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.
If its more noticeable when slowing quickly its probably the front brakes 'whirring' as you slow down to a stop. Fairly typical with a two piece rotor design.
