sunroof has stopped working/opening
well I guess my yellow could has got annoyed that I got another coupe in the drive and stopped the sunroof from opening.
I opened the inside cover to the sunroof and then went to open the sunroof and all I get is a click. The inside cover wouldn't close either unless I full the fuse and put it back in again. I have tried opening it again and then trying to open the sunroof and same problem. back out and pull the fuse and put it back in.
Any idea?

What, is the "search" button on the other side in the UK? 
When you have the sunroof and shade completely closed, keep holding the button to close it an additional 10 seconds after everything's closed. That will re-synch things. I have to do it several times a year now, like clockwork.
Like I said, though, it sounds like you have something more complicated, but it wouldn't hurt to try the easiest thing first. Good luck.

I drive a Toyota Hybrid...
yup.. resync it... try it first.... forgot the step, think you need your car key and your person in the car in order to re sync it without the dealer help

Didn't think it would, but thought it was worth a try. Sounds like a sensor may be on the fritz, and it's reading that the sunroof is closed until it's reset by removing the fuse.
Sunroof repairs tend to be very expensive, from personal experience, but you may get lucky.

sun roof now fixed. I just kept on resetting it, pulling the fuse, pushing it and adding wd40 and now it works perfect. once it was open I added grease to the runner.

Actually,... rubber seals on pano don't like WD40,... use silicon lubricant spray.

The SAM measures the current drawn by the sunroof motor to determine when it has hit a stop. If the sunroof sliding surfaces are poorly or improperly lubricated the SAM will think any binding that causes a current increase means the roof is at the mechanical stop.
Because the sliding portions of the roof are exposed to the weather the lubricant has to be water tight as the Southern end of a Northbound duck during landing. It also has to stay put, and reduce the friction by about 75% from dry.
You can use silicone spray, lithium grease, WD-40, Vaseline, or Astroglide but none of them will properly lubricate the roof. They will cause excessive wear and not last very long.
The proper lubricant is A 000 989 36 60(or what ever has been superceded) but it is expensive. I had to take MBUSA to the OSHA woodshed to get the MSDS for it. Turns out it is from Dupont. Krytox GPL 105. Spacecraft stuff. You can get it on Ebay too! Krytox is a lubricant that is chemically inert. It won't rip, rattle, tear, run down at the heels, stink, or smell bad. It is safe to use on all seals and sliding surfaces.
I put it on with a gloved finger, or a dispenser bottle with a steel needle tip. Thinner viscosities in GPL 104 and GPL 103 are better for needle application. There is also a paste form GPL 205 that is good where you need a full bodied lube.
I am not sure what you do with a sunroof in the UK, anyhow?

My glass roof wouldn't open after I had left it at a shop for a week. I just gave it a good push while holding the button to open it and it opened and worked fine after that.

When I serviced my sunroof i bought it from here (dead link)
I don't know if it was the cheapest place to get it from but it worked and uses the correct lube. BTW it fixed my issues with the sunroof being noisy and slow.

Samaritrey gave the best advice. I personally used a white lithium grease that completely cleared up the slow movement and stopping issues. The piece that really needs lubricant and high grade machine oil (on the hinges) is the wind deflector in the front. On the panoramic roof, it is spring loaded and requires a lot of force to lower it.
I recommend you NOT use WD-40. I love the stuff but it is NOT technically a lubricant and will only provide limited success long term.

Actually, Moviela gave the best advice for Dupont Krytox 105,... thats liquid Teflon,.... and is exactly what Mercedes-Benz rebrand as their own part,... also good for any squeaks at rubber seals, seat springs, etc,...
The lubricant that Samaritrey recommended is for older Mercedes with regular size sunroof and should be fine for the W203 sedan that he has. But our CL203 SportsCoupe with the large pano sunroof that put huge strain on the pano motor and gears when they're not properly lubricated,.... needs the best lubricant money can buy,... and that's Dupont Krytox 105.

Yeah you want to use the OEM/OES grease I emailed that place and got a PN which was the same one that is recommended for our cars so I bought it. You can get the OES stuff for cheaper after some research but just make sure you get the correct stuff that’s the important part especially for coupe owners.

Received my order of DuPont Krytox 105 today and decided to fire up WIS to locate the maintenance document for the sliding roof.
Attached is the screenshot for whoever needs it.
MB refers to the grease as Klueber Polytub GLY 801 with part number A 001 989 84 51.

Thank you soo much! Great -- I reset and now I'm good to go... just gonna get the Dupont Krytox 105 before using! Just to think, I paid $60 to the dealer years ago after I had the battery changed and the roof wouldn't work -- he just pushed a button for ten seconds.... that's over 20k an hour, lol... Anyway, my fault for being ignorant -- now I know where to come for answers!
