2008 Mercedes-Benz C 1.8L Petrol · KW57 AOR

Persistent issues regarding structural corrosion and suspension degradation define the mechanical history of this vehicle, punctuated by intermittent electronic faults. While the most recent MOT test on 19 December 2025 resulted in a pass with no defects recorded, the preceding years reveal a recurring pattern of failures and advisories relating to the exhaust system, coil springs, and ball joints. This oscillation between clean passes and significant failures suggests that the vehicle requires frequent remedial attention to maintain roadworthiness, with the 2024 failure specifically highlighting a fault with the supplementary restraint system, an issue that also appeared as an advisory in 2022. With 135,088 miles recorded over eighteen years, the vehicle has accumulated an average of approximately 7,505 miles per annum, a figure consistent with standard usage. This consistent annual mileage indicates that the car has remained in regular operation rather than suffering from the complications associated with long-term storage. However, the cumulative stress of this mileage is evident in the repeated flagging of suspension components, including Macpherson strut ball joints and anti-roll bar linkages, which are typical wear items for a chassis of this age and complexity. Prospective buyers should conduct a rigorous inspection of the undercarriage, specifically targeting the subframe and suspension mounting points, as corrosion has been a persistent advisory since 2020. During a test drive, listen intently for any metallic knocking or clunking sounds emanating from the front axle when traversing uneven road surfaces, as this may indicate renewed play in the ball joints or bushes that were previously noted. Furthermore, verify that the parking brake operates with consistent resistance, as a weakened system was flagged in 2022, and ensure the vehicle tracks straight under braking to rule out lingering issues with the brake discs or binding calipers. The electronic integrity of the vehicle warrants careful scrutiny, particularly given the history of the supplementary restraint system warning lamp. Confirm that all dashboard warning lights illuminate during the ignition cycle and extinguish promptly once the engine is running; any hesitation or illumination of the airbag light during operation suggests a fault that may require specialist diagnostic equipment to rectify. Additionally, inspect the exhaust system for signs of further corrosion, particularly at the mountings, and check the tyre sidewalls for the cracking or perishing that was noted in the 2024 test, as these rubber components can deteriorate regardless of the vehicle's mileage.
