Re: rattle pano roof
Cycle the roof one time and see it that helps. It helped my 11.
Also, there is a TSB out there about setting/adjusting the panes of the roof at a prescribed "depth", and some adjustment may be necessary.
I know you said you checked the fasteners, but did you actually push up around the perimeter of the entire sunroof? I would do that for sure!
