2010 Mercedes-Benz C 1.8L Petrol · DU10 FFK

The vehicle’s most recent MOT tests, conducted just six months ago on 2025-11-20, reveal a concerning pattern of repeated failures despite identical mileage readings of 71,253 miles. Both tests in November 2025 resulted in a pass followed immediately by a fail—an anomaly in the DVSA system that suggests either a technical error in the testing process or, more likely, a deliberate attempt to bypass genuine inspection. The lack of recorded defects in either test makes it impossible to determine the precise cause, but the inconsistency undermines confidence in the vehicle’s current roadworthiness. Previous tests in November 2024 and October 2023 also passed without failings, indicating a stable pattern of compliance until the most recent cycle. The absence of advisories or recurring issues in earlier records suggests that, if the failures were genuine, they may have been isolated to non-structural components—though the lack of transparency is itself a red flag. The vehicle’s mileage progression of roughly 4,453 miles per year over its 16-year lifespan is unusually low for a Mercedes-Benz C-Class, particularly given its age. Between October 2023 and November 2024, the odometer advanced by 6,928 miles—a modest increase that aligns with the broader trend. However, the identical mileage readings of 71,253 miles for both November 2025 tests raise suspicion of tampering or an error in recording. Such stagnation could imply prolonged periods of inactivity, which may accelerate degradation in suspension bushes, coil springs, and brake calipers due to lack of motion. Alternatively, it might reflect deliberate odometer manipulation to conceal higher mileage, a practice that often correlates with neglected maintenance. The gap between tests—just one year between 2024 and 2025—suggests the vehicle was kept in regular use until the final cycle, but the abrupt failure sequence warrants scrutiny of whether critical components were overlooked. Given the lack of specific defect details in the most recent tests, a buyer should prioritise an independent inspection of high-wear areas that often fail without obvious warning signs. Focus on the suspension system, particularly the rear bushes and coil springs, as these components degrade gradually and may exhibit binding or uneven wear without visible corrosion. The repeated failures also necessitate checking for binding brake calipers or seized wheel bearings, which could cause sudden failure during testing. Structural integrity should be assessed for corrosion, particularly around the wheel arches, sills, and subframe, as prolonged inactivity can accelerate rust formation. Exhaust emissions should be monitored for leaks or catalytic converter inefficiency, as these are common fail points in older Mercedes-Benz models. The absence of advisories in earlier tests does not guarantee current reliability, so a thorough brake fluid flush, power steering fluid check, and differential oil inspection are advisable to rule out silent degradation.
