Hi
Thanks for your post.
What kind of noise were you experiencing from the back? Can you describe so I can understand if it's the same issue as mine?

It would be great if you write a guide on how you fixed it.

I think I have the same issue, it sounds like the rear shelf is loose.

Whether they used the fix from the link or a standard BMW fix (the problem is well known) it was perfect after that and still does not rattle weeks later.

Take it to BMW folks! They'll fix it.

However they still haven't fixed the problem of my car randomly starting itself like a sentient beast on occasion! No one else seems to have the problem though... so no known cure.
Every so often my remote start fails when I use the connected app. Maybe BMW is getting their wires crossed and I'm starting your car instead! Lol

Is there a guide on what to do about the sunroof? It's gotten really bad. I want to take it to the dealer but I want to make sure they fix it correctly

Got my car back from the dealership and there's as apparently a note from BMW for the sunroof creaking sound, they cleaned the sunroof seal and applied grease on it.

So far so good, I don't hear any noise coming from the sunroof.

when i received my m340i about 2 weeks ago, the passenger speaker would rattle like hell during bass. In the past week, it has completely silenced the rattle even under heavy bass. What could this be? I thought it was a blown speaker based on the e46/e90 speaker situation?!

Passenger was seated when this happened!

I'm hearing a "toc toc toc" from what seems like B Pillar.
I get that noise from both left and right. It seems at head level.
Not related to bad roads, because I generally hear it when driving fast on highway.
Any idea what can it be? Looks to me like something related to the windows or the isolation rubber.

It might be obvious, but check that your passenger seat belt is correctly positioned. Whenever I've had that kind of noise is because the seat belt didn't retract properly and it kept knocking against the B pillar.

Unfortunately it's not that.
This noise happens even when both seat belts are in use.

Do you have any more details about the sunroof note?

I dropped my car off at BMW today... I showed them the noise and they agreed it was very loud. I never drive with the sunroof cover open/glass closed, but we did during the drive with the shop foreman and it was amazing how loud it was for a car with under 4000 miles

I have two distinct noises that are driving me up the wall.

One is a rattling from the glove compartment. I know itís the glove compartment because when I hold it with my hand it stops. Itís near where the handle is to open it.

The other is intermittent creaking coming from the plastic pillar on the drivers door. The part that goes around the window closest to back of the door.

Both very annoying to be honest.

Sorry, I don't have any details about the sunroof note. How does your noise sound like?
Mine was like some plastic piece was loose in the sunroof area (sunroof closed). I could hear some cracking sound when it was tilted.
But no noise whatsoever when the sunroof was fully opened.
