2008 Mercedes-Benz C 2.1L Diesel · FT57 YDA

The most recent MOT test on 2025-12-17 resulted in a failure, though no specific defects were recorded—an unusual omission that raises immediate concern. The preceding test cycle in December 2024 was also marked by failure, despite the vehicle passing on the same day before failing immediately after. This inconsistency suggests either a testing anomaly or a critical issue that evaded detection, but the lack of documented faults means no clear pattern of recurring problems is visible. Without visible defects or advisories, the roadworthiness status remains ambiguous, though the repeated failures warrant scrutiny of components that often slip through standard MOT checks, such as suspension geometry, drivetrain seals, or electrical systems that may trigger intermittent faults. The mileage progression shows a steady accumulation of approximately 8,000 miles annually, consistent with typical usage for a vehicle of this age. There are no extended gaps or abrupt spikes in mileage, indicating the car has been driven rather than stored. However, the recorded mileage of 183,209 miles at the latest test suggests significant wear on high-friction and high-stress components, particularly brakes, suspension bushes, and drivetrain elements. The absence of advisories in any test further implies either diligent maintenance or a history of deferred servicing, though the latter cannot be ruled out without service records. Given the lack of documented faults in the MOT history, a buyer should prioritise an independent inspection of the suspension system—coil springs, bushes, and dampers—where wear often goes unnoticed until advanced. The brakes, despite no failures, should be examined for uneven wear or binding calipers, as older Mercedes-Benz models are prone to brake rotor distortion or master cylinder leaks. Structural integrity, particularly around wheel arches and sills, should also be assessed for corrosion, which can compromise the chassis. Electrical systems, including the immobiliser and battery condition, warrant attention, as intermittent failures are common in this age range. The absence of advisories does not guarantee these areas are sound, but they represent the most likely candidates for hidden deterioration.
