2015 Mercedes-Benz C 2.1L Diesel · G6 OYS

The most recent MOT on 2026-03-02 shows a failure due to critical suspension issues. The nearside front lower suspension arm ball joint’s dust cover failed to prevent dirt ingress, and the spring link CV boot was split. The offside front lower ball joint exhibited excessive wear with play. These defects directly impact handling and safety, as compromised suspension components can lead to loss of control or sudden failure. A recurring pattern of suspension-related issues emerges. The 2024-09-06 MOT noted a severely deteriorated nearside front suspension arm ball joint dust cover, a minor defect at the time. By 2026, this progressed to split boots and worn joints with play, indicating worsening conditions . The 2025-03-10 and 2023-09-11 MOTs were clean, but the 2026 failure suggests neglect or accelerated wear in the intervening period. The vehicle’s mileage of 76,405 miles over 11 years equates to ~6,946 miles annually, which is typical for its age . This implies consistent use rather than long-term storage, reducing concerns about under-use but not eliminating risks from normal wear.
