Are you referring to the whistling sound when the fan is turned up high? I get this sound when the windows and doors are all closed and the fan is on high. Check if this happens with the car stopped. The dealer couldn't figure out why this is happening and how to fix it. I'm going in again for my 20k service and I'll ask if they figured it out. It seems to be a common issue in the Cayennes on the lot.

If this is your problem, try opening the window a little or the sunroof. that seems to relieve the air pressure and stop the noise.

There should be a new TSB for the whistling sound at your dealer by now. It has to with little holes on the front door frames that need to be sealed up. Should be covered under warranty.
