Looks like my suspicion is confirmed. Looked up the part number for the cable, got this:

I didn't notice anything broken. One of the support arms for the sunroof headliner was bent, and both sides were just pointing up rather then down, in some sort of track, like I'd assume they should be. So I'll get a new headliner assembly, but that has no effect on my main problems.
In the lifting assembly, I didn't see anything cracked. The arms seemed slightly bent in the front where they are metal (look at the pic of the parts on the shelf, the two long arms that are plastic at one end and metal at the other). So maybe that was the source of one of the issues. But as far as being able to move the sunroof around so much, mainly up and down, when it's in a certain position, I can't figure that out.
I would just replace the main lifting parts (the plastic/metal rails and the pivots things, see the pic of the parts on the shelves), but it appears those two pivot parts (see the close up pic of the parts in the shelves) are either not available, or only come attached to the cables.

Part #11 points to what I need, but lists it as the cable. #12 through #16 are the various bushings, rollers, and pins that attach to it.

I disassembled most of the sunroof last night. There seems to be 2 main systems of components. The motor and cables being one, and the lifting mechanism for the tilt feature being the other. The motor and cables seem to be operating perfectly. I still have these parts in the car.
The lifting mechanism is also the part that bolts to the sunroof via 6 torx screws. It involves 2 main brackets on each side that bolt to the sunroof, and a pin/pivot assembly that connects those brackets to the cables.
It's hard to explain, so here are some pics:

Both of these articles were very helpful ... the first is more to see how it all attaches ...Leave a comment:

You should try to post up a couple pics. Its hard to visualize the extent of the damage.
I have similar problems. At least one of the front bolts that attaches the panel to its bracket came out on mine and got stuck in the tracks. I have to push up on the front of the SR to get it to close.
I vote to fix it if its feasible. If it needs a whole new cartridge, then slick top fuh razing.Leave a comment:

That would be great, thanks!
Yes, my sunroof was whistling due to either a bad gasket or misalignment. The Bentley manual has the specs, I think it's 1-2mm under in the front, 2-3mm over in the rear, or something like that. Unfortunately, my entire assembly is so jacked up, that the sunroof actually moves up and down a good 1/4", in any position, without me touching the button. You can literally just push up on it and the whole thing moves. So even if it is aligned in one position, it just moves around and whistles anyway. There are literally parts that are broken, bent, or missing all together in mine.Leave a comment:

I found a really good write up on the web regarding sunroof installation, repair, and such.
A guy was redoing his headliner and shows how it all goes together. My guess if the sunroof is "whistling" then it has to do with the tilt mechanism i.e. your sunroof has a gap letting the flow of air in to create a vortex of musical excitement.
It could just be a few parts that you have to swap out or I understand whistling can happen with a bad gasket seal. Let me see if I can find this article and then post it up tonight.

Actually, I just went through realoem and if I purchase every mechanical part of the sunroof assembly, besides the motor and cables, it comes out to a little over $300 through ECS Tuning. That sounds a little more appetizing then replacing a roof.
But, I've never built the sunroof assembly from scratch. Anyone have any experience?Leave a comment:

Major sunroof problems
A few years ago, my sunroof started whistling. I adjusted it, but could never get it perfect. Fast forward to about a year ago, I gave it another go. I don't know what I did, but when I took it for a test drive, it was screaming. And it's all been downhill from there. Something came loose and/or broke, so you could get it so it wouldn't whistle when you put it in the closed position, from the tilt position, but it would whistle if you put it from the open to the closed position, or vice versa. Then it started jamming up, and leaking.
And it kept getting worse. Now, there's random rods and brackets bent, tearing up the sunroof headliner panel, and water literally pours in. If it rains, you're getting very wet. The drains are all open, it just runs in past the gasket because it's so far misaligned. The entire thing is so fucked up, its way beyond simple repair or adjustment. I'm baffled that it still works and hasnt crumpled up and self destructed.
So I'm curious what you guys think my best course of action is. I see three options:
1. Buy all new sunroof parts, (probably close to $1000 worth of shit?)
2. Cut a sunroof cartridge our of another car and put it on mine.
3. Cut my roof off, install a roof off a parts car with a good sunroof assembly.
I'm tearing the car down to do some serious front end rust repair (frame rails, shock towers, etc...) So #3 doesn't scare me too much, but it will add a few hundred hours of work to my winter project, and overall costs will be higher (paint).
Has anyone done any of the above 3, or have a recommendation for another option?
