Hi guys, first post here. I don't have a GTI yet. Two years ago I bought my son a brand new Passat. Few days later, I noticed some rattling noise coming near the windshield on the right side. I took it to the dealership, they changed the wiper. but the noise was still there. When the VW survey came, I said problem wasn't fixed. That almost got the tech fired. The dealership's service departments manager called me personally to ask me to come back to let him have a look.
He rode around with me, first he said he didn't hear anything, but I knew it was there. Then he used tapes to tape certain sections of where the windshild meets the frame, did that several times until we could isolate the spot. Then he injected some kind of sealant in that area, kept the car for the night. The noise was gone. I asked him not to fire the tech and he didn't. I didn't want a poor kid fired over little stuff like that.
Anyway, I know this is not related to this thread but just wanted to share.
