2014 Mercedes-Benz C 2.1L Diesel · AU04 ALY

A pattern of recurring mechanical wear and component degradation is evident in the MOT history of this Mercedes-Benz C-Class, with the latest test on 16 May 2026 showing a pass despite advisories for suspension wear and a minor defect regarding an anti-roll bar linkage. The record indicates a trend of escalating minor issues and component deterioration, moving from a clean test in 2023 to more frequent advisories concerning braking systems, lighting, and suspension components in the subsequent years. While the vehicle has successfully cleared its most recent inspection, the frequency of failures related to safety-critical items, such as the 2023 dangerous failure for brake pad thickness and the SRS warning lamp fault, suggests a history of intermittent component fatigue. The vehicle has covered 168,351 miles over its approximately 12-year lifespan, representing an average annual accumulation of roughly 14,029 miles. This usage profile is considered high for a vehicle of this age, which typically correlates with increased mechanical stress on consumable parts and structural components. This higher-than-average mileage suggests that the recorded issues with suspension bushes, brake discs, and oil leaks are consistent with the accelerated wear expected from frequent, long-distance driving rather than periods of stationary storage. Prospective buyers should pay close attention to the suspension and steering integrity during a test drive. The advisory from May 2026 regarding a worn front suspension arm pin or bush, combined with the deteriorated offside front lower anti-roll bar linkage dust cover, warrants a physical inspection of the front end. Listen for knocking, clunking, or creaking noises when navigating uneven road surfaces or turning the steering wheel at low speeds, as these symptoms often accompany worn bushes or ball joints. Additionally, the 2024 advisory for an oil leak, though noted as not excessive at the time, should be monitored for any signs of fresh weeping around the engine or transmission casings to ensure the leak has not progressed. The braking system also requires scrutiny given the history of pitted and scored discs in 2025 and a previous dangerous failure for thin brake pads. During a test drive, check for any pedal judder or vibration when applying the brakes at motorway speeds, which can indicate warped or unevenly worn discs. Furthermore, the repeated lighting issues, including headlamp aim and rear position lamp failures, suggest that electrical connections or bulb housings may require attention. A thorough check of all exterior lighting and the smoothness of the braking feel is essential to ensure these previously recorded defects have been adequately addressed.
