I took it once to the dealer, he said its twin turbo noise/spooling and all that.
I have 2500 miles as of now, Even the wind noise is too much in my X5d, After I play the cd/radio...@ 65/70 mph..I hear the wind noise/road noise...its so annoying, I am going to the dealer again next week. Not sure some of this is related to RFT

I agree, engine clatter is more in the cold mornings, I am totally disappointed in this regard.
