Mein Auto: 2004 545i ,2001 X5 3.0
X5 Sunroof

I find that on my 01 X5, when I have the sunroof open and all the windows closed, there is a lot of buffeting at about 29mph. The only way I have found to resolve this is to close the sunroof about an inch, and it goes away completely at all speeds.

Is this normal? You would think BMW would be able to address this problem in their design a bit better.

100% normal with today's aerodynamic vehicles.

There is an area of low pressure above the sunroof that causes the buffeting sound you hear. If it really drives you crazy, get one of those plastic "sunroof deflectors" that many dealers will sell aftermarket. It will stop the buffeting. You can also crack one of the back windows while you are driving.
