2009 Mercedes-Benz C 3.0L Diesel · KV59 WLB

Chronic wear of the front suspension system and emerging structural corrosion define the mechanical history of this vehicle. A persistent pattern of deteriorated anti-roll bar linkage dust covers and worn ball joints has been recorded since 2019, alongside a major failure for a worn nearside front suspension arm bush in 2022. While the vehicle passed its last inspection on 2023-07-22, this test introduced a new advisory regarding corrosion of the rear sub-frame, indicating a shift from simple wear-and-tear components toward more significant structural degradation. The recorded mileage of 125,062 miles over 17 years represents a typical annual average of roughly 7,357 miles. This usage pattern suggests a steady accumulation of wear across all major mechanical systems. At this mileage, the vehicle is in a phase where rubber components, such as suspension bushes and linkage boots, naturally perish, and braking consumables require frequent replacement, as evidenced by the repeated flags for thin pads and pitted discs in the MOT record. A physical inspection of the rear sub-frame is essential to determine the extent of the corrosion flagged in the latest report and to ensure the structural integrity remains intact. During a test drive, the buyer should listen for knocks, pops, or clunks when navigating uneven road surfaces or turning the steering wheel at low speeds, which would suggest further deterioration of the front anti-roll bar linkages or suspension arm pins. Any steering pull or instability under braking should also be noted. The braking system has a history of instability, including a major failure for parking brake efficiency in 2020 and advisories for pitted front discs and thin pads in 2022. The buyer should check for pedal judder during deceleration and ensure the parking brake holds the vehicle firmly on a gradient without excessive travel. Given the previous dangerous failure for exposed tyre cords, a thorough check of the current tyre tread depth and sidewall condition across all four corners is necessary.
