I have the same thumping noise, sounds like the tire slapping the tar in the cracks. At first I thought it was the load leveling system pumping up. Check this: close sun roof but leave slider open. When noise starts, open your window a bit. The noise usually stops for me. Also if you push up on the front corners of the glass while it is making the noise it should stop. This makes me think that the seal on the sunroof has shrunk up and there is just enough play that the air pressure makes it thump like it does.
I will be bouncing this theory off my local Caddy Service Dept. and will let you know if they have any brilliant ideas.
