Clio radar sensor error

I'm getting a radar sensor error on my 2018 Renault Clio (gasoline engine), triggering a warning light and disabling adaptive cruise control and collision avoidance. Error memory confirms the malfunction. The car has 130563 km. Anyone else faced something similar? I've checked the sensor visually, but it looks fine.

I have a Clio as well, and I went through something similar a while back. All those driving assistance systems went haywire. Did you check if the sensor is actually clean? In my case, it was just a layer of grime messing everything up.

Interesting! I gave it a quick wipe, but maybe I wasn't thorough enough. When you say 'really clean,' what exactly did you do? Did you use any specific cleaning products or methods? I'm hesitant to start scrubbing too hard, as I don't want to damage anything...

Yeah, just wiping might not cut it. I tried that too. But in the end I didn't feel confident enough and went to a workshop because I didn't want to risk damaging it myself. They told me the same thing, it was really just dirt and nothing more. But it had to be done carefully.

Okay, thanks a lot! That confirms my suspicion that it is a dirty sensor. I'll take it to a local shop. It cost me 45€ but that solved the issue, they cleaned the sensor very thoroughly. Thanks for sharing your experiences, it saved me a lot of time and nerves!
