Hi all, I'm new here. I just received our v6 past weekend 4 months after putting the order. I noticed that there is whistling noise when the blower set on level 1,2 and disappear on the higher fan speed. Does anybody has this issue?

Thank you

 

I also hear a second fan that blows in the back of my V6 Hibryd. It runs on its own even when I turn the AC down.

 

Never noticed this whistling(will look out for it from now on)
Though to me,the AC is the only part of the Cayenne that feels underpowered
Why can't Porsche borrow one from VW??It is anemic compared to the one I have on my 2001 Audi A6...
Good luck,keep us posted

 

The 4zone is so much better than the standard, as with my old GTS.
Extra blower and vent in back makes for cooler air faster IMHO

 

I believe you..did not get the 4z,cause I thought it would be redundant
Same mistake I made in not getting the thermal/noise insulated glass...
