So my wife just got her new to us 2014 535i. At the dealership we went through everything as this was our first bimmer. Today when she got home she had left the windows down in the backseats. She says she got out and noticed the Windows down. Then she noticed something sticking out of the roof above the window in the rear seat. She states that she pushed it down and the Windows closed. I do see that above each rear window is the outline of something that is about 5 inches long and 3/4 inches wide. I tried to recreate the situation and can't. Has anyone ever heard of this?
