2011 Mercedes-Benz C 2.1L Diesel · KN11 LUZ

The vehicle is currently in a state of poor roadworthiness following a significant failure in December 2024. The mechanical maintenance trend is sharply worsening, moving from minor advisories to a comprehensive list of critical safety failures. The 2024 test at 192,304 miles revealed a fractured offside front coil spring, a fractured road wheel, and tyres with exposed cords and structural bulges. The inability to test brake performance due to the hazardous condition of the wheels and tyres indicates a neglect of basic safety checks prior to testing. The mileage profile shows a period of extreme usage, particularly in the last year. Between October 2023 at 110,999 miles and December 2024 at 192,304 miles, the vehicle covered over 81,000 miles in just 14 months. This rapid accumulation places immense stress on the high-mileage drivetrain and suspension components. While the car maintained a consistent usage pattern of roughly 12,000 miles annually previously, the recent surge suggests high-intensity operation that has likely outpaced standard preventative upkeep. A buyer must conduct a thorough inspection of the underbody and braking system. The history shows recurring corrosion on brake pipes noted in both 2023 and 2024, suggesting ongoing environmental damage or grease buildup that hides further decay. The persistent oil leak mentioned in every test since 2022 requires a physical inspection to determine if the source is a minor gasket or a more serious engine seal failure. Given the fractured coil spring and fractured wheel, the structural integrity of the suspension geometry and the mounting points must be verified to ensure no stress cracking exists from the high-mileage impact.
