2013 Mercedes-Benz C 2.1L Diesel · LT13 KKW

Corrosion on the rear brake pipe and the severe deterioration of the front anti‑roll bar linkage dust covers dominate the MOT record, signalling a persistent exposure to moisture that has not been fully remedied; the latest 3 April 2026 test still passed but retained those same minor items, while a series of advisories over the past six years also flag progressively worn rear discs and corroded rear coil springs, indicating a steady accumulation of wear rather than an abrupt failure. At 104,658 mi the vehicle averages just over 8 000 mi per annum, a mileage rate that sits comfortably within normal usage for a 2013 model and shows no evidence of long periods of inactivity or sudden high‑mile spikes; the regular annual testing cadence further suggests the car has been kept on the road consistently, meaning wear on consumables such as brakes, suspension bushings and springs will be in line with its age and mileage rather than accelerated by irregular use. When inspecting the brake system, feel for a firm, consistent pedal without sponginess and listen for any hissing or fluid leakage around the rear pipe area, as the repeated corrosion advisories imply the pipe may be thinning and could develop a leak under load. Verify that the rear parking brake holds firmly and does not require excessive pedal travel, and examine the rear discs for surface pitting or scoring that could translate into vibration or reduced stopping power; any judder under hard braking or a noticeable pull to one side should be traced back to the corroded pipe or the binding service brake noted on the near‑side front in 2024. The front anti‑roll bar dust covers should be inspected for cracked or missing material that could allow dirt and moisture onto the linkage, and a test drive over uneven road should reveal any clunking, knocking or excessive play in the front suspension that would point to compromised bushings. Likewise, the corroded rear coil springs may have lost some elasticity, so watch for a soft or sagging rear ride, uneven tyre wear or a noticeable dip when loading the vehicle. A thorough visual and tactile check of these components, followed by a professional suspension and brake service, will address the documented corrosion and wear before they develop into safety‑critical failures.
