Sorry Norm, no experience here. I had to clean out the silicone grease on the sunroof tracks after spinning off track into a sand trap, but I didn't adjust anything. There isn't much room to work in there.
It's probably a common dealership request to adjust the sunroof. I think spec is 1mm below the roof in the front and 1mm above the roof in the rear. Try talking to the mechanics at your local dealership.
