2011 Mercedes-Benz C 2.1L Diesel · KN11 CVY

The most recent MOT test on 29 August 2024 resulted in a pass, though the vehicle has a pattern of failing on minor electrical or auxiliary items before passing shortly after. The maintenance trend is concerning as several advisories have persisted across multiple years, specifically the front brake discs, which have been noted since September 2023. This suggests a reactive approach to maintenance rather than a proactive one, where defects are monitored but not rectified until they potentially become major failures. With 98,904 miles recorded over approximately fifteen years, the vehicle has averaged roughly 6,594 miles per year. This is a typical usage profile for a premium saloon of this era, suggesting it has not suffered from the extreme wear associated with high-mileage commuting nor the degradation common in vehicles that stand for extended periods. Mechanically, this mileage suggests the drivetrain and chassis should still be robust, provided the service intervals have been strictly adhered to, although consumables and rubber components will be reaching the end of their natural lifespan. Prospective buyers must pay close attention to the braking system and steering gear. The recurring advisory for worn, pitted, or scored front brake discs indicates significant surface degradation and potential corrosion, which can lead to brake shudder or reduced stopping efficiency. During a test drive, feel for any pulsations through the brake pedal. Furthermore, the reported wear in the steering column universal joint is a critical point of inspection; listen for clicking or notchiness when turning the steering wheel from lock to lock, as this component is essential for precise steering input and safety. The history also notes a non-excessive oil leak and previous rear tyre wear issues. You should inspect the engine bay and the underside of the vehicle for fresh oil residue, particularly around the gaskets and oil filter housing, as these leaks can worsen over time. Check the current condition of all tyres for uneven wear patterns, which could indicate misalignment or worn suspension bushes. Finally, verify the service history to ensure that the oil leak has been investigated and that the vehicle has received regular fluid changes to prevent internal engine sludge and maintain the integrity of the seals.
