2012 Mercedes-Benz C200 Executive SE CDI Bluecy A 2.1L Diesel · BL12 NGZ

The 2012 Mercedes-Benz C200 CDI last passed its MOT on 1 April 2025 with no defects recorded, placing it in a stable roadworthiness state for the time being. The absence of advisories or failures across the past three tests—including the most recent—suggests the vehicle has not experienced any recurring mechanical issues that would warrant immediate concern. However, the MOT cycle is now overdue by nearly four months, which is critical given the vehicle’s age and mileage. A recent inspection is essential to verify that no latent failures—such as degraded suspension bushes, binding calipers, or corrosion-related structural weaknesses—have developed since the last test. The recorded mileage progression shows a consistent average of approximately 10,600 miles per year, which is typical for a vehicle of this age. The gaps between tests align with the standard 12-month MOT interval, with no unusual spikes or prolonged periods of inactivity. The most recent test at 148,902 miles in April 2025 indicates the vehicle has covered roughly 15,763 miles since then, a rate that, while moderate, suggests ongoing use rather than neglect. There is no evidence of extended periods off the road, which could have allowed for corrosion or fluid degradation. Given the clean MOT history, the primary focus for an in-person inspection should centre on high-wear components that are not routinely checked in a standard MOT. The suspension—particularly the rear coil springs and bushes—should be examined for excessive play or cracking, as these are common failure points in diesel Mercedes models of this era. Brake discs and calipers, especially the rear, warrant close scrutiny for uneven wear or binding, as the MOT does not test for lateral wear or caliper seizure. Structural integrity, including underbody corrosion around the sills and wheel arches, must also be assessed, as diesel vehicles are prone to rust-related failures over 14 years. Finally, the exhaust system should be inspected for leaks or excessive corrosion, particularly at the catalytic converter and muffler joints, which are often overlooked until they fail.
