2014 Mercedes-Benz CLA 2.1L Diesel · AM14 ROG

The vehicle most recently passed its MOT in June 2026, following a failure related to the front windscreen washer system. Evaluating the overall maintenance trend, the history suggests a reactive approach to vehicle upkeep. The car has frequently failed on non-mechanical, regulatory items, including registration plate compliance, headlamp aim, and the functionality of the engine malfunction indicator lamp. While the absence of major structural or braking failures in recent years is a positive sign for its mechanical foundation, the pattern of addressing defects only when prompted by the MOT test suggests that preventative maintenance may not be consistently prioritised. With 121,968 miles recorded over approximately twelve years, the vehicle has averaged roughly 10,164 miles per annum. This usage is entirely typical for its age and does not indicate extreme heavy-duty use or excessive idling. However, at this mileage, the vehicle is entering a stage where wear on major consumables is expected. You should be prepared for the potential degradation of suspension bushes, coil springs, and various drivetrain components, as well as the natural wear associated with a high-mileage premium vehicle. A current advisory notes a nail in the offside rear tyre, which requires immediate attention. You must confirm whether this has been professionally repaired or if the tyre needs replacement, as a nail can cause slow punctures or sudden failure. Given the previous failure regarding the engine malfunction indicator lamp, it is critical to perform a full dashboard diagnostic during your test drive to ensure all warning lights function as intended. Additionally, verify that the windscreen washer system is fully operational and that the jets provide an even spray, as this was a recent cause of failure. Due to the vehicle's age, you should also conduct a thorough physical inspection for age-related degradation. Check the tyre sidewalls for any signs of perishing or cracking and inspect the underbody for corrosion on the exhaust and suspension components. During the test drive, listen for any suspension clunks or knocks that might indicate worn bushes or dampers, and check for any brake shudder or binding calipers. Finally, ensure the service history reflects regular oil changes and time-sensitive fluid replacements, such as brake fluid and coolant, to ensure the long-term health of the engine and braking systems.
