I bought an 2003 Audi A8L with 101,000 miles out of California the right rear window was broken. I replaced the window but there is this rubber part that came somewhere off the door. I looked at the diagram that was on audipages it shows the part its called a plug part# 4DO839492C. I just can't figure out where on the door it goes. I really don't want to reassemble the door without it back in place wherever it goes Lol. These are the pictures any help would be greatly appreciated Thanks...........
