Chino, This is extremely easy if you don't make the same mistake I did. I assume you are trying to get to the battery??? Anyway, there are four bolts that hold the seat to the frame. You do NOT need to touch those four bolts to rotate the seat back. Those four bolts are black. There are two silver bolts under the carpet tabs at the front bottom of the seat box looking thing. Right at the rear of where your floor mat ends. You will need to pry up the carpet tabs, they are precut to allow you perfect access. Both are triple square M10 bolts. Cheap tools at any DIY auto parts store that fit into a 1/2" socket. Once you remove those two bolts you can rotate the seat towards the rear. I took lots of pics yesterday. Whole thing should take you about 30 minutes. If you need to really get the whole seat out, the four bolts I mentioned previously are easy to get to by moving the seat fore and aft. There are plastic covers over each bolt at the front and rear of each seat track. They fit pretty well, but if you stick your head real close you will able to see the mold line where they separate. I did not even need a screwdriver to pop them off... just a fingernail and upward pressure. As I said, I will try to post some pics later if you have not figured it out already. Jason 2004 Cayenne S

I just had to have my driveshaft replaced this week at 67,000 miles. Also the left front control arm... as the main bushing failed. Supposedly both are extremely common. Jason 2004 Cayenne S

Porsche just changed my whole instrument cluster under extended warranty because the display was "flickering". Not a bad as yours! But, after they were done I talked to the technician and he told me that cracked pencil coils can cause all sorts of weird problems in the display area as well as other instrument cluster issues. He also changed all eight of those. The good news for a DIY is that changing the coils is easy and relatively cheap. The updated part number sells for around $20 each... you need eight of them.

I installed my Fabspeed pipes Friday night. Got them in after about three hours. All the hardware and gaskets came in the kit. Perfect fit. Way to go Fabspeed!

I have fabspeed pipes on order but tonight I decided to remove the exhaust clamps between the 2nd cat and the muffler. Sounds awesome at idle but a little too nasty going down the road. Am thinking that after the bypass pipes maybe some straight through resonators might be all that is needed for a nice aggressive sound. I really can't stand the wimpy minivan-esque exhaust. Without the rear muffler you can almost hear the Porsche in the motor... there has got to be a sane way to unleash the beast.

Was there any sound difference just doing the bypass pipes? I used to have a 540i six speed that had a NASCAR sound before the Cayenne... I really need some noise!!! Any recommendations?

I got lost today in South Florida cause they built a new road since 2004. Dang it... there has got to be an update for something that is only four years old!!! Anyone having any luck at all??? Thanks JB 2004 Cayenne S

I just did this over the weekend on a black 2004 Cayenne S. Wow, what a difference!!! I really love the new look. I also have to give props to www.bumperplugs.com I ordered the markers on Wed, he emailed me immediately asking what generation the truck was and the parts showed up on Friday. Actual Porsche parts all packaged up and perfect. (I am in no way affiliated with them other then giving them money and in return being a very happy customer) The install was difficult until I bit the bullet and just unscrewed all the fasteners and pulled out the inner liner. After that it was a breeze. I would offer that unfastening all the screws is a really good idea. My wife has an ML430 that I tried to wrestle with the liners on and ended up actually bending some sheet metal so the extra few minutes it takes to do it right could save a huge headache by not subjecting yourself to bending the precious Porsche fenders :)

Can't you simply scroll through the dash display on the wiper stalk and see if pressures come up? Or look under settings to see if it has been disabled? That would be the easiest way... other then seeing if it has metal valve stems :)

So I received my Durametric software in the mail and got it installed and hooked up to my truck. Very cool stuff... a little less info than I wished for, but way better then the wooden ouija board I was using previously. I started with a simple test to see how well those odd looking intake tubes really work. With all the trouble that mass flow sensors have I was flabergasted to see that Porsche now has two of them!!! On top of that, they only feed a single throttle body. I figured that with two they would at least feed separate banks of the motor, but aghast... I found out that the truth is only one throttle body for all 4.5 liters. Anyway, once I saw that I could monitor the output voltages of the sensors independently I was immediately excited (yes, I said excited... you might be a car nerd if you get excited about that one). So the very first data logging test I ran was to monitor those two outputs as well as engine speed (I did throw in misfires for good measure but not one hit so that is a moot point). As the logging progressed, I varied engine speeds and how quickly I snapped the throttle open and closed. (I also learned that the Cayenne limits revs to around 4K when in Park). My hypothesis was that one side or the other would be the favored side for sucking in air... whether due to less clogged filter or better postioning of the intake snorkle or whatever, I figured one side would flow more and the computer woudl simply add the two values to measure the total air flowing through the single throttle body. Well, my hypothesis proved incorrect (I believe the technical term is that it was "rejected"). Both mass flow sensors were pretty much dead nuts on top of one another. There were four sampling points where they varied... yup, two were higher on the left and then two were higher on the right. Did not seem to matter whether it was opening or closing the throttle. **** it... they were both sucking equal amounts of air. I figured there would be an easy upgrade to increase the flows so that they matched. Anyway, it appears that the technical team at Porsche did an awesome job... can't believe I doubted them :) So what does this all mean? Well if you made it this far in the post, it means you are a car nerd too. But what it really means is that sometime this week, I will remove one of the air filters and do some more data logging to see just how much restriction is introduced by the aircraft carrier sized paper elements that are lurking under our hoods. Good luck and good night. If anyone has any additional info that might help me in my quest for cheap efficiency improvements... please point the way! In the spirit of true research, I am open to any and all viable suggestions. Thanks Jason 2004 Cayenne S

I did try to erase the code... and it promptly returned. The Batt V ran at a constant 13.5V in the data logging mode regardless of engine speed. I did notice a few flickers of the pixels yesterday when the low fuel indicator was on... very slight but they would kind of dim a few pixels then come back strong. Nowhere near as bad as my old BMW that woudl just go out :( I will keep digging into the stuff you sent and see if I can isolate the fault and report back to the group. Thanks for the help!!! Jason 2004 Cayenne S

So I just fired up my brand new DUrametrics software... everything looks great except for one fault code I am getting under the "Electrical System". P0907 Load Management. I searched the site and can't seem to find anything. Anyone got any ideas on what this means??? Thanks in advance!!! Jason 2004 Cayenne S

Hi Folks, New member (and new owner of a '04 Cayenne S) here... been through all the posts though, awesome site!!! My question is whether or not anyone has found a good and inexpensive source for a Cayenne workshop manual? I like to do most of the work on my cars myself so I usually buy a Bentley or equivalent, but there seems to be nothing out there for a Cayenne. I know that this is not a truck that most owners would work on themselves, but for an enthusiast that has a sick streak like me that wants to do the work himself, where is the best source. I have read 75% of the TSBs on this site and most of them refer to a workshop manual procedure so just trying to find that next level of detail. I found one place online that I have never bought from before that will send you a CD for about $125 but was wondering if anyone has any other reliable sources??? Oh yeah, I also picked up a copy of the durametric software and cable after reading through this site... can't wait to plug into my beast this weekend. And my clear side markers are in the mail after reading how cool they look on a black truck. Thanks in advance!!! Jason B Viera, FL 2004 Cayenne S 1999 ML430 1985 930S 1983 944
