Mercedes C Klasse Radar Sensor Issue

I had similar sensor failure symptoms with my C Klasse. A radar sensor malfunction can trigger a cascade of errors. Have you checked the sensor for obstructions or dirt? That's a common cause of these sensor problems.

Thanks for the insight. I suspected dirt. Can you tell me where the sensor is and how much disassembly is needed to reach it? Also, were your error messages exactly like mine?

The sensor is usually behind the front bumper, and you might need to partially disassemble the bumper to reach it. A workshop visit might be best if you don't have the tools or skills. They might just need to clean the sensor. My symptoms and error messages matched yours. For me, it was just dirt, but finding the exact cause can be hard without diagnostic equipment.

Thanks for confirming the sensor issue cause. I'll book a workshop appointment to inspect and clean the radar sensor. Cleaning the sensor for 45€ fixed everything. The error messages are gone, and all systems work now.
