2004 Mercedes-Benz ML 2.7L Diesel · EK54 EEV

The vehicle's most recent DVSA MOT examination, conducted on 9 January 2026, resulted in a pass with no defects or advisories recorded, which is the most favourable outcome possible on the official roadworthiness assessment. Reviewing the broader test history reveals a pattern that is broadly stable, with passes recorded on 23 November 2023 and 21 November 2024, alongside two further test entries on 21 November 2024 and 16 November 2023 that resulted in failures. Notably, none of these tests carry any recorded defect details, advisory notes, or category items, meaning the reasons for the failures are not documented in the DVSA history. This is unusual but does occur when vehicles are presented in an unroadworthy condition (for example, with no insurance or during re-tests where prior defects have been rectified). From a buyer perspective, the absence of any recorded advisories on the passes is positive, but it is prudent to question the seller directly about the circumstances of the two failures and to satisfy yourself that any underlying issues have been properly resolved rather than simply re-presented. The recorded mileage of 100,434 miles on a 22-year-old vehicle equates to an average of approximately 4,565 miles per annum, which is considerably below the typical usage rate for a vehicle of this age and is classed as low mileage. Such a figure often indicates either genuinely light use, extended periods of standing, or a combination of both. Mechanically, low annual mileage is a double-edged sword: while components such as the engine, transmission, and clutch may have experienced less wear, prolonged standing periods introduce their own characteristic problems. These include perishing and cracking of rubber components, oxidation of brake discs and calipers, degradation of lubricants and brake fluid through age rather than use, and deterioration of the 12-volt battery. Given that there are no recorded advisory items to confirm wear thresholds, a physical inspection becomes particularly important on this vehicle. For a prospective buyer, careful attention should be paid to age-related deterioration that the MOT test may not fully expose. Tyres should be examined closely for sidewall cracking and perishing, which is common on vehicles of this vintage regardless of tread depth, and the manufacturing date code on the sidewall should be checked to ensure the tyres are not excessively old, as rubber compounds degrade over time even without heavy use. The braking system warrants particular scrutiny, as standing corrosion on the brake discs and seizing or binding of the caliper pistons and slider mechanisms are common on low-use vehicles; during a test drive, listen for any scraping or grinding noises, and feel for any pulling to one side or a soft or inconsistent brake pedal. The underside of the vehicle should be inspected for fluid leaks, corrosion to structural and suspension components, and the condition of the exhaust system, which on a 22-year-old Mercedes can suffer from internal baffle deterioration and external corrosion even at modest mileages. The powertrain, cooling system, and ancillary items also merit close attention given the calendar age of the vehicle. The 12-volt battery should be load-tested, as batteries typically require replacement every four to six years and may be well past their service life; modern electronics on the M-Class can mask a failing battery initially but may produce erratic warning lights or starting issues. Engine oil, transmission fluid (including the automatic gearbox and transfer case, given this is a four-wheel-drive vehicle), coolant, brake fluid, and power steering fluid should all be inspected for condition and replacement history, as these degrade through age irrespective of mileage, and brake fluid in particular should be changed every two to three years due to its hygroscopic nature. On the test drive, listen for any suspension clonks or knocking from the ageing bushes and coil springs, unusual transmission behaviour, and any warning lights or messages on the instrument cluster, and verify that the four-wheel-drive system engages smoothly. Finally, a thorough service history examination is essential to confirm that time-based servicing has been carried out, as a low-mileage vehicle that has been neglected on calendar intervals can present greater mechanical risk than one that has been consistently maintained.
