2008 Mercedes-Benz ML 3.0L Diesel · KV08 EWB

The vehicle currently shows a worsening maintenance trend following a significant period of neglect. While the vehicle passed its most recent MOT in June 2025 at 180,311 miles, the preceding failure just one month prior revealed a cascade of serious mechanical and structural issues. The transition from a relatively clean certificate in 2022 to a multi-point failure in 2025 indicates that the vehicle has reached a stage where reactive repairs are being performed only when necessary, rather than through preventative maintenance. At 180,311 miles over 18 years, the vehicle has averaged approximately 10,000 miles per year, which is consistent with typical usage for its age. However, there is a notable three-year gap between the May 2022 and April 2025 tests during which the vehicle covered nearly 8,000 miles. The surge of defects in the April 2025 test, including fractured coil springs and corroded brake pipes, suggests that components were run to the point of failure without interval, leading to multiple simultaneous breakdowns in safety-critical systems. A buyer must prioritise a thorough inspection of the rear subframe and braking system. The 2025 record noted corrosion on the rear subframe that was not yet structurally weakened, but on a Mercedes of this age, such rust progresses rapidly. The history also shows recurring issues with the braking circuit, including corroded pipes, a binding rear caliper, and deteriorated hoses. Given that the parking brake was operating at the absolute minimum limit of 16%, the entire handbrake mechanism likely requires a comprehensive adjustment or overhaul to ensure reliable operation. The steering and suspension also require close scrutiny. The offside front power steering hose already showed seepage in the latest test, and the previous fractured coil springs indicate the front suspension geometry is nearing the end of its service life. The presence of rusted and pitted brake discs combined with thin pads suggests that the braking system has not been properly cared for. A potential buyer should check for further signs of fluid leaks from the engine, as an oil leak was previously flagged in 2025.
