The worst thing just happened - sunroof

Alas, my bmw adventures never cease. It's as if it's the ultimate failing machine.

Got out of the gym, was sweaty, decided to roll back my sunroof

LIKE A ****ING MACHING GUN
It starts grinding the horrible noises of death, oh how my heart sank as I knew I'd be in for another costly repair.
Sunroof managed to get cockeyed out of the roof, and be stuck there. No amount of pushing up, or down, with any combination of forward/backwards sliding of the sunroof fixes the problem.

Ugh. Has this happened to anyone else? What do I need to replace, is there a procedure to this?



Pictures. One is the side of the roof indented inside, the other side is lifted up ajar.
The picture inside the car is the slider mechanism I believe.
HELP!

About to go on a 650 mile trip, immediate responses are greatly appreciated and I will forever be in your debt.

Ugh. Mine started making the grinding on the top of the windshield just behind the driver's side visor and this is 99% certainly the worm drive cassette. See the link to a forum below which explores this in greater detail along with any other issues that are related. The guide for the metal worm gear that operate the sunroof is plastic and eventually seems to crap out. I've found it's worse in cold weather and each time I open my sunroof I wonder if it's going to do exactly what your has done. Good luck!

Thanks ebeez. So I'm not going to have to buy anything?
Also my sunshade has been crooked and difficult to out back for some time. I can still pull it back within about 1-2 seconds, but it doesn't slide back like it would on a new car, some of the little clips on top are missing. Could this perhaps have expedited my problem, or perhaps made it worse? If some part of a clip got stuck back there

It seems I must locate worm rail and hold it back in place.. From what I read in that post and a video on YouTube, it seems the hollow retainer that the cable goes into breaks. So all I must do it locate the cable, and repair the 'casing'
Is this correct?
Thanks again

I am not sure if you will or won't have to buy anything -- I haven't yet performed this surgery myself. Just read the stories. But it did seem like with some work (and it does look daunting) pieces could be reassembled. The shade seemed to be a pain for people as well--clips snapping off and then sending the sunroof off its track or jamming it.

You probably won't know if you have to buy parts until it's all apart.
