Carbon Roof Making Noise/Creaking(Rattling)

[JDUni1]

Hey guys, looked around a little bit and couldn't find anything on these cars having issues with the carbon roofs yet. Car has ~1900 miles, and over the past week I have noticed my carbon roof starting to creak/rattle. And it has been getting progressively worse. At low speeds its very noticeable due to quieter road noise. So, is this common or expected with a carbon roof? Any info would be great.

I haven't heard this one yet. Go to dealer and get it checked out. It should not be creaking. They may need to tighten it up.

What do you mean the roof is making noise? Do you mean where the roof meets the doors? If so, that's door seal noise and can be mitigated by greasing the door seals or opening/closing them a bunch.

There's no parts on the roof to creak/rattle, so I'm trying to understand. Is it coming from where the pillars meet the roof, the map lights? etc.

The roof sounds like it's creaking at the locations where is bonded/bolted to the body. Right above the rear sets. Pretty sure it's not the door seals. I plan on taking it to the dealer to have them look at it. I was just curious if anyone else is having this problem.

+1. This shouldn't happen. Have it checked and let us know what you find out.

Well fellas, tonight by chance I figured out my little problem with the creaky roof. Turns out is was the door seals (inner and outer). They were dry and sticky, and all I had to do was condition them with some Adams Super VRT. Good as new and no more noise! So happy I got this resolved!

This is probably what's happening in my car. I hear some noise coming from passenger door or roof.
I will try this out tomorrow and update my interior rattle fix diy post.

Thanks,

Hey guys I have a new F80 M3 with carbon fiber roof. Every time I hit a bump the roof "creaks" and it's super annoying to listen to. Anyone else having this problem? Is there a fix?

Cheers!

Are you sure its not the interior trim? I would doubt it's the roof.

It sounds like it's coming from the roof and the side pillars

It's most likely the seal around the windows. If you take it to the dealer they will lubricate it and it will go away.
This car has a stiff chassis so be prepared to hear more noises along the way.

I have 6k on my F80, its been trouble free beyond the pebbles in the break shield.

MDIVISION does bring up a good point.

Thanks bro I'll have this done at my 1,200 mile service next week. Cheers!

I read about this earlier this year. I think people were solving it by opening the doors and shutting them again if that didn't work have the rubber molding lubricated. I believe the rubber door seals were the culprit.

Does the rattle go away when your windows are cracked open?

Just got them tinted so haven't tried this yet but definitely will! You guys are awesome!

It's a rattler but you just get used to it!

For the door rubber get some Gummi Pflege (rubber care)
Dealers used to sell it, now easily available from Amazon.

You just apply it straight to the rubber with teh bottle applicator.
A little goes a very long way.


Also dont forget to wax the door jams when you wax the car. Helps prevent many of these noises.

Thank you sir, I went ahead and ordered it. I did try rolling down the windows a crack and the "creaking" did go away. Hopefully the gummi pflege will solve it! Thanks guys!

That lubricant will temporary solve the issue and it will come back once it dries up so either you can add that to your detailing routine or have the dealership fix it for good by adding a strip of teflon tape on the pillar where the doors weatherstrip meets the metal. That prevents the weatherstripping from rubbing against the metal causing the rattle.

I had the same issue when I first got my car and the dealer fixed it using the teflon tape and no more rattles at least from that area.

I used the Gummi Pflege and the sounds came back pretty quickly. Recently mine has worsened to the point where they will creak going down the road wheras before it was usually in parking lots turning or going over speed bumps or whatnot.
