2015 Mercedes-Benz C 1.6L Diesel · WP15 FXJ

This Mercedes-Benz C, tested most recently on 5 February 2026 at 141,063 miles, has maintained a clean MOT history over the past five annual tests with no defects or advisories recorded. The consistent pass status suggests that, at least in terms of statutory MOT requirements, the vehicle has been kept within legal limits for emissions, brakes, lights, and structural integrity during each inspection cycle. However, the absence of advisories or minor faults does not preclude underlying issues—particularly given the vehicle’s age and mileage—so a thorough mechanical inspection remains essential. The most recent test’s clean slate is reassuring, but the lack of any recorded concerns over five years could also imply that previous owners either prioritised basic compliance or that the vehicle has been driven in a manner that delayed more obvious wear. The recorded mileage progression—rising from 102,457 miles in February 2023 to 141,063 miles in February 2026—indicates an average of approximately 12,800 miles per year, which is elevated for a vehicle of this age. The intervals between tests are consistent at roughly one year, with no extended periods of inactivity or unusually rapid mileage accumulation. While this suggests the vehicle has been in regular use rather than stored, the high annual mileage implies accelerated wear on suspension components (bushes, coil springs, and dampers), brake systems (pads, discs, and calipers), and drivetrain elements (transmission fluid, differentials). The absence of gaps in service history means there’s no evidence of prolonged neglect, but it also means there’s no documented maintenance beyond the MOT’s basic requirements. Given the vehicle’s age and mileage, a prospective buyer should prioritise an inspection of the suspension system, particularly the rear axle bushes and coil springs, which are prone to fatigue at this mileage. The brake system warrants close scrutiny, as repeated high mileage could have contributed to uneven wear on pads and discs, or potential binding in calipers—even if not yet severe enough to fail an MOT. Structural corrosion, particularly around wheel arches, sills, and the subframe, should be checked, as this is a common failure point for Mercedes-Benz models of this era. Additionally, the exhaust system and catalytic converter should be inspected for leaks or excessive rust, as these are often overlooked until they reach a critical stage. While the MOT record shows no red flags, these areas are where deferred maintenance could lead to costly repairs.
