Gentlemen, we have recently acquired the Z4 specified above, but are having issues with the exhaust, the exhaust flap seems to be open all the time, regardless of mode (comfort, sport, etc...) Is that the way it’s supposed to be? And is there a noticeable difference in exhaust notes between the different driving modes on the 4 cylinder engine?

Not sure. Stuck open is better than stuck closed.

The only problem with stuck open is motorway drone.
