2018 Mercedes-Benz C 2.1L Diesel · KT18 BOU

A pattern of emerging wear on critical chassis and braking components defines the recent history of this vehicle, following several years of clean records. While the most recent test on 9 January 2026 resulted in a pass, it introduced new advisories for slight play in both front lower suspension arm ball joints. This follows a December 2024 failure categorized as dangerous due to insufficient tyre tread depth and a January 2024 test that flagged worn and pitted brake discs alongside thin rear brake pads. The vehicle has covered 96,335 miles over approximately eight years, averaging roughly 12,042 miles per year. This higher than average annual accumulation suggests a usage profile characterized by consistent, high-mileage travel. Mechanically, this level of usage typically accelerates the wear of consumables and structural components, which is reflected in the recent transition from clean MOT certificates to those flagging suspension and braking system degradation. Attention should be directed toward the front suspension geometry and the condition of the lower arm ball joints. During a test drive, listen for knocking or clunking sounds when traversing uneven road surfaces or when turning the steering wheel at low speeds, as these are typical symptoms of the play recorded in the January 2026 test. The current state of the suspension linkages will determine whether immediate replacement is required to maintain steering precision and prevent premature tyre wear. The braking system requires close scrutiny given the 2024 records of pitted and worn discs along with thin pads. A test drive should include several controlled stops to check for pedal judder or abnormal grinding noises, which would indicate that the previously flagged disc corrosion or wear has persisted. Additionally, verify that all tyres have been replaced since the dangerous failure in December 2024 and inspect the tread depth across all four corners to ensure they meet legal requirements.
