2014 Mercedes-Benz C 2.1L Diesel · AE14 WTV

Recurring issues with the rear braking system and suspension components define the mechanical history of this Mercedes-Benz C-Class, which most recently achieved a clean pass on 16 April 2025. While the vehicle has demonstrated periods of compliance, the MOT record highlights a persistent trend of brake-related advisories and failures, specifically concerning parking brake efficiency and rear braking balance. These recurring defects, punctuated by a 2024 failure regarding the secondary braking system, suggest that the rear axle assembly has required frequent attention to maintain roadworthiness. Accumulating 88,062 miles over a twelve-year period results in a consistent annual usage rate of approximately 7,338 miles. This steady mileage profile indicates that the vehicle has been in regular operation rather than subjected to prolonged periods of inactivity, which is generally preferable for mechanical health. However, the consistent nature of the mileage means that wear on consumables such as suspension bushes, wheel bearings, and brake discs is expected for a vehicle at this stage of its lifecycle, necessitating a thorough physical inspection of these high-wear areas during a test drive. Given the history of parking brake failures and rear brake imbalance, a prospective buyer must verify the responsiveness of the handbrake on an incline during the test drive. Any sign of the vehicle failing to hold firmly or a pedal that feels spongy or requires excessive travel could indicate that the underlying mechanical issues flagged in 2020 and 2024 have not been permanently rectified. Furthermore, the 2019 advisories regarding slight play in the front wheel bearings and worn brake discs necessitate a check for any audible humming or grinding noises while cornering or braking, as these components are prone to degradation over this mileage. The documented corrosion of the offside rear coil spring, noted as recently as 2024, warrants a visual inspection of the suspension mounting points and the springs themselves for signs of flaking or structural compromise. Listen closely for any metallic knocking or clunking sounds when traversing uneven road surfaces, which could point to worn suspension linkages or further deterioration of the rear spring seats. Additionally, the recurring pattern of uneven tyre wear noted across multiple tests suggests that the vehicle may benefit from a professional four-wheel alignment check to ensure that suspension geometry remains within manufacturer specifications and to prevent premature tyre replacement.
