DS4 Radar Sensor Issue

I've got a 2015 Citroen DS4 with a gasoline engine and 56809 km. I'm having an issue with the radar sensor. Error message in the speedometer, error code, failures in various systems, and a warning light. Could a dirty sensor cause all this? Anyone else seen this?

I had a similar issue on my DS4. Error message and warning lights. Did you check the sensor for dirt or obstructions?

I checked it visually, didn't see anything obvious. But could a thin layer of grime cause such a system-wide response?

It's possible. I just took mine to the shop. They cleaned and reset something, and the problem went away. Saved me a headache. Wasn't expensive.

I took it to a workshop and a simple sensor cleaning fixed it for 45€. Thanks for the advice.
