Hey guys,
I was recently heading to the airport for vacation and I decided to open my sunroof. Upon opening it I didn’t hear any infamous “machine gun noises” or Clunks that would’ve raised red flags. It was at the point that I parked the car and tried to close the sunroof that once it shut completely I realized one corner (passenger side back corner was raised about an inch or 2... now that I’m back from vacation I’m trying to figure it out and not having any luck. When I try to open it, it acts like it will open but then shuts and goes right back closed. Theirs no way from what I can tell that it’s able to be taken off because I can’t reach the bolts to dismantle being that it’s completely shut. I’ve tried to reset the sunroof.. nothing. I’ve also tried to use force to push it back down in position but I’m afraid to crack the glass. Can anyone walk me through this I’m sure the dealership will take an arm and a leg just to resolve this issue. I only want it shut for not I have no cares about it working correctly. Thanks in advance for ANY advice you might have!

To be honest I never had it serviced nor lubed... at the moment I’m not concerned with it working more so with just getting it to sit flush and completely closed so water doesn’t keep getting in...

It appears that is a problem with the sunroof as there have been several posts of the same thing. Check these posts.
The second post has many others reporting the same problem. Looks like a plastic shoe is a problem.

yup.

That sucker is broken. Welcome to the club.

If it's under warranty, take it back for inspection asap. The dealer will replace the entire assembly to fix it.

---------------------------

If it's not, sorry dude, you're in for a world of pain.

the plastic bushings are available on ebay for $12 a pair, and they are physically impossible to put in. It's a pretty good racket by the ebay company, actually.

If you are not super handy, your moonroof is done. You need to slowly open up the other side while you're watching the roof, and get it into a position where you can snap the broken side into place. Then close the roof and call it good. Until you are willing to either pay thousands for the dealer to replace the whole assembly, or unless you know how to put two quarters into an empty beer bottle, because that's literally the equivalent fix, once you have the $12 bushings in hand.

Fun!

To clarify, when you open the roof you'll see right away the part that is broken, comparing sides. The bearing shaft is also a hinge for the moonroof, which is hinged up and thus won't close. It's harder to describe than it is when you see it. When you pop it back into place you'll see nothing is holding the bearing shaft into the track anymore. But it's good enough to close the roof.

Even if both sides are broken, you can get the moon roof to close. Just be not moving, in your driveway, and go slow to guide it into place. It'll seal up just fine to go to car washes, be in the rail, etc. No biggie. But I wouldn't open it when moving. Not until the bearing triangle pieces are back in place. The impossible-to-install ones.

Thanks for the responses everyone... sad to say Mercedes Benz of Tampa was quoting me over $5k in repairs and labor.. so I went with the only option I had left which was to completely break that piece off and now it sits flush and thankfully the rubber seals aren’t allowing water nor air to enter through it. Unfortunately I had to take that route but it rains every other day and that whoosh of air driving on the highway was driving me nuts. Btw that two quarters in a beer bottle brought tears of laughter to my eyes. You’re hilarious man. Best endeavors everyone !

Hey I have the same problem on my cla 250. Apparently, they use the same panoramic roof. So one side popped and I can't get it down. The biggest problem that I'm facing the roof is not opening I can only open the moon roof. Would appreciate any suggestion I need to get it closed asap cuz it's gonna rain in a few days. Looks like the other side stucked in closed position and won't release the corner which is by the windshield. Should I force it out with a wrench? I'm kinda afraid to do more damage. I used to have the old mercedes and there was a screw located under the dome light to manually push the sunroof down. However, I'm not seing it in my car. Any good advise on how to close without damaging it would be highly appreciated.

@Farsnyc sorry to hear it happened to you to...I had this issue months ago and still til this day haven’t gotten around to fixing it. Not sure if you saw my response above but I broke the back passenger side metal lifter that can be seen in the pics above. Mercedes will take your arm off so I’d try to search European mechanics in your area that are certified and can diagnose the problem further and at a cheaper rate than the Mercedes bens dealer. Please do post your outcome to this forme it could help someone in the future. Good luck man !

Thanks for a quick response man. My problem is indentical the back lifter on the right side got stuck and won't lift down. I'm seing it attempts to slide but something is stopping it. And again I can't even slide the sunroof it simply would not open. Trying to anderstand the concept of it. I can see that lifter located at the other side slides up and down w/o an issue but the othe other side it just moves 2-3 mms and stops. How did you broke that thing it's made of solid metal?

@Farsnyc I tried so many ways to push the opposite side up and nothing would give. So I put a torch to the metal and began wiggling the piece side to side with needle nose pliers until it eventually gave and I broke some other pieces like the plastic bracket in the process.. I basically put a hole in my wallet if I ever get it fixed in the future but I needed it closed cause just like you their were storms coming and a tarp wasn’t an option for me. If you decided to take that route just understand that it’s a quick solution but you will pay more due to breaking more parts. (Won’t need to worry about leaks or air rushing in as long as you get it to sit flush the seals will do the rest)

Thank you for the heads up. My question is, since the sunroof stuck in closed position with one side popping up is that possible to unscrew it from the inside? I'm wondering if there are some bolts holding it in place. Removing all pillars and taking apart the roof from inside would it let me to unscrew the sunroof from inside?

you make it sound like all you need is the Penn&Teller Indy repair shop to hook you up !

So that makes all the overhead buttons either useless, counterproductive or potentially disabling.

anyone think of a way to paint the failure as a "danger to others on the highway" so it becomes a recall over a simple TSB. mebbe the water incursion will lead to side airbag failure???

Is there a Racing option to replace all that **** topheavy junk from the roof, and replace it with a nicely finished, single panel, targa, ? I believe is the style, or is it T top ?


To your Ebay point,

Indeed !
but racket is such a strong word

They are providing Hope.
And, a small plastic talisman, to focus the hope.

You have a 2017 W205 C300. There is a recall for sunroof problems on this model. Suggest you check with the dealer for possible repair/replacement under the recall. If your problem falls under recall is the best fix and would be free.
