I can't tell you how much I really appreciate you and this forum right now. I told my SA about this and now that buzzing is gone. I never really knew what my car sounded like cuz of that stupid buzzing. And i drive and cruise around town at 2-3k rpm. Man im in love all over again.

Here's what was installed and another pic for attention 😎

If I get the buzzing sound between around 2k and 3k RPM, both with and without A/C, anyone know the solution?

Really? Why?
I hate SAs in Boston and he didn't want to put the exact TSB number in his system, and he claimed that he would let someone reproduced the rattlings at 2500RPM. But luckily bmw technicians are all very good and issued the TBS for me automatically

2017 F80 M3 owner here. Please see the 2 videos below. Is this the noise that everyone is/was hearing before the fix? Audible under load in 2nd, 3d, and 4th gear between 2-3000 rpm.

Nope, the 335 noise was a harmonic buzzing sound.

I'd be interested in what your dealership finds. I have the same rattling sound in my 335i around 2,500rpm under load.
