ok well i just got my car. it has a sunroof on it. i pulled back on the cover in the inside of the car and it like wobbled out of place. im pretty sure its not supposed to do that and its probably broken. i havent opend up the sunroof yet because i didnt want to do more damage but the slide cover thing is probably broken or out of place. it wobbles side to side and it seems it is not in the "slits" of the guidance slits or whatever because it can move up and down and side to side. it can go back but not slide, its all rough.

to better understand this, think of closet sliding doors or sliding shower doors. when the doors wheels falls out of place from that groove on the top and it cant slide anymore, it kinda feels and looks like that.

Another common E46 problem

After a while it will get worse to the point you jam on the brakes and the cover closes

oohh nice.. thank-you.
