Its coming out from the center air con vent. Turned of the air con, the noise goes away. Had the blower changed, but the whizzing noise still come back.
Read a BMW UK forum from a 530 owner, he narrowed the problem to a faulty auxilliary water pump.
Anyone can give some advise. Worst case would be to head to PML to have it resolved.
Thanks!
