2014 Mercedes-Benz C 2.1L Diesel · FN64 PLV

The latest MOT test for this 2014 Mercedes-Benz C-class was conducted on 2025-12-13 and resulted in a clean pass, indicating no defects were found at that time. However, the vehicle’s MOT history reveals a pattern of recurring advisories and a single major failure in 2023, particularly concerning the front suspension components. The advisories from 2023-12-20 and 2023-01-12—both noting worn suspension arm pins or bushes on both sides—suggest progressive wear in the upper control arms, which is a common issue in vehicles of this age and mileage range, especially when subjected to prolonged periods of standing or light use. The 2023-12-20 failure highlighted an excessively worn near-side front lower suspension arm ball joint, which is critical as it can lead to misalignment, uneven tyre wear, and potential handling instability if left unaddressed. While the 2024 and 2025 MOTs were clean, the history implies that the suspension system has been under stress, warranting careful attention to its condition before purchase. The recorded mileage of 69,306 miles for a vehicle aged approximately 12 years represents a notably low annual usage rate of around 5,776 miles per year, which is unusual for a car of this make and model. Such low mileage often correlates with vehicles that have been stored for extended periods, driven infrequently, or used in environments with reduced demand, such as rural areas or during off-peak seasons. However, low mileage alone does not guarantee optimal mechanical condition, as prolonged standing can accelerate wear in components like suspension bushes, seals, and bearings due to oxidation and corrosion. Additionally, the lack of recent high-mileage accumulation means that consumables like brake pads, tyres, and fluids may not have been subjected to the same level of stress as a vehicle with higher annual mileage, but this also raises concerns about potential hidden issues from past neglect or improper maintenance. The vehicle’s usage profile suggests it may have been exposed to seasonal or operational disuse, which can lead to subtle but critical degradation in components like the suspension, steering linkage, and electrical systems. Given the recurring suspension advisories and the single major failure recorded in the MOT history, the prospective buyer should conduct a thorough physical inspection of the front suspension system. Focus on the upper and lower control arms, particularly the pins, bushes, and ball joints, for signs of excessive play, cracks, or corrosion. On a test drive, listen for unusual noises such as clunks or rattles from the front suspension during cornering, braking, or acceleration, which may indicate worn or failing components. Visually inspect the suspension for uneven tyre wear patterns, which can signal misalignment caused by suspension issues. Additionally, check the alignment settings to ensure they are within manufacturer specifications, as misalignment from worn suspension can lead to further tyre and steering system wear. If the suspension components are confirmed to be in poor condition, the buyer should budget for immediate replacement of the worn ball joints, control arms, and potentially the bushes, as these are critical for roadworthiness and handling. For a vehicle of this age and mileage, particularly one with a history of low or intermittent usage, the buyer should also prioritise checks on other critical systems that may have degraded over time. Inspect the tyres for signs of sidewall cracking or perishing, which can occur even at low mileage due to prolonged exposure to UV light and temperature fluctuations. Verify the tread depth and condition of the tyres, ensuring they meet legal requirements and are suitable for the intended use. Check the 12V battery for signs of corrosion on terminals, poor connections, or reduced charge retention, as low-mileage vehicles can suffer from battery drain from parasitic loads or prolonged disuse. Examine the brake system for signs of corrosion on the discs, particularly on the near-side where the 2023 failure was noted, and check for binding or excessive wear on the calipers or pads. Fluid levels should be topped up to manufacturer specifications, with particular attention to the brake fluid, which can degrade over time even without use, and the coolant, which may have been left stagnant in the system. Lastly, verify that the service book has been updated, especially for time-based maintenance such as the oil change interval, which for this model is typically every 15,000 to 30,000 miles or every 12 months, whichever comes first. If the service history is incomplete, the buyer should arrange a comprehensive service to address any outstanding maintenance requirements.
