  1. Thank you Reachme, that is an excellent suggestion. I'll check that out immediately and report back.
  2. 2004 Cayenne Turbo- I could use some help figuring out the source of a leak and how it managed to kill both the radio head unit and the sub. A week ago the PCM 2 head unit stopped working. Black screen and no sound output. Checked all the fuses and all were good. Upon closer inspection I noticed the screen on the head unit and buttons would glow slightly when the power button was pressed. A few days later I happened to be under the loading truck floor because I needed the tool to remove a headlight. That's when I noticed the water. It looks like there was about 2-3 inches
  3. Hello, all. 2004 CTT. I am having a weird power steering issue. Twice when going over a speed bump or up the curb of my driveway the power steering seems to quit. Steering becomes very heavy like all assist is gone. The problem goes away after a restart and seem directly related to hitting a bump and there being suspension travel. The PS fluid is topped off and there are no leaks. The last time it happened the car also threw a P0441 code. After reset with the Durametric is hasn't come back. I can't figure out how these issues are related or what's going on with the steering. Any help
  4. Thanks very much for the information. It's very helpful. If you have the ability to locate your notes with the regard to the coding option, that would be very much appreciated.
  5. I am attempting to lower my Cayenne a bit using the Durametric Tool and Software. It works as it's supposed to work but I am not sure if the original height values are correct or if the suspension height was modified buy the previous owner. The original values for the front wheels were read at "190" and for the rear at "237" using the Durametric software. Does anyone know if these values are the original correct "Normal" height values and if so, what is the maximum permissible lowering value? I have tried a few settings lower than these numbers, such as "180" for the front and "227" for t
  6. 2004 Cayenne Turbo Guys, I could use some advice. Cayenne has begun to leak fuel from the driver's side somewhere near the top of the tank. I can see small amounts of fuel running down the seams in the tank and you can smell fuel outside the car, but not inside. I can sometimes see a few drops on the ground after it's been parked. Related to this, I have a primary fuel pump failure, but these did not occur at the same time. The pump failed weeks ago so I pulled the fuse and have been using the secondary pump until I can get a clear window in my schedule to replace the pump. So now I am
  7. The truck just passed 90,000 miles. Seems like the drive shaft and the fuel pump picked the same week to expire.
  8. Thanks to a little more research on this forum and the great tip of removing the fuel pump fuses one at a time, I was able to isolate the problem to the primary fuel pump. It's running fine now on the secondary pump. Does anyone know if it is okay to run on this pump for a while? I'm not going to be able to get to the fuel pump replacement for at least a week. Wvicary, thanks for you comments. I assume right and left refer to exactly that as you view the pumps from the rear of the car. In the diagram online it sort of seems like the pump are fore and aft under the seat. Can you just conf
  9. Let my son take the Cayenne to prom while I was out of town. Of course, it chose that moment to have a major issue. Engine started running very rough. Died several times. We had the car towed home. Now it starts up fine, but idles very rough and will die after a minute. If you try to rev the engine in neutral it will make about 3K RPM before sputtering a bit and quitting. I could really use some idea of what this is before I take it to my mechanic. Strangely, It was just in the shop two days before this incident having the rear drive shaft replaced. Could any of this be related? The c
  10. Thanks Loren, it appears that I have the amplifier and park assist module. I have no CD player. Apparently nothing is missing from these compartments. That's good to know :wrench:
  11. I am a new owner of a 2004 Cayenne Turbo. Can someone please tell me what is supposed to be in the 2 small storage compartments in the luggage area? On mine, there is nothing in the driver's side compartment. It's just an open space with some kind of Bosch control box at the bottom. On the passenger side there is some other sort of electronic box with and the air compressor line stored up against an empty velcro strap attachment point. It looks like there is a holder for something else in there, but whatever it is seems to be missing. Any help would be appreciated. Thanks
  12. If it's anything like my '04 Cayenne Turbo it is very simple. Get the install kit from Valentine which consists of an inline fuse holder and a small black module to plug the phone cord in to at the fusebox. My fusebox is on the driver's side under a panel right on the left side of the dash when you open the door. Just pick a fuse (I used the one that powers the 12V cigarette lighters) and tie in the red wire there. The easiest way to do it is to just wrap the wire around the blade of the fuse and shove the fuse back in place. Just make sure the wires don't hang out and come in to contact
