2015 Mercedes-Benz C 2.1L Diesel · LE12 BET

The vehicle’s most recent MOT test on 2025-07-03 confirms it passed without defects, though it was preceded by a failure on 2025-07-02 at the same mileage—an unusual but documented anomaly. The pattern over the past three years shows consistent failures and passes at identical mileages, suggesting either a test centre error or a brief, unresolved issue at each renewal. No recurring faults were logged, which implies the vehicle has not suffered from persistent mechanical failures. However, the repeated failures at identical mileages warrant scrutiny of whether the same underlying condition was overlooked or if the vehicle was simply retested after minor adjustments. The recorded mileage progression reveals a steady accumulation of approximately 11,000 miles annually, which aligns with typical usage for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, indicating consistent driving rather than prolonged neglect or storage. The most recent test occurred just over a year ago, placing it within the DVSA’s recommended 12-month interval for this vehicle category. While this is technically within the legal window, the repeated failures at the exact same mileage—rather than a gradual increase—suggest the previous owner may not have prioritised addressing minor issues before renewal. Given the lack of specific defect details in the MOT history, a buyer should prioritise an independent inspection of the suspension components, particularly the rear axle and bushes, as these are common failure points in Mercedes-Benz models of this era. The repeated failures at identical mileages could imply a recurring issue with brake binding, suspension wear, or even minor structural corrosion that was not formally recorded. Additionally, the absence of advisories means no pre-existing conditions were flagged, but the tyre tread depth should be verified—failing twice on this criterion in past records suggests basic maintenance may have been inconsistent. Finally, the exhaust system and emissions should be checked for leaks or excessive corrosion, as these are often overlooked but critical for long-term reliability.
