My sunroof broke again...for the third time. It opens back, but won't tip up at the back any more. It also rattles incessantly.

I tried to get in there to see what might be wrong, but can't even get past the first step. Anybody know how this thing comes off?

Are there any online guides for this? I looked on bmwtips, but didn't find anything.

TIA.

It takes a very skilled shop and technician to properly

fix the automatic sunroof on any car. It's a nuance/feel thing the tech must have.

I've fixed one on an E39 before and it was tricky.

Breaks all the time

I've had the piece represented by the red arrow twice on the left side and once on the right. The piece represented by the blue arrow broke once on the left side. These two pieces are easy to replace - the second time around. It took awhile to figure out the mechanics of it the first time. The piece represented by the green arrow broke once. This concerns me because I'm afraid I might have to remove the headliner and entire sunroof frame. It's my project for today.

I don't know who the genius was for designing these pieces because they're the only plastic pieces and they always break. All the other pieces are aluminum. I hope this Smartguy finds a new career. Either that or I guess BMW always embeds design opportunities to make money.

I have the same problem but am afraid to remove the sunroof myself in fear that I will be stuck with the roof apart and scratches all over the roof.

I inquired in using the repair kit at an indy I frequent, but they said the job would be costly and advised against it unless im really wanting to spend that kind of money. I may try to replace the sunroof seal to see if it will stop the rattling. I miss having the tilt function, but its been over a year and id rather have no tilt and have the annoying rattle go away.

If the pieces are breaking repeatedly, there is a problem elsewhere. I had a similar problem and I made a thread showing the culprit in my case. the job is a PITA, but it is not in the realm of magic. If you have the whole thing apart the toughest part is syncing up the cables again.

Thanks. Very helpul instructions.

The lift guides seem ok. Part of what made it worse this time around was I continued to use the sunroof after I heard the initial snap. I figured it's just another quick repair to replace the red part I pointed to.

I'm guessing I'll have to take the whole headliner and frame down if the part shown by the green arrow broke?

That's right, if you have to replace that part, the sunroof cassette has to come out.

Oops, I thought those were instructions for removing the headliner and frame. Hopefully it's a one person job and a 3-day weekend. I guess I'll learn as I go along.

I've had this problem for year, still do. The piece identified by the red arrow always breaks. It even breaks while I try to repair it and test it. I think part of the problem is the tilt guide which I can't find a diagram on the part. I aligned it once, but I think it wasn't aligned well. If one side guides the lift sooner than the other, it could cause stress on the part shown by the red arrow.

There are dozens of 3D copies on eBay. Not a chance I'm buying another plastic piece, especially a 3D clone. I'm hoping to find a CNC aluminum copy. Anyone seen one?
