Where the sensors are inserted into the Bumper, use an old Toothbrush with soapy water to clean & try, " No, this is not a wind up"

TWR's right it's 'not a wind up' the sensors need to be kept quite clean or you get spurious alerts like this. I found out this when some moron stuck a chewing gum over one of mine!!
