40e subtle buzzing sound every time I brake
I recently purchased a CPO ‘16 40e. Really love it so far! I’m just noticing a faint buzzing sound when in all electric mode when I come to a complete stop. It sounds like a cell phone in silent mode. It’s consistent happening every time. Is this just a quirk of the hybrid system? Only thing I found online was from a 530e owner who reported the same thing. Someone in that thread replied saying it was a product of the regenerative braking. Thanks in advance for any replies.

Just my hunch. Somebody on here knows and can give you the real answer if I'm wrong.
