Go to the tech section, there are numerous threads on this. I would check the sunroof drains first (if you have a sunroof), then unscrew the marker lights and use some silicone around the wire holes. A few people have had leaks around the black pastic trim and the channel for the roof join, but that is rare, although it will go right down the pillar if it leaks. Lastly,some of those that have had a few windshields have had sealing problems after the third or fourth one.
