CayenneS2083

I backed into a car today getting out of my driveway, somehow i didn't even notice it. Anyways the rear bumper only has a small scratch on it but it is completely out of alignment and the lights over the license plate fell off. The bumperettes are pretty beat up though. One thing that is very strange though is that exactly in the middle of the bumper, under the carrera script it now has like a little nipple. It looks perfect like if bumper came like that but i know it didnt. I pushed in the area to see if maybe there is a screw or something under it that would of caused it with the hit nut there is nothing, anyone know what this is? Do you guys think i would need a new bumper?
