2014 Mercedes-Benz ML 2.1L Diesel · WS 123

The most recent DVSA examination on 3 October 2025 resulted in a clean pass with no advisories or defects recorded, which represents the strongest possible outcome at the latest test. Looking at the five-year trajectory, the pattern is broadly encouraging. The vehicle passed each annual test without failure, and while advisories were noted in 2022 (both front tyres worn close to legal limit and on edge) and 2024 (a nearside rear tyre showing similar wear characteristics), each was addressed and did not reappear in subsequent tests. The fact that the 2025 pass is entirely clear of advisories suggests either replacement of the worn tyres or improved rotation and alignment. Overall, the maintenance trend reads as stable with no deterioration in structural integrity, emissions, or braking performance. With 82,718 miles recorded over approximately twelve years, the vehicle has covered around 6,893 miles annually, which is broadly typical for a large premium SUV of this vintage. There are no obvious large gaps in the MOT record that would suggest extended standing, nor any indication of rapid mileage accumulation that might point to heavy commercial or motorway use. This average usage profile is generally favourable for long-term mechanical health, as it indicates regular operation sufficient to keep seals, brakes, and drivetrain components functioning normally, while avoiding the accelerated wear associated with high annual mileage. The mileage consistency also supports the assumption that service intervals have been observed reasonably. Given the age of the vehicle and the tyre-related advisories recorded in previous years, prospective buyers should pay particular attention to the current set of tyres. Even though none were flagged at the most recent test, edge wear on a heavy four-wheel-drive vehicle such as the ML frequently points to suspension geometry issues, worn bushes, or alignment concerns. On a test drive, listen for clonking or knocking from the front and rear suspension over uneven surfaces, as the ML is known for wear in the lower control arm bushes and anti-roll bar links. Uneven or inner-edge tyre wear on any new tyres fitted since the 2025 test would warrant a four-wheel alignment check and a thorough inspection of the coil springs and shock absorbers for any signs of fluid leakage or corrosion. The brake discs and calipers should also be examined, as a vehicle of this age and weight is prone to corroded disc surfaces and binding calipers, particularly after periods of wet weather standing. Beyond the recorded advisories, a twelve-year-old ML with average mileage warrants several age-related checks that MOT testing does not fully cover. The 12V battery, often a hidden cost on Mercedes-Benz vehicles, should be load-tested as it is likely approaching the end of its service life. Brake fluid should be inspected for moisture content, as it should ideally be renewed every two years regardless of mileage, and the coolant and automatic transmission fluid should likewise be checked against the manufacturer's calendar-based service schedule. Underneath the vehicle, look for any signs of oil leakage from the OM642 diesel engine's oil cooler and turbo plumbing, and inspect the air suspension components if fitted, as these are a known weakness on the ML-Class. Finally, verify a complete main dealer or specialist service history with stamps at the correct intervals, paying particular attention to the timing chain service, AdBlue system maintenance on diesel variants, and recent replacement of any perished rubber components.
