2014 Mercedes-Benz C 2.1L Diesel · RX64 YOF

The 2.1-litre C-Class diesel is generally economical, with real-world fuel economy typically between 45-55 mpg depending on driving style. Road tax for a 2014 diesel of this engine size usually falls into a mid-range band, though diesel vehicles registered after April 2017 face additional charges in clean air zones such as London's ULEZ — this 2014 car is exempt from the ULEZ charge but may face charges in other zones. Insurance is likely to sit in group 28-38 depending on the exact derivative, which is moderate for an executive saloon. Annual maintenance on a Mercedes of this age tends to be higher than mainstream marques, with items like brake discs, dual-mass flywheels, and AdBlue system servicing representing potentially costly interventions. Estimated annual running cost: £1,400-£1,800.

The most urgent items from the MOT history require targeted inspection. First, the steering lock (advisory on the pass and failure of 2026) is a significant safety and security concern — a Mercedes specialist should diagnose whether this is an ignition switch fault, a steering column issue, or an electronic malfunction, as repair costs vary widely. Second, the broken exhaust joint must be inspected for underlying corrosion, particularly around the flexi section and downstream of the catalytic converter, as these are known weak points on W204/W205 diesel models. Third, the 2025 advisory on anti-roll bar linkage ball joint dust covers ('borderline') and the fluctuating front brake suggest the front suspension and braking system are due for attention. Finally, the headlamp cleaning device inoperativity (failure item) should be checked, as this is a relatively simple fix on most Mercedes models. A general inspection of the timing chain (if applicable to this engine variant), turbocharger, and EGR valve is also advisable on a high-mileage diesel of this age.
