Asked by for the 2007 BMW 328i
The sunroof has an initializing process.

Press and hold the sunroof in the "lift" position the roof will go up, keep holding for about 15sec and then the roof will move another half inch or so up

Keep holding the switch in the lift position, the roof will then close, then slide open all the way, and then close again

The process is then complete

Do not release the button untill the process is completely finished, else you would have to start over again
