2009 Mercedes-Benz ML 5.0L Petrol · KR09 OKW

A recurring theme in the MOT record is the condition of the rear brake cables, both nearside and off‑side, which were flagged as damaged but not to excess in the most recent test on 7 July 2026. Earlier tests also highlighted an off‑side front brake pipe with corrosion and grease build‑up, and a series of tyre‑wear advisories across several years. Apart from a single lamp failure in 2020, the vehicle has consistently passed its annual MOTs, suggesting that while no catastrophic failures have been recorded, there is a pattern of wear and minor deterioration in the braking and tyre areas that warrants close inspection. With 58 815 mi recorded on a 2009 model, the average annual mileage works out to roughly 3 460 mi, well below the typical UK usage rate for a vehicle of this age. The low mileage reduces cumulative wear on engine and transmission components, yet it may also indicate periods of limited use where corrosion can develop, especially on exposed brake hardware and suspension linkages. The uninterrupted yearly MOT schedule shows the car has been regularly tested, providing a reliable mileage trace without significant gaps. When evaluating the rear brake system, feel for any slack or excessive play in the handbrake lever and listen for squealing or grinding when applying the brakes, particularly under load. Inspect the rear brake cables for fraying, corrosion at the attachment points, and ensure the cables move freely without binding. The off‑side front brake pipe should be examined for rust, pitting, or grease residues that could compromise sealing; a firm, consistent pedal feel without sponginess is essential. Any signs of fluid leakage around the pipe or at the brake calipers would merit immediate repair. Tyre condition demands particular attention: the front tyres have previously been noted as close to the legal tread limit on the inner edges, and the off‑side rear tyre showed cracking or perishing. Verify tread depth across the width of each tyre, inspect sidewalls for cracks, bulges, or foreign objects, and confirm that tyre age (DOT code) is within a reasonable service window. The oil‑leak advisory from 2025 suggests a minor seepage that should be traced – check the engine bay for fresh oil spots, especially around the valve cover and oil filter housing, and confirm the oil level is correct and the oil appears clean. Finally, confirm that all external lamps, including the position lamp that failed in 2020, operate correctly, as this is a legal requirement and an indicator of the vehicle’s electrical health.
