2009 Mercedes-Benz C 2.1L Diesel · RF59 WBO

Chronic corrosion of the brake pipes is the most prominent recurring theme in this vehicle's history, appearing consistently from 2020 through 2023. While the records show a pattern of brake line degradation and a 2020 failure for a fractured offside front coil spring, the trajectory has improved in recent years. This is evidenced by the most recent MOT pass on 10 November 2025 and the preceding 2024 test, both of which were completed without any defects or advisories recorded. The recorded mileage of 171,463 miles is consistent with the vehicle's age, averaging approximately 10,086 miles per year. This level of usage indicates that the drivetrain, suspension bushings, and braking system have been subjected to typical long-term wear. Prospective buyers should account for the fact that components reaching the end of their natural service life are more likely to require replacement at this mileage interval. Attention must be paid to the braking system given the history of corroded brake pipes and pitted front discs. During a physical inspection, check the condition of the brake lines for any signs of fresh patching or remaining surface corrosion, particularly at the rear. On a test drive, feel for any inconsistent pedal pressure or judder during braking, which could relate to the previously flagged disc wear. The previous failure of a front coil spring suggests a need to inspect the front suspension for any current signs of sagging or uneven ride height. Listen for knocks or clunks when traversing speed bumps or uneven road surfaces, as this can indicate further wear in the suspension linkages or mounts. Finally, verify the current tread depth and wear patterns of the rear tyres, as these were flagged as worn close to the legal limit in multiple previous tests.
