I just removed mine and there is no adhesive holding it on. It's just clips, push the top and bottom clips out. Then pull on the emblem a little, i used a knife to help lift the emblem up on eachside a little more to get a better grip on it and began pulling slightly and it finally popped off.
Its a 2 piece emblem, the black back piece and the chrome emblem. The chrome emblem slides in place and clips onto the black piece. If you mess with it a little bit the chrome piece should pop off the black piece.
