2008 Mercedes-Benz C 2.1L Diesel · RK58 VRT

The most recent MOT on 2025-09-30 recorded three issues: an inoperative offside rear registration plate lamp, a non-excessive rear differential oil leak, and a severely deteriorated offside front anti-roll bar ball joint dust cover. These findings suggest ongoing maintenance needs, particularly with lighting and suspension components. The vehicle has a history of recurring minor faults, including damaged mirrors, defective indicators, and oil leaks, which have persisted across multiple MOTs. A critical failure occurred in the 2024-10-19 MOT, where an offside front coil spring was fractured or broken. This is a significant safety concern, as a damaged coil spring can compromise suspension integrity and handling. While the subsequent 2024-10-24 MOT passed with similar issues (mirror damage, oil leaks, and low parking brake effort), the presence of a fractured spring in an earlier test indicates a potential risk of further suspension degradation. The pattern of issues shows stability in some areas, such as mirror damage and oil leaks, which have recurred without escalation. However, the 2024-10-19 failure highlights a more serious mechanical defect that was not repeated in later tests, suggesting either repair or mitigation. The vehicle’s mileage of 135,385 miles over 18 years equates to an average of 7,521 miles per year, which is typical for its age. This implies moderate use but does not rule out periods of inactivity, which can accelerate wear on components like seals and rubber parts.
