2015 Mercedes-Benz ML 2.1L Diesel · PL15 FUT

The most recent DVSA test on 23 July 2026 recorded a PASS, accompanied by a single advisory noting that the front brake pads are wearing thin. This is the third consecutive year that this same advisory has appeared on the MOT record, having first been flagged in July 2023 and reappearing in 2024 and again in 2026. The trend indicates a stable overall maintenance pattern with no test failures or worsening structural concerns, but the recurrence of the front brake pad advisory suggests progressive wear that has now reached a stage where replacement should be planned imminently. No other advisories relating to brake discs, callipers, hydraulic lines, suspension, corrosion, or exhaust integrity have been recorded across the entire eight-test history, which is a reassuring indicator of general mechanical condition for a vehicle of this age. The recorded mileage of 65,054 miles over an eleven-year period equates to an average annual usage of approximately 5,914 miles, which is notably below the typical mileage for a vehicle of this age and class. The MOT intervals show tests conducted almost exactly annually between July 2019 and July 2026, suggesting the vehicle has been in regular but light use rather than left standing for extended periods. This usage profile is mechanically beneficial in terms of wear on the engine, transmission, and drivetrain, as low-mileage Mercedes-Benz M-Class diesel and petrol units tend to suffer less from internal component fatigue. However, the relatively modest annual mileage means that time-based degradation of consumables and perishable components is likely to be more relevant than mileage-based wear, and this should shape the inspection priorities accordingly. Given the recurring front brake pad advisory, a prospective buyer should arrange a thorough inspection of the braking system prior to purchase. On a test drive, listen for any grinding or scraping noise from the front wheels during light application, which would indicate that the pads have worn beyond their backing plate and are now contacting the discs. Feel for any vibration or shudder through the steering wheel or the vehicle structure under braking, which could suggest worn or scored front brake discs that may require machining or replacement alongside the pads. Inspect the front brake calliper slide pins and guide bushes for seizure, as low-mileage vehicles can develop binding callipers due to corrosion on the sliding surfaces, leading to uneven pad wear and pulling under braking. Check visually for any scoring or lipping on the outer edge of the front brake discs, and confirm that the brake fluid has been renewed in accordance with manufacturer schedules, typically every two years regardless of mileage. Beyond the braking system, a careful physical inspection is warranted given the eleven-year age of the vehicle. Examine all four tyres, including any spacesaver spare, for sidewall perishing and cracking from age-related rubber degradation, which can occur independently of tread depth on low-mileage vehicles; Mercedes-Benz original equipment tyres should also be checked for their production date code on the sidewall. Inspect the underside and wheel arches for any surface corrosion, particularly around suspension mounting points, subframe interfaces, and the exhaust system, as standing moisture and road salt can initiate corrosion even on well-maintained examples. Verify the age and condition of the 12-volt battery, as Mercedes-Benz vehicles of this era are sensitive to voltage stability and a weak battery can produce electrical faults and trigger dashboard warning lights. Finally, confirm that the service book contains evidence of regular annual or time-based servicing irrespective of the modest mileage, ensuring that engine oil, oil filter, air filter, fuel filter, cabin filter, coolant, and automatic transmission fluid have been renewed at the appropriate calendar intervals in line with Mercedes-Benz manufacturer recommendations.
