2018 Mercedes-Benz C 2.1L Diesel · DC18 AEU

The most recent MOT test conducted on 09 June 2026 resulted in a pass with no defects recorded. Evaluating the overall maintenance trend, the vehicle shows a positive trajectory. Although a significant failure occurred in June 2023 due to dangerous rear brake pad wear and major defects regarding worn rear brake discs, the subsequent three years of clean passes suggest that these issues were rectified effectively. This indicates that the vehicle is currently in a stable maintenance cycle, with the previous mechanical shortcomings having been addressed to restore roadworthiness. The recorded mileage of 63,113 miles is highly consistent with the vehicle's eight-year age, representing an average annual run rate of approximately 7,889 miles. This level of usage is considered typical for a private passenger vehicle and avoids the excessive mechanical strain associated with high-mileage commercial or heavy-duty applications. From a technical standpoint, this moderate usage profile suggests that wear on the suspension components, drivetrain, and engine internals should be relatively moderate, provided that the vehicle has been serviced according to the manufacturer's intervals. During a test drive, it is essential to scrutinise the braking system to ensure the previous issues with the rear discs and pads remain resolved. Listen for any metallic grinding, squealing, or high-pitched noises when applying the brakes, and feel for any shudder or pulsation through the brake pedal, which could indicate warped discs or binding calipers. You should also inspect the rear brake discs for surface corrosion or uneven wear patterns and check the thickness of the pads. Furthermore, observe the tyre wear; any significant unevenness on the inner or outer edges could indicate that the suspension bushes or alignment were affected by the previous mechanical issues. As the vehicle is approaching its eighth year, you should also perform several age-related inspections that are not always captured by an MOT. Check the tyre sidewalls for any signs of perishing or cracking, which can occur due to age-related rubber degradation regardless of tread depth. It is also advisable to verify the condition of the 12V battery and check the service book for evidence of time-based fluid replacements, such as brake fluid and coolant, which are critical for maintaining the integrity of the hydraulic and cooling systems. Ensuring these calendar-based maintenance items have been completed will provide further confidence in the vehicle's long-term reliability.
