2009 Mercedes-Benz C 2.1L Diesel · ET51 ACT

The vehicle remains roadworthy, though the maintenance trend shows a shift toward reactive repairs after years of clean passes. The most recent test in July 2025 at 102,702 miles flagged thin rear brake pads and worn discs. This represents a departure from the previously clean records seen in 2023 and 2024, indicating that consumable components are now reaching the end of their service life. While the car passed, the braking system requires immediate attention. The mileage pattern is consistent with a 17-year-old vehicle, averaging approximately 6,000 miles per year. Between July 2021 and July 2025, the car covered 30,930 miles, showing a steady and predictable usage rate rather than long periods of inactivity. This low-mileage profile suggests less strain on the drivetrain and suspension components, but the age of the vehicle increases the risk of material degradation in rubber parts and metalwork, which is evident in the historical-related faults. A buyer must focus their physical inspection on the braking system and associated fluid lines. The July 2022 test at 73,148 miles revealed corrosion and deterioration across multiple brake hoses and pipes, suggesting the vehicle is susceptible to environmental-related rust. You should check for any further cracking in the rubber hoses or scaling on the metal pipework. Additionally, the 2021 advisory regarding uneven tyre wear warrants a check of the wheel alignment and suspension bushings to ensure they are not causing premature tyre scrubbing.
