2010 Mercedes-Benz ML 3.0L Diesel · PC10 DAC

The most recent MOT on 20 November 2025 was a pass, albeit with a number of minor defects and advisories relating to the front drive‑shaft CV boot, front suspension arm pins and bushes. This follows a failed test the previous day that highlighted a serious engine management light, a non‑functioning off‑side stop lamp, a broken rear brake lining, a deep cut on the near‑side front tyre and the same deteriorated CV boot. Earlier failures in 2022 included a fractured rear coil spring and tyre damage, while the intervening years (2021‑2024) were clean. The pattern shows that significant faults have been addressed and the vehicle now meets the legal standards, but the recurrence of suspension bush wear, tyre damage and brake‑system concerns suggests a maintenance approach that has been largely reactive rather than preventative. At 110 653 miles the ML averages roughly 6 900 miles per annum over its sixteen‑year life, which is typical for a vehicle of this age. There are no obvious mileage gaps in the recorded history, indicating a fairly steady usage rather than prolonged periods of storage. The moderate annual mileage means that wear on consumables such as tyres, brakes and suspension components will be in line with normal depreciation, but the vehicle’s age means that many parts are also subject to calendar‑related deterioration regardless of distance travelled. A prospective buyer should give particular attention to the front drive‑shaft CV boot that was noted as severely deteriorated with grease seepage; any fresh grease on the wheel arch or a whine from the front axle under acceleration would indicate a leak that could lead to joint failure. The front suspension arm pins and bushes were flagged as worn, so a thorough inspection for play when the wheel is rocked fore and aft, and listening for clunking over bumps, is essential. The rear coil spring that fractured in 2022 should be verified as having been replaced; any sagging of the rear ride height or uneven tyre wear could reveal lingering issues. The broken rear brake lining and the dangerous near‑side front tyre cut recorded in 2025 must be confirmed as rectified – check that the brake pads and discs are free from scoring, that the pads are correctly seated and that there is no vibration or shudder when braking. The engine MIL fault noted in the failed test suggests a possible sensor or emission‑control problem; a diagnostic scan should be performed to ensure the fault has been cleared and that the engine runs smoothly without misfires or rough idle. Finally, verify that the off‑side stop lamp now operates correctly and that all exterior lighting is functional. Given the vehicle’s sixteen‑year age, even with a clean recent MOT it is prudent to inspect items that deteriorate with time. Examine the tyre sidewalls for cracking, perishing or dry rot, especially on the front tyres that have a history of cuts and damage; replace any tyre that shows age‑related hardening. Inspect the under‑carriage for rust, particularly around the wheel arches, suspension mounting points and exhaust system, as prolonged exposure can compromise structural integrity. Test the 12 V battery’s cranking voltage and check for signs of sulfation, since batteries over a decade old often lose capacity. Drain and replace all service fluids – engine oil, coolant, brake fluid and power‑steering fluid – as they degrade with age even if mileage is modest. Finally, review the service book for evidence of regular oil changes, timing chain or belt service (if applicable), and any recorded replacement of wear items such as spark plugs, fuel filter and air filter, to gauge how diligently the previous owner has maintained the car.
