2012 Mercedes-Benz C 2.1L Diesel · KV62 AEL

The latest MOT test for this Mercedes-Benz C-Class was passed on 19 May 2026, but the result must be viewed with caution due to the severity of the failure immediately preceding it. The vehicle previously failed on dangerous defects involving multiple tyres with tread depths below the legal 1.6mm limit and a fractured front coil spring. The maintenance trend appears reactive rather than preventative, as significant safety-critical components are being addressed only at the point of MOT failure. While the vehicle is currently compliant, the presence of worn front control arm bushes as a new advisory suggests that the suspension system is undergoing progressive degradation. The recorded mileage of 148,763 miles over approximately 14 years equates to an annual average of roughly 10,626 miles. This represents typical usage for a vehicle of this age and suggests it has been used regularly for commuting or general transit rather than being subjected to extreme high-speed motorway use or long periods of stationary neglect. Mechanically, this level of mileage means that while the engine may be robust, various ancillary components, rubber bushings, and suspension elements are likely approaching the end of their reliable service life and will require more frequent inspection. Prospective buyers should pay close attention to the front suspension during a test drive. The history of major failures for worn ball joints and the current advisory for worn control arm bushes indicate that the steering and handling characteristics may be compromised. Listen for any rhythmic knocking, clunking, or creaking sounds when driving over speed bumps or uneven road surfaces, and be alert to any pulling to one side or a vague, imprecise sensation through the steering wheel. Furthermore, the 2025 advisory regarding a non-excessive coolant leak warrants a careful inspection of the engine bay for any signs of weeping from the radiator, hoses, or water pump, as these leaks can lead to serious overheating if left unmanaged. Finally, the repeated issues with tyre tread depth and edge wear suggest that wheel alignment or suspension geometry may be out of specification. Inspect the current tyres for any uneven wear, particularly on the inner or outer edges, which would indicate that the suspension bushes or alignment are causing incorrect tyre contact. Given the vehicle's age, also check the tyres for sidewall perishing or cracking, which can occur even if tread depth is sufficient. It is also advisable to verify the service history to ensure that essential fluids, such as brake fluid and coolant, have been replaced according to the manufacturer's time-based intervals to prevent internal corrosion and component failure.
