2015 Mercedes-Benz C 2.1L Diesel · EA65 TCK

A pattern of recurring issues with suspension components and braking efficiency defines the mechanical profile of this Mercedes-Benz C-Class. The vehicle's most recent history shows a significant decline in immediate roadworthiness, evidenced by a dangerous failure on 25 March 2026 due to rear tyre tread depth falling below the legal 1.6mm limit, followed by a pass on 31 March 2026 that carried advisories for both front tyres being worn close to the legal limit and worn on the edges. This follows a more complex failure in March 2024, where the vehicle failed on major grounds regarding both service brake and parking brake efficiency, alongside worn suspension arm ball joints. While the 2025 test showed no defects, the subsequent 2026 failures suggest a trend of components reaching the end of their service life simultaneously. The vehicle has covered 136,298 miles over its eleven-year lifespan, averaging approximately 12,391 miles per year. This represents a higher-than-average annual mileage for a vehicle of this age, which typically correlates with increased wear on high-frequency consumable items and structural linkages. This consistent usage pattern suggests the vehicle has been regularly driven rather than sitting stationary, which can prevent certain types of degradation but accelerates the wear on suspension bushes, ball joints, and braking systems. The cumulative mileage necessitates a closer inspection of the drivetrain and chassis components that are subject to constant load and movement. Prospective buyers should pay particular attention to the front suspension geometry and steering response. Given the history of worn ball joints and deteriorating dust covers on the nearside front lower suspension component, a test drive should involve checking for any knocking, clunking, or popping sounds when navigating uneven surfaces or turning the steering wheel at low speeds. Any sensation of wandering or pulling to one side could indicate that the previously flagged suspension issues have not been fully rectified or that other bushings have since perished. The braking system and tyre condition also require rigorous scrutiny. The history of major failures regarding service and parking brake efficiency means the pedal feel must be evaluated for any sponginess, pulsation, or unevenness under heavy braking. The parking brake should be tested for its ability to hold the vehicle firmly on an incline. Furthermore, the recent advisories regarding edge wear on the front tyres suggest potential issues with wheel alignment or camber settings. During the test drive, listen for rhythmic humming or vibration and observe if the vehicle tracks straight to ensure the recent tyre replacements have addressed underlying alignment faults.
