There's an official bulletin from Mercedes for those defective trims. Just replaced mine under warranty last week.

apparently this happens from the front door coming lose and becoming misaligned and snagging this trim. I am going to personally tighten that bolt (I'll post the video from a service department showing it when I get a chance.

Mine wasn't loose and still the weather trim broke because of its poor quality.
I believe you are talking about a different issue, the one about the loose hinge screw:

IDK both issues seems conflated with the same problem

Had the same issue with the weatherstripping and door being loose. Thanks for the info. Dealer needs to replace the parts but going to try and tighten the doors myself. Some BS if you ask me. Wouldn't think a 50k car should have these problems.

I think it's both. I have heard a weird creaking in the b pillar area recently when entering my driveway that I never noticed before.
My car doesn't technically fall under the code I guess - but it's right on the date cusp so maybe the cut off is just a little gray.

They aren’t sure if the door misalignment is the cause of the creaking but the tech did confirm he heard something. They mentioned it could potentially be in the headboard area as that is another complaint for this generation? Not sure, but they confirmed they’ll find it and take care of it. Will follow up with what they say.
I also was hearing the same creaking in mine from the B pillar. Also had the issue with the weather stripping. My car is currently stuck at the dealership as they wait for the parts to come in. I dropped it off Monday, should hopefully have the car back this Thursday.

So I got my car back. The weather stripping is fixed and they realigned my door to ensure the same issue doesn't happen again, however the creaking from the B pillar area is still there. They said they didn't hear anything when they took it on a test drive, however you can still notice it when driving slow over speed bumps. Going to try and get a solid video recording of it to then send to the service advisor to see if they can try and pinpoint the issue again.
Other than that, if anyone else takes their car into the dealer for this same weather stripping issue make sure they order the chrome/gloss black trim that goes at the bottom of the window for the rear left door. As part of the repair for the weather stripping they have to take that piece of trim off, and when they do it has a very strong chance of breaking the clips so the original piece can't be put back on. So essentially this repair requires 2 parts to complete. I've included the part numbers below:
Sealing Rail - 206-730-31-00
Window Trim Molding - 206-690-67-00-27

Noisy door seal
Hi. I just purchased a C200 with 5000km on the clock. Virtually new. It has noisy doors/seals and very annoying. Tried to sort it out myself ... I knew that if I left the doors ajar, the noise stopped. Took it back after a few weeks, expecting the door seals to be replaced, but they sprayed on WURTH Rubber Care. Seemed to fix problem for a few days, but now the noise is back. Not a permanent solution. Very poor for a new C Class Benz! Any one have other solutions.

Purchased my C300 in August 2022. Within just a few months the weatherstripping on the front edge of both of the rear doors tore as shown in the pics in this thread. In late 2022 the dealer replaced the weatherstripping on both doors so I figured the problem was resolved. Well, today I noticed the weatherstripping on the driver's side, rear passenger door is again torn. I'm taking the car in for its annual maintenance later this month so I'll point it out then. Wondering if this will be an ongoing issue with this car. I mostly drive the car alone so the rear doors don't get opened very often and I've only driven about 10-11,000 miles since the weatherstripping was replaced.

Seems Mercedes has own solution for seals, based on Krytox GPL-105. MB part number is A0009893660. Same thing is also available for VAG cars, and it's cheaper. Part number G052172A1.
So order either one (MB, VAG or Krytox GPL-105) and use this for all door seals. In my case most noisy one was actually the one mentioned in this topic, on the b-pillar outer trim.
Use very small amount of this "grease" and spread it over the seals using some sponge. It doesn't need much.
Now best thing is, that in theory it's one time application. Do it once and you never have to do it again, unless... someone will wash your seals with i.e. alcohol based cleaner or uses some kind of silicone on it.
Seemingly MB is using it in factory and itshould last, but again, wrong treatment of the seals will wash it off eventually and cause creaks.
Oh, and before applying this wash your seals carefully with something based on alcohol, to remove of remainings of this Wurth or anything else you might've used on the seals vefore. Once washed just apply GPL-105 and enjoy silence.

Please tech a look at my post https://mbworld.org/forums/c-class-w...-sticking.html
I wasn't aware of this bulletin. Is this the misalignment it is referring to?
