Mercedes GLE Radar Sensor Issue Resolved

I'm driving my 2023 Mercedes GLE with a gasoline engine, and suddenly an error message appeared in the speedometer. It has 288130 km on it. I scanned it, and the error memory indicates a problem with the radar sensor. Now, collision avoidance and adaptive cruise are not working, and there's a warning light. What could be the issue? Could it be a dirty radar sensor? Has anyone else experienced this?

A malfunctioning radar sensor can indeed cause the symptoms you describe. Have you checked for any physical obstructions or damage to the sensor itself? Was the radar subjected to any impact?

Obstructions, like what exactly? And damage? Where exactly am I looking? Is radar calibration needed after cleaning?

Obstructions could include accumulated dirt or debris. As for damage, visually inspect the sensor housing for cracks or misalignment. The error memory points to a sensor failure. I suggest consulting a qualified technician. Radar calibration might be necessary after replacement.

I checked the radar sensor and it was caked in mud. I cleaned it off, and everything is working again. It cost me 45€ for the cleaning. Thanks for pointing me in the right direction.
