I am the owner of BMW X5 in China. I found this problem at 170KM/H and feedback it to distributors. Now the after-sales department has given the solution, hoping to help you.
This means that the rubber strips on the top of the front windshield are too narrow to be tightly sealed. Now special tools are needed to support them according to the coordinates in the drawing, and then special adhesives are applied to bond the rubber strips and the roof.
