2017 Mercedes-Benz C 2.1L Diesel · SE12 RAP

The vehicle’s most recent MOT test on 2025-06-09 confirms it remains roadworthy, though the immediate preceding test on 2025-06-06—just three days earlier—resulted in a failure without recorded defects. This anomaly suggests either a minor oversight in test procedures or a temporary operational issue not captured in the official record. Beyond this, the consistent pass status across all prior tests indicates no recurring mechanical failures. However, the lack of advisories or defects in any of the five MOTs means there is no documented evidence of pre-existing issues requiring attention. The vehicle’s compliance with emissions and structural checks appears stable, though the absence of advisories does not preclude hidden wear or deferred maintenance. The recorded mileage progression of roughly 10,424 miles annually is typical for a vehicle of this age, with no abrupt spikes or prolonged periods of inactivity. The gap between the 2024 and 2023 tests—just over 11 months—aligns with standard MOT intervals, and the mileage increase of 4,689 miles in that period reflects steady usage. There is no evidence of excessive wear from high mileage accumulation, nor does the record suggest prolonged neglect, as the vehicle has been tested annually without fail. That said, the near-identical mileage between the 2025 failure and pass (93,819 vs. 93,820) is unusual and warrants scrutiny of whether the vehicle was driven between tests or if the failure was procedural. Given the absence of recorded defects or advisories, the primary focus for an in-person inspection should centre on suspension components—particularly rear suspension bushes and coil springs—given their susceptibility to wear at this mileage. The brakes, while not flagged in MOTs, should be checked for uneven pad thickness, binding calipers, or excessive corrosion on discs, as these are common failure points in Mercedes-Benz models. Structural integrity, including underbody corrosion around the sills and wheel arches, should also be examined, as rust can compromise chassis rigidity over time. The lack of advisories does not guarantee these areas are intact, so visual and functional checks are essential. Finally, the engine bay should be inspected for fluid leaks, particularly around the oil and coolant systems, to confirm no silent degradation has occurred between tests.
