Thank you Loren, I read the bulletin you supplied and my sound is a rattle not a creaking noise, kinda sounds like a clip or something fell off. Guess I'll live with it as I don't want to mess with the described removal procedure. Appreciated your input though.

Oh there are more noise remedies for the sunroof...

There are 4 bolts that secure the roof over and mine had rattled loose. They can be seen from the inside and are horizontal.

I solved my rattle from the sunroof area.  It was two things.  One, there is a plastic rail that catches water and moves it to the drains on either side of the car.  The center of the rail which is made of white plastic was warped upwards just close enough that there was enough movement to touch the lip of the sunroof opening and rattle.  It was worse when it was retracted because then it was hitting the metal stay that keeps the headliner taut.  I took off the window trim front and rear as well as the pillar trim.  I pulled the headliner out of its back hooks and undid about four of the metal stays that fit into holes along the top edge of the roof, allowing it to hang down without removing the whole thing.  I put a small piece of hard cell foam in the middle of the rail and glued it, so it kept the plastic from hitting the sunroof.  If you do it too much, the water will just stay in the center of the rail.  Be careful!  Then I noticed that there is a rubber strip that attaches to the flap on the headliner and this had simply come loose and was flapping around, without it in place, the drain rail would travel back with the sunroof lid and then touch the metal stay AND the rubber strip.  So I glued the rubber strip back in.  I put some sticky felt near where the hooks go into the area at the top of the back window and then put everything back together.  No sounds!
