If anyone has any solutions I’m glad to try them.
This fixes it for good, I can vouch for this personally:

another thing that never worked on my car is the scroll wheel for the radio (on steering wheel). it intermittently stops scrolling through selections even while im moving the wheel. oddly enough, it also stopped working 100% of the time when i push it in to "select" an option....but ONLY on SAT radio. on FM, AM CARPLAY, etc the push function works 100% of the time. its bizarre almost like its a software issue.

my car was a 4/2019 build date. with the late july software version (cant remember the number).

the one thing that works perfectly is apple carplay which was the thing that i thought might be an issue LOL.
Have the same rattle problem. Went to dealer twice and it always came back just one day after dealer had claimed they fix it.

It seems like it goes away when I adjust my sunroof... I'm wondering if that is the real problem.

Then your issue is with the sunroof, the trunk rattle is a separate issue. Lots of known rattles with this car unfortunately

Noise from the frame of the display

Hi guys, I'm Gianluca and I'm Italian. I own a 320d and this is my third BMW. The car is wonderful but can hear a lot of noise from the console. Particularly I can hear noise from the frame of the main display but when I push with the finger in the corner, the noise stop; you can check it from the link of video. Is there someone else who have the same problem? It's really annoying even because the car is very silent. Anyway In the next days I'll bring the car to the dealer

There is an issue with the sunroof: when you open your it completely, you will see that the plastic components that line the hole and that e.g. Divert any incoming water have slight gaps between them.

On cold days, that plastic gets a bit less flexible, producing squeaks. I fixed it by shoving a tiny bit of felt in each of the gaps. Problem gone...

Could you take a picture of the area where you put the felt?

Sorry for the late of my answer. As you can see, it's the corner on the right. When I push there, the noise disappears

I had a similar rattle, the fix was easy. Just wedged a few small pieces of felt tape between the plastic covering the screen and the enclosure. You can't see them if you push them in.

It seems the plastic was a bit loose in my car.

Problem fixed

Still seeing people with the centre speaker cover problem. I absolutely hated it both when listening to music and accelerating. I emailed the link to the fix posted in this thread (thanks whoever that was!!) to my service rep. Then I took the car to the dealership. 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.

Didn't expect a new Bimmer to sound like my old school bus.
Guys, I have the same noise on G20 330e. It sounds like someone in the trunk is playing with a parker pen. Happens all the time and more over bumps and potholes. Drivers me nuts.
Is it the same noise you hear?

The car spent 2 weeks at the bmw service center and is going back next week. They have no idea what it is...

Hi
I have a late Oct 19, 330e and have been plagued with a clicking sound that intermittently sounds from the boot area. Just like the last post, it sounds like someone clicking a ballpoint pen in & out
Was in dealer for repair over 3 weeks in Dec 19 and they said it was spot weld on rear parcel shelf so added new weld, went through paint shop and had new back screen fitted - when they road tested it, sound was still there although quieter, in a new place and more frequent. They kept working on it and later tried the shock absorbers by swapping them over left to right - the sound swapped sides so a new one was fitted. The car tested OK so i collected it.
It drove OK for about 200 miles but then came back....
Went back to the dealers and they had it for 5 days - they used an endoscope to provide BMW with images of inaccessible areas around the shock absorber mounts then later injected wax into the area.
I got car back and sound returned again - exactly same sound but now on opposite side of car.
Drove to dealer on spec and tech guy drove around with me. He acknowledged the sound and re-seated the shock absorber support bearing plate to see if it changes the sound until i return on a booked appointment
Car going in again on 6th Feb

The dealership are being great however im loosing faith that the issue will be resolved

Has anyone gone through this and had it cleared?

This sounds bad man.
I thought this is fixable but what you're describing is not encouraging. What a nightmare. This is my first bmw and it is absolutely not what I expected

Just so wired that M340i and 330i has the same interiors, but one is a crack box one is dead quiet. I'm thinking maybe my 340 is the first production car( April), and the 330i built in September???
Hey jeremycanada any news from the dealership ? I think I have the same issue.

I can hear a creaking sound coming from my sunroof when it's closed. When I open the sunroof completely the sound seems to go away.

Hi, they fixed it by cutting open the rubber and stuffed something in there( show in the picture) and the ordered a new rubber seal to replace the one on my car. Now the sunroof is dead quiet.

Could you describe what you did a bit more? How did you remove the parcel shelf? What plastic piece do you mean?

The plastic vent against the rear window. There’s a bunch of things needed to be taken off to get the rear deck out but once it’s out once it’s easy to do it again.
