hey guys. i the the owner of a f30 320d and since the cold weather arrived my parking sensors started acting up. they seem to beep continuously like something is really close when nothing is there. this happens intermittently. sometimes all 8 sensors, sometimes only 2, only the rear one, only so front ones and so on. after the car get worm the work just fine until it sits in the cold then its stars all over again. its not dirt or ice since the look clean. is water getting somewhere. the beep seems like a two tone beep.

Thanks for your help.

Wipe them off even if they look clean, could be a software issue is it isn't that... regardless if the cleaning doesn't help go to dealer

I had the same issue - the sensor was defective and required replacement. Fortunately, the car was under warranty and it was fully covered.
