworthy but the maintenance history reveals a worsening trend in mechanical neglect and deferred repairs. The most recent test in November 2025 at 176,071 miles flagged several critical issues including a severely deteriorated nearside CV boot and thinning brake components. While the car consistently passes, the persistence of recurring faults like engine oil leaks and brake pipe corrosion suggests that previous owners performed only the bare minimum required to pass the MOT rather than proactive preventative maintenance. The mileage pattern is consistent with a 15-year-old vehicle, averaging approximately 11,700 miles per year. Between October 2022 and November 2024, the vehicle covered 25,549 miles, indicating steady annual use. However, the gap between the October 2023 failure and the November 2023 pass shows a rapid burst of 305 miles used to rectify missing wheel fixings and dangerous tyre damage. This highlights a period where basic safety-critical items were overlooked or ignored between annual inspections. A buyer must conduct a thorough inspection of the braking system and chassis integrity. The rear brake pipes have been noted as corroded since at least 2022, and this condition persists despite multiple years of testing, which poses a high risk of future line failure. The front brake pads and discs were flagged as dangerously thin and pitted in both 2024 and 2025, suggesting the system is nearing total exhaustion. Furthermore, the severely deteriorated front CV boot requires immediate replacement to prevent grease loss and driveshaft failure, which would lead to a significantly more expensive repair. The engine bay requires close attention to oil leaks which have been recorded annually since 2022. While the 2025 tester described the leak as not excessive, the longevity of the issue indicates aging seals or gasket failure. The recurring reports of damaged reflectors and cracked tyres further support a vehicle that has been treated with low aesthetic and mechanical care. Attention should be paid to the structural state around the fuel tank and the condition of the suspension components to ensure the high mileage has not caused significant structural fatigue.
