2013 Mercedes-Benz C 2.1L Diesel · SM03 ADM

The vehicle shows a history of reactive maintenance where faults are often addressed only after failing an MOT test. The most recent test conducted in December 2025 at 134,394 miles passed after a failure due to headlamp aim being too high, which is a minor adjustment. However, the failure in December 2023 at 119,875 miles revealed significant mechanical neglect, including an inoperative engine management light, a failed parking brake test, and an excessively worn suspension arm ball joint. While these issues appear theoretically rectified, the frequency of multi-component failures suggests the owner relies on the minimum legal requirements rather than proactive preventative servicing. At 134,394 miles over 13 years, the car averages approximately 10,300 miles per year, which is consistent with typical usage for its age. The record from 2021 at 101,240 miles is particularly concerning regarding drivetrain and steering integrity, flagging play in the steering rack joints, wheel bearing play, and power steering seepage. These issues indicate significant wear on the front-end assembly that often requires expensive repairs. The recurring mention of tyre tread depth reaching the legal limit in 2021, 2022, and 2024 confirms a consistent pattern of delaying consumable replacements until they become unsafe. A prospective buyer should closely inspect the front suspension and steering components, as the record has historically flagged rack play, ball joint wear, and bearing issues. The parking brake failure in 2023 also warrants a physical check to ensure the mechanism is fully adjusted and not seized. While the 2025 test showed no new defects, the previous trend of structural-related wear and neglected consumables suggests that the vehicle is nearing a phase where high-mileage components will require frequent replacement.
