I have a B4 so i don't know how the B3 molding is secured on your car, but...if it's on there with that double sided foam tape stuff you can just leave it out in the sun for a bit, or heat gun it and then run a piece of fishing line in a sawing motion under it. If it's in there with the little plastic rivets i don't know how to get it off without breaking those off which would leave holes in the body.
