e65, straight 6 730i has the strangest whistling / howling noise. Especially at low speeds. I have no clue where to start and I am unable to pinpoint the origin..

turned out to be a loose a/c belt. Pulley on the a/c compressor went and in turn damaged the compressor. just took off the belt (no a/c for the moment) as I wait for a new compressor to be shipped in for DIY installation.
