GoodAfternoon everyone, I tend to have slight OCD tendencies and I just can't get over nor understand the origin of this very slight buzz whenever I depress the accelerator which is only audible with the music off and all windows closed.
The sound is similar to a 90's era PC's loading sound, which is the best way I can describe it. Constant for as long as the pedal is depressed.

Has anyone here experienced this as well?

So far I have narrowed it down to possible the module which sends engine sounds inside the cabin or possibly throttle actuators? BMW of Brooklyn states that this sound isn't out of the ordinary. Any help would really be appreciated.
Thanks
Pat
