2013 Mercedes-Benz ML 3.0L Diesel · YD 717

The most recent MOT, carried out on 27 August 2025, resulted in a failure on the basis of dangerous tread depth on both front tyres, with the advisory noting corrosion on the rear shock absorbers. Earlier tests in 2024 and 2022 were passed but each carried advisories – first for front tyre wear approaching the legal limit and later for thin rear brake pads and the same rear‑shock corrosion. The progression from advisory to outright failure indicates a deteriorating trend, particularly in tyre condition, while the shock absorber issue has persisted without resolution. At 52 314 miles recorded for a 2013 model, the vehicle averages roughly 4 000 miles per year, which is considerably below the typical UK usage pattern. Such low annual mileage often points to periods of limited use or prolonged storage, conditions that can accelerate age‑related degradation even when mechanical wear is modest. Components that are more dependent on calendar life – for example rubber bushings, seals, batteries and fluids – may be more vulnerable than the mileage alone would suggest. Prospective buyers should treat the front tyre situation as an immediate safety priority; both tyres must be replaced before any further road use. While inspecting the tyres, verify the DOT code to confirm they are not older than six years, examine sidewalls for cracking, and check for uneven wear that could hint at mis‑alignment or suspension issues. The rear shock absorbers, flagged for corrosion in three consecutive MOTs, should be examined for any oil leakage, loss of damping, or clunking noises when the vehicle is driven over bumps; excessive body roll or a sagging rear ride height would also suggest the need for replacement or refurbishment. The 2022 advisory about thin rear brake pads warrants a fresh measurement of pad thickness and a visual inspection of the discs for scoring, rust or glazing, as worn pads can lead to reduced stopping performance and increased rotor wear. Given the vehicle’s age and low mileage, time‑based maintenance is as critical as mileage‑based wear. The 12‑volt battery should be load‑tested and its terminals inspected for corrosion, as prolonged standing can diminish charge capacity. All engine and transmission fluids – coolant, brake fluid, power‑steering fluid and gearbox oil – should be sampled for water contamination and replaced according to calendar intervals, typically every two to three years. A thorough under‑body inspection for rust, especially around the chassis rails, suspension mounting points and exhaust system, is advisable. During a test drive, listen for any abnormal noises from the steering rack, monitor for pulling to one side, and feel for any shudder or vibration under braking, all of which could reveal hidden wear that the MOT record does not capture. Ensuring a complete service history with documented oil changes and major service stamps will further substantiate the vehicle’s overall roadworthiness.
