sunroof wont fully close

went to shut my sunroof on my p38 today and it slide folwards fine and the as the roof slides up to fully close the pasanger side just stayed where it was. this is leaving me a 2 cm gap for the lovely british weather to enter, any ideas why gents?? or how to sort it....help!!

You say the passenger side, so the drivers side is free and not sticking, so the roof is scewwiff, (out of alignment) open it all the way (if its some kind of ratchet system and on rails when its open all the way back try giving it a push on the passenger side, forcing it back on the rail and track, it might realign it up again, other than that you have something stopping it from fully closing, check that out, it could be anything, a wire on the inside or even the cloth has come lose and is dragging along and caching on the window as it closes, take a good look at it as you open and close it a few times, (is the motor still trying to close it up when its stops fully on the drivers side?) you may have to take it apart to investigate it, i know nothing about the sun roof though, just a few suggestions for you to try, good luck

do you mean sticky from one side ?
don't ever push it to close by hand ... it can cause damage in the electric system ...

If you need to close the sunroof manually you can use the tool normally located in the glovebox - then remove the light assembly console located on the roof. This will expose the motor for the sunroof. Use the tool to close the sunroof.

The fuse is number 13 if you need to check that - located inside the cabin.

iv just got on to my dealer and they want £1400 to put it right. thinking it will stay as it is for a while.

The following question was asked on the rangie.com list and was answered by Martin Saul.

Can anyone help? My sunroof has crappedout. It'll open about 3/4 of a inch and then just stop. The reverse position (window on a slanted crack) works fine.

Hmmm. Does the sunroof just stop and perhaps twist? Heres what I think has happened - I have seen it on a couple of vehicles.

Try this: First a little exploratory surgery. Open the roof as far as it will go, climb up on top of a bench (or similar) and look from outside the top of the vehicle. and see if you can see the ends of the tracks (particularly the drivers side - which ever that is) There are two tracks that the sunroof slides in, in them are a couple of runners, trolleys if you like, and they in turn hold the sunroof up. Now, at the ends of each of the runners is black plastic mouldings (end stops) that stops both the sunroof limits and the sliding sun blind. It is secured by a single screw.
What happens: The sun blind is slammed shut it breaks the black plastic mouldings and then the next time you close the sunroof it simply runs of the ends and jambs.

If this looks like your problem, take heart its not that bad to fix.

The fix: Working from the inside, close the sun roof and remove the two interior trims that cover the tacks from the inside (the are about 7-8 inches long and just clip on. Next Mark the position of the slider assembly to the glass (pencil or a small scratch will do) then get one of those bastard "torx" drivers and loosen the glass from the slider assembly -just loosen them no need to take them out. Open the sun roof just to the point of jamming but not tight. using a flat blade screwdriver "assist" or guide the runner back into its track. Don't push the glass, it is the runners at fault.
When you get the runners back into the track, open the roof a little more but try to get the glass centred again, finger tight the torx and close the roof. when closed the glass will self align and tighten the torks (just nip them up they are only holding glass for goodness sake - tighten to "just right"Nm).
When you close the roof for the first time just do it slowly in case the glass has slipped forward or the runners are forward of the glass (you will see where they were by the dust pattern on the glass).
If The black plastic moulding is broken beyond repair you will of course have to replace it but one the couple I have seen, take the screw out and the moulding and with a but of careful "superglueing" may go back into service. It may be possible to engineer a backup block of PVC, or similar to assist the moulding.
