2012 Mercedes-Benz ML 3.0L Diesel · EN12 AVB

A recurring pattern of tyre deterioration dominates the MOT record, with multiple advisories for cuts, side‑wall damage and worn edges culminating in a dangerous failure for the off‑side front tyre on the most recent test (07 July 2026). Earlier that same day the vehicle also recorded a pass, indicating that the remaining tyres met the legal minimum at the time of inspection, but the presence of a ply‑exposed front tyre signals an imminent safety issue that must be addressed before the vehicle is driven on public roads. At 81,434 mi after 14 years the annual mileage averages roughly 5,800 mi, a figure well below typical usage for a mid‑size SUV. Such low utilisation often points to periods of limited use or storage, yet the tyre condition has deteriorated markedly despite the modest mileage, suggesting age‑related rubber hardening, possible uneven wear from infrequent rotation, or prolonged exposure to the elements. The mileage itself does not imply excessive wear on drivetrain components, but the age of the vehicle means that wear items such as suspension bushings, engine mounts and brake pads may be approaching the end of their service life and should be inspected. The tyre history alone mandates a full replacement set, with particular attention to the off‑side front tyre that exhibited exposed cords and any sidewalls showing cuts or cracking. During a test drive feel for vibrations, especially at higher speeds, and listen for thumping that could indicate internal damage. The 2024 failure recorded a non‑functional engine MIL indicator and a door that could not be opened from the outside; both issues require immediate attention. A diagnostic scan should verify the status of the engine control unit and any fault codes, while the door latch mechanism and associated wiring need functional testing to ensure safe egress. Beyond the tyre and electronic concerns, a comprehensive road‑worthiness check should include a visual inspection of suspension components for cracked or leaking bushings, a feel for any looseness in the steering column, and a brake pedal assessment for judder or sponginess. Verify that all doors operate smoothly, that there is no unusual squeak from the chassis, and that the exhaust is free of excessive smoke or rattles. Confirm that the vehicle runs without warning lights and that the steering remains centred without pull, as these observations will round out the assessment of a vehicle that, despite low mileage, shows clear signs of age‑related wear and safety‑critical tyre issues.
