2002 Mercedes-Benz ML 2.7L Diesel · WN02 NHX

The last recorded MOT test was a pass on 4 January 2022. However, given the current date of September 2026, the vehicle has been without a valid MOT for over four years, which is a significant red flag regarding its current roadworthiness. The maintenance trend appears to be deteriorating, moving from clean passes in 2016 and 2019 to a series of structural and mechanical advisories in 2020 and 2022. The emergence of corrosion on the sub-frame and brake pipes, combined with a prolonged period of inactivity, suggests a vehicle that has been neglected in recent years. With 146,465 miles recorded over 24 years, the vehicle has averaged approximately 6,103 miles per year. This is a moderate usage rate for its age, suggesting it has not been excessively worked. However, the significant gap in MOT history since 2022 indicates a prolonged period of standing. While the total mileage is acceptable, long-term dormancy often leads to more severe mechanical degradation than consistent high-mileage use, particularly regarding rubber components, seals, and braking systems. Prospective buyers must prioritize a thorough inspection of the chassis and underbody. The 2020 records specifically highlight corrosion on the sub-frame and rear brake pipes, the latter of which were noted as being covered in grease, a common practice to mask or slow the decay of critical lines. This is a significant safety concern. During a test drive, listen for clunks or knocks from the rear suspension, as the corroded rear coil springs are prone to sudden failure. Inspect the brake discs for heavy pitting and scoring, as previously advised, and check for binding calipers or seized sliders resulting from the vehicle standing for several years. The recorded oil leak and the previous misting of the front shock absorber indicate aging seals that likely require replacement. Check for fresh fluid leaks around the engine and transmission. Given the age and the period of inactivity, all calendar-based fluids, including engine oil, coolant, and brake fluid, should be treated as degraded and replaced immediately. Examine all tyre sidewalls for perishing, cracking, or flat spots caused by standing, regardless of the remaining tread depth. Finally, verify the health of the 12V battery and ensure the electrical system is functioning, as the history shows a recurring tendency for lighting failures.
