The problem still continues.

Not the shock absorber sound.
It's not a door seal.
It is not a filter cover.
Not a torpedo cover either.

Today I discovered something new. With the steering wheel facing left, the sound is cut off even if the road is rough.

Also, the days I wash my car, the sound does not come for 6-7 hours.

Well, I just had a hydrobearing (#7) replaced along with the regular service lately. There had been no sound/symptom but they dug it so meticulously looking to suck extra money it was painful to watch. They (an official BMW service) told me it wasn't necessary to replace the other one (apparently upcoming) as well and do the wheel angles correction.

Hi

exact same sound on my M135i coming from the bottom right over bumpy roads, like styrofoam rub. I changed the engine mounts and retighten the subframe, and it went away for a while ! for 1 month absolutely quiet ! May be caused by engine rocking. Have that checked. I eliminated suspension because it could happen stationary on the brakes but with slight throttle. My mechanic pried the engine while on a hoist with a bar and it creaked abit. Good luck and pls report back ! Lately its coming back again .. SIGH!

Does your car have the teflon tape fitted along the top where the door seals touch the body? That solved the issue for me.

Did you check the foam added to each door (right where the side mirrors are attached) maybe? I had a similar squeak noise coming (albeit when closing/opening the door) in that area. Might be worth taking a look there.

Hi everyone,

My problem is still not resolved. I went to many BMW Services but they could not find the source of the problem.

The sound stops in rainy weather and when I just wash my vehicle. It comes back in dry weather. What could be something that cuts off when it gets wet?

Wait for the noise to occur again (and for it to be dry outside) then lean under your car at the front right and spray a large quantity of WD40 (or any other lubricant) on the 4 points of attach the parts in the diagram circled below, and go for a walk to check.

You're welcome !
You should ONLY put it (WD40) on the attachment or anchor points of the drawing.
This will make it possible to eliminate some causes (temporarily)
To do this correctly, you will need to lie down, passing under the front passenger door to access it.
See you soon

Do parts need to be changed for a permanent solution?

You have to wait for the state (of the video noise) to pronounce this

As mere water kills the sound you should be able to use it to isolate the sound source just as well.
