Sunroof problem
 

In my e70 one of my friends accidentally hit it and the front half of the shade on the left side is raised more than the other (it should fit flush). The sunroof still operates normall except when calling to retract the shade from closed to open it makes a very loud click. I was wondering if anyone else has experienced this and what did you do? I'm really looking to avoid getting help from a dealer with this one.

Warranty?

$$$$$

if you have a warranty I'd not really get into a whole lot of detail on how it MIGHT have happened.
