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 of water at the bottom of the wheel well. I removed the sub and discovered that the amp and associated wiring had been submerged. There is not rust anywhere so I am thinking this was recent. I am assuming this is what killed the head unit....but is it? I need to discover the source of the water (it has rained here quite a bit) and decide on the best course of action. Replace head unit and sub with new aftermarket or buy used and put it back together with OEM parts. As I side note, my windshield washer pump also died about the same time. Anyone have an opinion on the source of the water and whether to go aftermarket or OEM on the replacement radio? Thanks
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 or insight would be appreciated. Thanks
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.
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 the rear and I get an error saying that these values are "Not Permissible" Any help identifying the normal and permissible Durametric values would be appreciated. Thanks 2004 Cayenne Turbo
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 wondering if this leak is related to the pump failure or if I am looking at two different problems. Any advice would be appreciated before I start disassembling things. Thanks
The truck just passed 90,000 miles. Seems like the drive shaft and the fuel pump picked the same week to expire.
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 confirm that the primary is the left pump (Driver's side) under the rear seat? Thanks for the help and thank goodness for this forum.
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 car threw two codes which are gone now P2177 and P2179. Both related to "lean of peak at idle". There are no other warning lights or codes displayed. Thanks for any help the members can provide. 04 Cayenne Turbo
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:

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
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 with something else. Nest you have to tie in the ground (black wire) at the fuse box. The entire metal structure around the fusebox is grounded, so you can either remove one of the screws in that structure and place the grounding U shaped connector under in, then tighten back down, or you can drill a small hole in it and put your own metal screw in with the U connector under it. Stuff the excess cable in to the area around the fuse box. There is plenty of room. For me it was then very simple to run the black phone cord up the corner of the dash, to the edge of the left A pillar trim and then using a small screw driver to push on it, stuff it inside the A pillar trim between the pillar and the windshield all the way to the top. Then just run it under the edge of the headliner against the windshield and up to the rear view mirror. On my '04 it stays in there just fine without anything to hold it in . You may want to reverse this procedure and start running the wire from the rear view mirror if you are unsure about how much length you need. I use a suction cup mount to hold the VI in place just above the rear view mirror. Just plug in the unit and it should power up. The whole thing took me about 20 minutes, but I've done it a few times on different cars so I am familiar with the idea. Good luck.
