2009 Mercedes C 6.2L Petrol · V8 XOC

The most recent MOT, conducted on 27 November 2025 at 85,888 miles, resulted in a pass, yet the maintenance trend remains a concern due to a recurring structural defect. The tester flagged both the Nearside and Offside Front brake pipes as corroded and covered in grease or other material. This specific advisory, relating to section 1.1.11 (c), is not a new development. It appeared in the November 2023 test and the October 2022 test, indicating a persistent issue with corrosion on the braking system that has been monitored rather than rectified over a three-year period. While the vehicle has not failed a test on this specific point, the repeated identification of corroded brake pipes suggests a slow degradation of hydraulic integrity that a buyer must take seriously. The vehicle presents a remarkably low mileage profile for a 2009 model. At 85,888 miles, the annual accumulation averages roughly 5,052 miles. The MOT records confirm this steady but light usage, showing a jump of 2,733 miles between the November 2024 pass and the November 2025 pass. Prior to that, the mileage increased by 2,225 miles between November 2023 and November 2024, and only 1,096 miles between October 2022 and November 2023. Such low mileage generally reduces wear on mechanical components, but the prolonged intervals between tests and the static mileage at the most recent test suggest the vehicle may have been stationary for extended periods. Long-term sitting often accelerates the deterioration of rubber seals, brake fluid moisture absorption, and localized corrosion on steel brake lines. A buyer must prioritize a thorough inspection of the braking system and structural underbody. The repeated advisories regarding corroded front brake pipes demand a physical check for pitting and wall thickness integrity, particularly where the lines are contaminated with grease, which can trap moisture against the metal. The tester also flagged tyre wear patterns in November 2024, noting inner edge wear and exposed cords on the front axle. This points to potential tracking issues or worn suspension bushes and track rod ends. Even though the tyres were replaced before the 2025 test, the underlying geometric fault causing uneven wear may still exist. Inspect the front suspension components and subframe mounting points for corrosion, as low-mileage vehicles that sit idle frequently suffer from surface rust that compromises structural integrity over time.
