It is mostly noticeable windows down from expecially from 0 to 30mph ish (after that the tyre and wind noise is higher ) .
During my planned service 5 months ago i did mention it at the bmw dealership about that noise and i showed the mechanic what you can see and hear in the video and he said to me that everything is normal it is just the air rushing in the air intake.
Now I am asking to the 330d/430d owners, is it normal, should i bring it to a non bmw garage and have it looked further?
Thanks

Hey mate
Did you ever get to the bottom of this sound? I have just picked up a 2015 430D and I think it makes this noise between 1500 and 2500rpm approx. Not under full load, just when feathering the accelerator.
Its booked in to BMW Wednesday to have a look under warranty.
It almost sounds like a dump valve/boost leak. But when hard accelerating when the turbo is making full boost there is no noise, which would be counter intuitive if it was a boost leak, in my eyes anyway.
Cheers
