2004 Mercedes-Benz C 2.1L Diesel · YK04 ABP

The vehicle most recently passed its MOT in June 2024, although this followed a failure just two days prior due to a fractured offside front coil spring. The overall maintenance trend is concerning as it indicates a progressive decline in the condition of the chassis and suspension. Specifically, the recurring advisories regarding corroded rear brake pipes, which have appeared consistently since March 2022, suggest a chronic issue with the braking system's structural integrity that has not been permanently rectified. With a recorded mileage of 124,150 miles over approximately 22 years, the vehicle has averaged roughly 5,643 miles per year. This is considered low usage for its age, which generally implies less mechanical wear on the engine and drivetrain. However, low annual mileage often indicates periods of prolonged standing, which can be more detrimental to certain components than regular use, particularly regarding the degradation of rubber seals, the accumulation of moisture in the exhaust system, and the acceleration of surface corrosion. Prospective buyers must prioritize a thorough inspection of the rear brake pipes. The MOT records mention these pipes being covered in grease or other materials, a practice often used to mask corrosion or slow its progress, which should be viewed as a significant warning sign. During a test drive, be alert for any clunking or knocking sounds from the front suspension, as the recent coil spring failure may be indicative of wider fatigue in the suspension bushes or the remaining springs. Additionally, check the nearside rear tyre for uneven wear patterns, which could point to underlying alignment issues or worn dampers. Given the vehicle's age and low usage profile, further physical checks are essential. Inspect all tyre sidewalls for perishing or hairline cracking, as tyres can become unsafe due to age regardless of remaining tread depth. Examine the brake discs for heavy corrosion or evidence of binding calipers resulting from inactivity. It is also critical to verify the service history to ensure that engine oil and other vital fluids have been changed according to calendar intervals rather than mileage alone, and to confirm the current health of the 12V battery, which is prone to failure in vehicles that are not driven frequently.
