Hi, is there any DIY on how to replace PDC sensors on the rear bumper. I have seen silly easy replacements on other BMW models (just pry off some plastic) while I have read that the bumper has to come off on the X3. Another post said just get your hand under the bumper and wiggle it loose.

Appreciate some input since I do not have the car available to check right now. Thinking of getting used sensor(s) via eBay.
