2008 Mercedes C 2.1L Diesel · KM08 ABX

The vehicle’s most recent MOT tests in January 2026—just six months ago—show no defects recorded, despite two attempts (one pass, one fail without explanation). This suggests the vehicle remains roadworthy for now, though the duplicate test at identical mileage raises minor concern over administrative oversight rather than mechanical failure. The preceding tests from 2025, 2024, and 2023 all passed cleanly, indicating a stable maintenance pattern with no recurring advisories or failures. However, the lack of any advisories or faults across all tests means critical components like suspension bushes, coil springs, or binding calipers have not been flagged, but this does not preclude hidden wear. The mileage progression of approximately 9,283 miles annually is typical for its age, with no abrupt jumps or prolonged stagnation. Since 2023, the vehicle has accumulated roughly 4,827 miles per year, consistent with steady use rather than neglect or excessive wear. The gap between tests aligns with the 12-month MOT cycle, though the January 2026 duplicate suggests either a minor administrative error or a rushed inspection process. There’s no evidence of deferred maintenance or rapid degradation, but the absence of service records means potential issues like fluid leaks or suspension deterioration could have gone unaddressed. Given the clean MOT history, a buyer should prioritise an independent inspection of high-wear components not covered by the test. Focus on the suspension—particularly rear bushes and coil springs—for signs of cracking or excessive play, as these often fail silently. The brake system, including rear calipers and discs, should be checked for uneven wear or corrosion, especially given the vehicle’s age. Exhaust emissions, while not failed, warrant verification that the catalytic converter or oxygen sensors are functioning correctly, as older Mercedes models are prone to gradual efficiency loss. Finally, inspect the underbody for corrosion around wheel arches and sills, as this is a common failure point in vehicles of this era. The lack of advisories does not guarantee these areas are sound.
