2008 Mercedes ML 3.0L Diesel · SL08 UJF

The 2008 Mercedes ML presents a stable roadworthiness profile, with its most recent MOT on 3 October 2025 at 135,089 miles recording zero defects. That clean pass followed an earlier failure on the same day for minor lighting faults, an inoperative nearside repeater and a registration plate lamp issue, both of which were evidently rectified before the retest. The absence of any advisories or failures in the current certificate is a positive indicator, though the record only extends back to 2022, limiting the depth of trend analysis. The mileage pattern is consistent with gentle, regular use. The vehicle covered 11,765 miles between the March 2022 test at 123,324 miles and the March 2023 test at 132,125 miles, then just 2,964 miles over the following two years leading to October 2025. That slowdown suggests either reduced daily use or extended periods of standing, which can introduce its own concerns around brake corrosion, perished rubber components, and fuel system condensation. The annualised average of roughly 7,500 miles sits squarely within typical figures for an eighteen-year-old vehicle of this class. The recurring tester notes regarding engine covers and undertrays fitted at every recorded test from 2022 onwards indicate the vehicle has been consistently presented with these panels in place, which can mask visual inspection of the engine bay, subframe, and front suspension mounting points. A prospective buyer should request removal of these covers to examine the structural integrity of the front crossmember, inner wing arches, and lower suspension arms for corrosion, particularly around the rear subframe mounting points known to corrode on this generation ML. The October 2025 failure for lighting faults, while minor, warrants a full check of the rear lamp cluster wiring and the nearside repeater socket for water ingress or corroded terminals, as these are common failure points on the W164 platform. Beyond the MOT data, a physical inspection should focus on the condition of the front lower suspension bushes, anti-roll bar links, and coil springs for sag or fracture, along with the rear brake calipers, which are prone to sticking on vehicles that have spent time stationary. The air suspension compressor and air springs, if fitted, deserve close scrutiny for leaks or failure, as does the exhaust system for corrosion at the rear silencer and lambda sensor threads. Given the low recent mileage, a thorough test drive covering varied speeds and braking conditions will reveal whether the drivetrain, steering rack, and transmission mountings have deteriorated through age rather than use.
