I am new to my 3. It seems to me the first day the car didn't have a whine. Now I get a noticeable whine when lifting off of accel., it also whines on acceleration. It is as if the rear differential (on a ICE car) was going out.
I suppose it is the speed controller. but not sure if the noise is an indication of something being wrong.
