2014 Mercedes-Benz ML 2.1L Diesel · LO63 VCX

The most recent DVSA MOT test conducted on 17 November 2025 resulted in a Pass with no defects or advisories recorded, indicating that the vehicle met the minimum roadworthiness standards at the time of inspection. Looking at the broader MOT history over the past three years, the test record shows a stable pattern with Passes achieved in late 2023, late 2024, and late 2025, interspersed with two earlier Fail entries from November 2025 and December 2024. Crucially, neither of those failures carries any recorded defects on the DVSA database, which is a relatively common occurrence when a vehicle fails on an item that is rectified and re-presented within a short timeframe, such as emissions, lighting, or a brake-related adjustment. Overall, the maintenance trend appears stable and consistent, with the vehicle successfully returning to a clean test status on each occasion following the earlier failure. The absence of recurring advisories across the most recent tests suggests that the principal wear items are being addressed before they progress into failure categories. With a recorded mileage of 116,384 miles over approximately twelve years, this Mercedes-Benz ML has covered an average of around 9,700 miles annually, which sits broadly in line with typical usage for a large premium SUV of this era. The mileage appears to be accumulating at a fairly steady, moderate rate rather than showing the extremes of very low annual use or exceptionally high motorway mileage. At this odometer reading, the mechanical implications are that the major drivetrain components, including the engine, automatic transmission, and four-wheel-drive system, are well into their working life and will have experienced considerable cumulative wear. Items such as suspension bushes, anti-roll bar links, shock absorbers, and coil springs are likely approaching the latter portion of their service life, and given the vehicle's kerb weight, brake discs and pads will have required multiple replacements already. The 3.0-litre diesel engine fitted to many ML models of this generation is also known to require attention to injectors, EGR components, and the swirl flap mechanism at higher mileages. Given the clean MOT record with no recorded advisories, particular attention should be directed toward age-related deterioration rather than specific flagged defects. Tyres should be inspected closely for sidewall perishing and cracking, as rubber compounds degrade with calendar age regardless of tread depth, and a twelve-year-old vehicle may well be running tyres that have passed MOT on tread but are compromised by age. The 12-volt battery should be tested for state of health, as batteries in vehicles of this age frequently suffer from reduced cranking performance, particularly in colder months, and Mercedes-Benz electrical systems are sensitive to voltage fluctuations. The brake calipers and discs should be examined for any signs of corrosion or seizing from standing, especially if the vehicle has spent extended periods unused, and the handbrake mechanism should be checked for full engagement and release. All fluid services, including engine oil, automatic transmission fluid, brake fluid, and coolant, should be verified against the manufacturer's service schedule, as time-based degradation occurs regardless of mileage covered. On a test drive, the buyer should listen for any suspension clonks or knocking over uneven surfaces, which would suggest worn bushes, drop links, or top mount deterioration, and pay attention to any knocking from the steering rack area on full lock. Brake feel should be assessed for pulling to either side, sponginess indicating air or moisture ingress in the hydraulic system, or shudder under heavy braking suggesting disc runout. The automatic gearbox should be observed for smooth, timely changes both warm and cold, and any hesitation, flare, or harsh engagement would warrant further investigation. The diesel engine should be started from cold and monitored for excessive smoke, irregular idle, or any unusual rattles, and a diagnostic scan would be advisable to check for stored fault codes relating to the emissions control system, particularly the DPF, EGR, and AdBlue system which are common concern areas on this generation of Mercedes-Benz diesel. A full underbody inspection on a ramp is strongly recommended to check for oil leaks, corroded brake lines, and any structural concerns, given that corrosion advisories are a common failure point on older SUVs exposed to winter road conditions.
