2011 Mercedes-Benz C 2.1L Diesel · CM57 HAR

The vehicle is currently roadworthy but the maintenance history shows a worsening trend regarding corrosion and suspension components. While it passed the most recent test in May 2026 at 95,549 miles, the tester identified a new failure on a deteriorated offside front anti-roll bar linkage ball joint dust cover. This follows a period of recurring brake pipe corrosion that has persisted across the last three tests, suggesting that while repairs are being made, the underlying degradation of the metal lines is not being fully addressed. The mileage pattern is consistent with a 15-year-old vehicle, averaging approximately 6,300 miles per year. The record shows steady progress from 82,680 miles in May 2023 to 95,549 miles in May2026. However, a significant lapse occurred between April 2024 and May 2025, where the vehicle covered only one mile in a year before returning for a test with multiple mechanical failures. This specific interval indicates a period of neglect or reactive maintenance where faults were only addressed immediately after failing an inspection. A physical inspection must focus heavily on the braking system and front end geometry. The persistent flagging of corroded brake pipes on the offside front and both rear sections indicates a high risk of future leaks if the lines are not replaced rather than merely cleaned. Furthermore, the history of excessive wear on lower arm ball joints and track control arms in 2025 suggests the suspension components are reaching the end of their functional life. A buyer should check for any play in the steering components and ensure the parking brake efficiency remains optimal after the previous failure has been properly rectified.
