Peugeot 2008 Radar Sensor Issue

I'm having radar sensor issues on my 2020 Peugeot 2008 with a gasoline engine. The speedometer shows an error, and there's an error stored. Other systems are failing too, with a warning light. Only 21333 km on the clock, so I suspect the sensor. Could a dirty sensor cause these widespread failures?

Sounds familiar. I had a similar problem with my 2018 Volvo XC60. Your symptoms mirror what I experienced. Could something be obstructing the sensor, like mud?

Thanks for sharing. Do you remember if the error messages you got were intermittent? Did cleaning the sensor area fix it, or did it need more diagnostics?

The errors were intermittent, like clouds passing in front of the sun. Cleaning didn't entirely fix it for me. I had to visit a workshop to recalibrate. I'd suggest seeing a professional.

Thanks for the insight. I checked the sensor and it was heavily soiled. After cleaning, the system went back to normal. The workshop confirmed the sensor was the problem. Repair cost was 45€.
