I didn’t observe significant visible contamination, but the inspection was cursory. I didn’t perform any alignment checks or calibration procedures. Could you elaborate on the specifics of your incident?

In my case, the issue persisted even after cleaning. I had to take it to the workshop. They recalibrated the radar sensor, and the problem was resolved immediately. I recommend a professional assessment, as these systems are quite sensitive. It's worth checking out!

I pursued a professional diagnostic assessment. It was indeed a soiled sensor, and post cleaning, the error was resolved. The repair cost was 45€. Thanks for your assistance.

I had a similar problem a while ago with my Peugeot 308. My adaptive cruise control went haywire, and I was getting all sorts of warnings. Was the sensor visibly dirty when you checked it? Did you check the sensor alignment, or consider a radar calibration?
