2014 Mercedes-Benz C 2.1L Diesel · KM64 GSV

The most recent MOT on 2025-10-22 shows a failure due to a nearside front suspension arm ball joint excessively worn (5.3.4 (a) (i)), along with a windscreen washer providing insufficient liquid (3.5 (a)) and offside front tyre damage (5.2.3 (d) (ii)). This failure contrasts with a pass on the same date for the same vehicle, suggesting potential inconsistencies in the testing or reporting process. The recurring tyre damage on the offside front wheel has appeared in multiple MOTs since 2023, indicating a persistent issue that may relate to alignment, suspension wear, or uneven tyre wear patterns. The suspension arm ball joint failure is a new and serious concern, as excessive wear in this component can compromise steering stability and safety. This suggests a worsening trend in suspension integrity, particularly given the vehicle’s low mileage (45,798 miles over 12 years). While low mileage often implies lighter use, it can also lead to undetected wear in components not regularly stressed, such as suspension joints or rubber parts. The tyre damage has remained consistent over time, but its persistence raises questions about whether underlying issues like misalignment or uneven load distribution have been addressed. The vehicle’s mileage of 45,798 miles (3,816 miles per year) is significantly below average for its age, which could indicate periods of inactivity or minimal driving. This may contribute to tyre perishing (as noted in multiple MOTs) and potential stiffness in suspension components due to lack of regular use. However, the low mileage does not necessarily mean the vehicle has been well-maintained, as evidenced by the suspension failure and recurring tyre issues.
