Alright, brought it in today w/my 'regional VW of America' case and took a drive with a tech. Turns out he was the guy that replaced my window seals and channels a year ago. He was like "I remember". We took a drive, he drove, drove the shit out of it, and said "I don't hear anything out of the ordinary for these cars. Is this your first GTI?" I said yes. He said "get used to little rattles here and there. Stiff suspension, 18" wheels, etc. stiff ride. Just the way it is." He continued "I consider myself an honest guy, and its not that I don't want to take the time to fix the problem, but I just don't think there is a problem to fix." He noticed that the rattles only happen on rough roads which he said is normal and he said the window switches were fine and not loose. When I mentioned how many others had reported similar problems on the forums, he rolled his eyes and said "I pay no attention to what anyone says on the forums. They don't know what they are talking about. Half the stuff on there is BS written by guys who have way too much time on their hands. I've been a VW tech for years, know the cars inside and out, drive them all the time, work on them all the time, and your car is fine."
I mentioned that the forums, where no one knows what they are talking about, is where I found out about the felt tape that has since silenced the loud creaking and flexing of the rubber seals against the frame. I showed him. He wasn't impressed.
I left. I'm over it. Maybe I am too anal or sensitive or something. My wife rides in it and says it feels like a limo compared to her car. She thinks I'm crazy. So does VW apparently. So whatever. I came home, washed it, waxed it and I'm just gonna deal, for now. I just can't be bothered with this petty shit with it anymore. All in all, its a great car, so I'll live.
