I had a same annoying problem. The noise came from the "B" pillar. The noise became stronger if I'm driven over 130 km/h. The noise sounds like a strong wind noise. The problem was the cover under the car chassie. If you see under the car you can see it is covered with a black panels. This paneles attached to the chassie with special clips. This clips usually are not locking the panels tight enough. In this case the panels are moving during the car is runing due to the airflow under the car. When the panels are moving You can hear this strange noise from the "B" pillar. The solution is, remove the clips remove the panels, make the clips more tight to put hard rubber or hard foam under the clips with glue. And put everything is back. Check the panels after the reinstallation. If they are not moving, tight enough, the noise will disapper. I hope I could help You.
