Sounds like the exact same problem I'm currently working on correcting. I'll be dropping the headliner this weekend (the Vegas line is 12 plastic trim clips broken....anyone want the over/under?) to diagnose and fix the problem. From doing a ton of research, it sounds like the primary suspect is a sunroof drain fitting that sits just behind the sunroof (non-panorama roof).....they start leaking where the plastic fitting meets the drain tube and it has to have silicone sealant or similar applied to stop the leak.
Culprit number two could be a leak from underneath the rear "spoiler" trim panel, but I'd say that's a lot more unlikely than the suspect mentioned above.
I'll keep you in the loop if I get to it this weekend. I had to trash the bose box as it was trashed after being submerged, so I have this repair on my "FIX ASAP" list.

If you open the rear main hatch and remove the covers from the hinges, you will notice two small drainage holes. These get clogged with debris. Unclog them with a piece of wire as this may be your problem. Had the same issue, BOSE amplifier for subwoofer got trashed, never to work again. Since I unblocked these two drainage holes, I haven't had any water filling the spare wheel area.

I have this issue and have a full warranty on my 2006 CTT. But, the dealer is a real *** about trying to "lawyer" their way out of doing anything, and now claim the warranty does not cover it. Here are a couple of her quotes:
1st-"The warranty company will not cover it. Since there's no parts that have technically failed on the vehicle yet its considered an adjustment. I tried the angle that it will cause other issues down the road but I didn't get any help. The negative is that If it does, it still probably won't be covered because of an outside influence. Its not an internal mechanical failure."
2nd-"No. It's the packing around the seal, not the seal itself. There's no part number for this because it's an adjustment. Therefore, they have nothing they can technically cover. You are more than welcome to call them as well."
Anyway, it is obviously covered by Fidelity Platinum but for the life of me cant figure out this chicks hangup. Maybe, a snapshot of the service paper stating warranty and what was put in would be real helpful.
If you can think of a way to 'splain dis to her in a language that she can easily understand I'd be greatful.

Sorry RushDL but my repair was covered by my OEM warranty, not an after market warranty. FWIW my spare wheel well was completely full and the Bose subwoofer was totally immersed in water. This is a known, well documented, and potentially expensive problem. I wish I could be more helpful.

I wonder if they actually teach these mechanics how to diagnose problems with our Cayennes. I just pick up 2008 CS from the Stealership and after 2 weeks, they couldn't find the water issue on the passenger side or the leaking going into the spare tire well. I'm finding these things from you all. What am I paying them for?

My history with water leaks has been as follows:
1- First it was a mess everywhere, so I started by taking off the roof rack channels, siliconed the screws and holes and thought I was done, but couple weeks of rain later and it leaked again.
2- I decided to open the sunroof and pour water into each of the 4 drain holes individually, and watched it all leak inside, so I lowered the headliner and siliconed those drain tubes to their ball joints and again thought I was done, but few weeks later and it leaked.
3- Finally, I laser cut a piece of car wrap vinyl to a larger offset of the sunroof, and I covered the entire sunroof hatch! Voila, No more water leaks and it was all dry EXCEPT for the D pillar, the rear right side of the car. This is why I have no other suspect but the spoiler trim panel.
So if anyone has any details about how to fix water leakage from the rear spoiler, please share.
