Sorry guys, I can't let this go. Gotta get to the botom of it. I only have 500 miles on my CTT and have had many problems with it. Most have been fixed except for a few. My biggest complaint is this clicking noise while driving. They are telling me it's the PDCC and is functioning normally. The noise sounds like the sound of an A/C compressor clicking on and off due to a bad relay or something. They said all they're Cayennes w/ PDCC sound like that. Anyone here notice this from theirs with PDCC? I find it hard to believe Porsche would let the PDCC make that kind of noise. It is so bad I'm thinking of getting rid of the truck. It sounds horrible Other problems were heat shield vibrating against the floor and the power steering has failed twice

 

i don't hear what your hearing on your truck, next time you are up by me you can drive mine and compair

 

sporters78- Do you have PDCC??

Oh and the heat shields are rattling again. A few more times and here I come lemon law

 

but of course i do, you might have a leak in the pdcc system

 

none of the magazine reviews with PDCC cars made any mention of such a noise. think about it: if it was there, the car mags would have jumped all over it.

i ordered PDCC on my Cayenne and have not been told, nor do i expect to hear such noise.

go to another dealer with a PDCC and test drive?
