Hi!
I recently bought a Z4 3,0 2003. I have noticed that when the ac button is on there is a slight knocking sound from the fan in the driver´s compartment. When i turn the ac off the sound immediately stops. My first thought was that the sound may come from the Ac compressor. But when i open the bonnet and listen over the compressor I can´t hear any knocking sound at all. So perhaps there is something that is loose and vibrates when the compressor is running? I would be thankful for som help on this... I have also recorded the sound near the fans in the drivers compartment http://dl.dropbox.com/u/4297038/missljud.m4a
Regards,
