A couple of observations which I have not found on the other sunroof threads may be of use to somebody....
If your sunroof glass is not clamping down onto the rubber seal when the manual winder handle is in its stowed position, you can adjust it to take up the slack.
I guess the reason for the reduced clamping pressure is that the springs stretch slightly. If you undo the two bolts holding the winder gearbox in place you can drop it down to disengage the drive gear and turn it one tooth back for a fresh bite, then bolt up again. This then gives you your full pressure on the seal when the handle is locked and seated in its park position. Obviously don't take such a big bite that you overstrained the mechanism.
I cleaned the rubber seal and gave it a smear of Silicone Grease. You should avoid Vaseline or similar as it will attack rubber.
The other thing I found on the rear sunroof was that the drain pipes were routed in the wrong place, the headlining was crushing them flat against the roof which restricted the flow, but more importantly lifted them up above the level of the top of the sump/tray water level so it dribbled down around the gearbox and handle or over the top of the drain pipe connecting trays. I warmed the tubes up with a heat gun to get them off the connectors and then pushed a bit of 10mm dia. stainless up warming the flattened bit to get the stainless in, and after it was there, warming it again to reform the tube.
The bolts holding the tray and the tray holes are rusty so they have been cleaned up painted and reassembled with lots of copper ease.
