2009 Mercedes-Benz C 2.1L Diesel · D7 YLA

The vehicle’s most recent MOT test on 2025-07-18 confirms it passed without defects, though the record reveals an unusual pattern of two consecutive tests in July 2024—one failure and one pass—before returning to a clean slate. This suggests either a temporary oversight in maintenance or a minor, correctable issue that was resolved before the second 2024 test. The absence of any advisories or recurring faults in the last two successful tests indicates no obvious mechanical degradation or neglect, but the 2024 anomaly warrants closer scrutiny of components that might have been at risk of failure. The recorded mileage of 108,445 miles over 17 years equates to roughly 6,379 miles annually, a rate consistent with typical light-to-moderate usage for a vehicle of this age. There are no evident gaps in service intervals to suggest prolonged neglect, nor is there rapid mileage accumulation that would imply aggressive driving. The most notable irregularity is the double testing in 2024, which could imply a brief period of uncertainty in maintenance or a last-minute correction before the pass. Without service records, it remains unclear whether the failure in July 2024 was due to a single component failure or a broader issue that was swiftly addressed. Given the lack of specific faults in the MOT history, a buyer should prioritise an independent inspection of high-wear items such as suspension bushes and coil springs, particularly rear, where binding brakes were flagged in the 2024 failure. The absence of corrosion advisories does not rule out structural rust, especially in the wheel arches or subframe, which can develop silently over time. Exhaust emissions systems should also be checked, as repeated failures in this category often indicate catalytic converter or sensor issues. Finally, the brakes—particularly the rear—demand thorough examination for uneven wear, glazing, or binding calipers, as these are common causes of MOT failures in older Mercedes models.
