LandCruiser radar sensor failure

My 2021 Toyota LandCruiser with a gasoline engine has a radar sensor malfunction at 49892 km. Error message in the speedometer, stored error, and warning light. Systems failing. Sensor looks clear, any ideas?

I had something similar with my 2018 Audi A4. Any recent bad weather or off-roading? Did you try a system reset or check the error code?

Yes, some moderate off-road. No recent weather issues. What reset procedure did you use on the Audi? What was the error code?

I disconnected the Audi battery for 30 minutes, but be careful doing that with the LandCruiser. I don't remember the error code. Since you checked the sensor, and it impacts safety, get a technician to look at it with diagnostics.

The technician found the sensor was just dirty. Cleaning fixed it. Cost 45€ Thanks for the advice!
