2011 Mercedes-Benz C 2.1L Diesel · J3 AVK

The most recent MOT on 2026-01-14 resulted in a failure with multiple critical issues. The offside front coil spring was fractured, and both front suspension arm ball joints showed excessive wear. Front brake discs were worn but not severely, while all four shock absorbers had light oil misting. These defects indicate significant suspension and braking system degradation, which could compromise safety and handling. Recurring mechanical patterns include suspension component wear, particularly ball joints and shock absorbers. Ball joints were flagged in 2025, 2024, and 2026, with increasing severity. Shock absorber oil misting was present in every MOT from 2024 onward, suggesting progressive leakage or internal wear. Brake disc wear and suspension arm issues also reappeared across multiple tests, highlighting ongoing stress on these systems. The trend shows a worsening condition. The 2026 failure included a fractured coil spring—a more severe defect than earlier reports.
