2004 Mercedes-Benz CLK 2.7L Diesel · SF54 WFZ

Recurring structural and mechanical degradation, specifically regarding the braking system and suspension, defines the history of this vehicle, which most recently passed its MOT on 6 January 2022 with no defects recorded. While the most recent outcome appears clean, the preceding years show a pattern of significant failures, including major issues with brake pipe corrosion and front brake disc wear in late 2021, as well as a fractured coil spring in 2020. This trajectory suggests that while the car has been brought back to a roadworthy state, the underlying components have required substantial intervention to address wear and environmental corrosion. With a recorded mileage of 90,646 miles over 22 years, the vehicle has averaged approximately 4,120 miles per annum. This low usage profile, while seemingly modest, often subjects older vehicles to prolonged periods of inactivity, which can exacerbate the corrosion of metallic components such as brake lines and suspension springs. The MOT history confirms this, as multiple advisories and failures were linked to corrosion and surface degradation rather than high-mileage mechanical fatigue. Prospective buyers should be aware that low mileage does not equate to immunity from the age-related deterioration of rubber bushes, seals, and structural metalwork. During a test drive, pay close attention to the braking performance, as the vehicle has a documented history of corroded brake pipes and worn, scored discs. Any sponginess in the pedal, a lack of immediate bite, or grinding noises when slowing down should be investigated, as these could indicate that the braking system has once again begun to deteriorate despite the clean 2022 pass. Additionally, listen for any knocking or clunking sounds from the front end, particularly when traversing uneven surfaces or speed bumps, as the vehicle has previously required attention for ball joint play and coil spring fractures. The steering and suspension geometry should also be assessed for any pulling to one side or vagueness, which may point to lingering issues with the track rod ends or suspension arm ball joints that were previously flagged. Given the history of brake pipe corrosion, a physical inspection of the lines underneath the vehicle is essential to ensure that previous repairs were comprehensive and that no new oxidation has developed during the time since the last test. Any evidence of fluid weeping around the calipers or uneven tyre wear patterns should be treated as a warning sign that the suspension or steering alignment requires professional adjustment.
