Parking sensor
 

A UFO flew sideways out from under a semi and popped my front bumer. ('12 650). I was able to buff everything out but one of the parking sensors was knocked back into the bumper. It looks fine but there's no way to get to it to pop it back in. Does this require bumper removal or is there and easier way?

take off the cover off and reposition, not that bad to do.
