2014 Mercedes-Benz ML 2.1L Diesel · H18 DAD

The most recent MOT inspection on 26 November 2025 resulted in a pass, though it carried an advisory regarding front tyre wear being close to the legal limit and worn on the edges. When reviewing the longitudinal maintenance trend, the vehicle shows a recurring pattern of tyre-related advisories and a significant failure in 2022 due to an inoperative engine malfunction indicator light. While the 2024 inspection was notably clean with no defects recorded, the reappearance of tyre wear issues in late 2025 suggests that while the vehicle is being maintained to pass its annual inspections, there is a persistent need for attention regarding consumables and potentially wheel alignment. With a recorded mileage of 87,706 miles over approximately twelve years, this Mercedes-Benz ML has averaged roughly 7,300 miles per year. This represents relatively low annual usage for a premium SUV of this age, which often indicates lighter motorway use or shorter, more frequent journeys. While lower mileage can preserve certain mechanical components, it can also lead to specific issues associated with vehicles that spend significant time stationary. In this context, the mileage is consistent with a well-kept vehicle, but the owner must ensure that the lower usage has not resulted in neglected service intervals or the degradation of fluids and rubber components due to lack of thermal cycling. The MOT history reveals a consistent trend of tyre degradation, specifically regarding edge wear and perishing. The repeated advisories for tyres being worn on the edges suggest a potential issue with wheel alignment or suspension geometry. During a test drive, you should pay close attention to steering stability and listen for any uneven road noise that might indicate irregular tread wear. Furthermore, previous advisories regarding tyre cracking and perishing indicate that the rubber may be aging prematurely. You should physically inspect the sidewalls of all four tyres for any signs of dry rot or fine cracks, especially if the vehicle has been parked outdoors, as these can lead to sudden structural failure. Beyond the tyres, the 2022 failure regarding the engine malfunction indicator light (MIL) warrants close scrutiny. You should verify that the dashboard displays no warning lights and that the engine runs smoothly without hesitation or erratic idling. Given the history of brake pad advisories and the vehicle's age, it is essential to inspect the brake discs for heavy corrosion and the calipers for signs of binding, which can occur when a vehicle is driven infrequently. Additionally, because the mileage is relatively low for its age, you should check the service history to ensure that time-based maintenance, such as oil changes, brake fluid flushes, and coolant replacements, has been performed according to the manufacturer's schedule rather than solely based on mileage intervals.
