Just picked up an E55 AMG

Sorry to hear about the issues. Hopefully an Indy can point you in the right direction. As for the Pano Roof. Have you tried a full reset? Not sure it will even work for you since you said it's "dead", but I've been compiling some "tips and tricks" since I just got mine a few months ago. This may help a bit. You can just search for pano or sunroof in the doc.

Wiki would be better, but Google Word Doc is second best.
