Looks like something had hit the back of the sensor as part of it had sheered off revealing some of the wires.

Thanks for this! Gave me the peace of mind to change.
Update, for anyone else searching: I only had to remove the once piece - the black plastic "underbonnet shield",the 12x8mm bolts, to easily get access to all 4 front parking sensors. 2013 X1 E84 3.51 MSport.
Got the new parking sensor approx $40 off a car parts site, wrong color, but a dash of the touch-up paint that came with the car, and it looks and works perfect.
Suggestion: paint parking sensor prior to install, two coats, drying in e.g a clamp in the horizontal position, so the paint "sits flat" as it dries, near indistinguishable from factory.
