Jet or turbine sound as you decel/downshift towards a stop light

What is that jet or turbine sound as you decel/downshift towards a stop light or full stop? I had the same sound on my 09 M3 DCT.

That sound was non existent on the crappy 11 550i. So we know its not the turbos.

I am thinking its the DCT tranny. Thoughts?

Love that sound BTW.
