435i Xdrive Low Whine on Decel

Hi Everyone,

I noticed lately that my car makes a low whine noise as the car decelerates, and follows the transmission downshifting, BUT only when the AC is on from what I have noticed. Any thoughts? Car has 39k miles on it.

I find it hard to believe that no one has experienced this.
