2014 Mercedes-Benz C 2.1L Diesel · GY64 UGL

The vehicle’s most recent MOT test on 2026-03-04, just four months ago at 158,007 miles, confirms it remains roadworthy with no defects recorded. This consistency across the last three tests—including two consecutive passes in January 2025—suggests no recurring mechanical failures have been formally documented. However, the repeated failures in February 2024 and January 2025, both at nearly identical mileages (143,802 and 150,472), raise suspicion of unresolved or overlooked issues, particularly if the same components were at fault. The lack of advisories or defects in the most recent passes implies either diligent maintenance between tests or that critical failures were addressed privately without official record. Buyers should treat this as a cautionary signal rather than a guarantee of reliability. The recorded mileage of 158,007 miles over 12 years equates to an average of 13,167 miles annually, which is unusually high for a vehicle of this age. This rapid accumulation suggests either intensive use or prolonged periods of neglect, both of which accelerate wear on suspension bushes, coil springs, and drivetrain components. Notably, the mileage jumps between tests—from 143,802 to 150,472 in under a year—indicate the vehicle was likely in active service rather than stored. The absence of any MOT tests between February 2024 and January 2025 (a gap of 11 months) is also unusual, as vehicles typically undergo testing annually. This could imply either a temporary exemption or that the owner deferred testing, potentially masking underlying issues. Given the pattern of repeated failures at similar mileages, a buyer should prioritise an independent inspection of the braking system, suspension geometry, and exhaust emissions. The February 2024 failure, though undocumented, may have involved binding calipers, worn brake discs, or failing suspension bushes—common issues in high-mileage Mercedes-Benz models. Corrosion at wheel arches, subframe mounts, or exhaust supports should also be scrutinised, as these are often overlooked but critical to structural integrity. The lack of advisories in recent passes does not preclude hidden wear; tyre condition, fluid levels (brakes, power steering, coolant), and electrical components (lights, sensors) warrant immediate verification. The vehicle’s age and mileage demand thoroughness—no assumptions should be made based solely on MOT history.
