Sorry abut that -- misread your first post. Hmmm, not sure. Info on how to pull the plate around the shifter is here in Renntech. You could do that and see if evidence of a spill is there and stat ruling out issues. I tend to use my stick for shifting more than the steering wheel controllers -- like on curvey mountain roads so I totally understand why you want to resolve this.

I had a similar problem on the right steering-wheel tip controller -- the entire piece of the center steering wheel was replaced -- which includes both tip switches. It was gummed-up from a spill from the prior owner, purely a mechanical issue. It was a thick gooey liquid that congealed. Like a chocolate syrup. It was a CPO repair -- luckily the dealer noted it as an issue to be fixed when they converted the vehicle to a CPO. We happened to purchase the vehicle before they had time to do all the work. In hindsight, I should have asked for the old part -- they may not have offered because it contains an airbag which is basically an explosive and they might not have wanted the liability of giving it to me. From what I recall no specif tip controller part # exists -- you need to replace the entire steering wheel center -- airbag and all. Let me know if you need that part number and I can look it up. If it's expensice it may not be worh the cost to repair -- if you don't use the wheel-mounted tip controllers a lot perhaps it won't bug you too much to leave it the way it is.

Agree w/eVoMotion -- total scam. Don't waste any more time on it.

I have a 2004 Cayenne S. Last summer (in North America) after a long freeway drive in very hot sunny (no rain for months) weather the carpet between the driver's seat and door was wet -- soaking wet. And parked in the garage water pooled on the garage floor under the passenger side but not the driver's. Water discharging from the AC drains onto the ground is normal. Took to dealer (CPO) and they said they'd clear-out the vents/drainage. The problem did not return -- I also complained about a super funky mold smell even though I had changed the charcoal interior air filter that summer. (Found the instructions here on Renntech -- super easy.) The dealer said they'd clear it out and add some antiseptic. They did and the smell is better but when switch off/on it's surfaces from time to time. Now, a year later, hot weather, my wife was driving with sandles on (no socks) and she felt a water dripping on her right foot. I checked it out and found a water-spot under the brake pedal. Not saturated but wet for sure. So, I will now go back to the dealer next week (still under CPO) and ask them to look it over, again. Will post an update. We park in a garage so leaves, etc, do not collect on the windshield so I'm not sure what keeps gumming-up the system. I suppose it could be mold which is kind-of disgusting.

Very, very cool. Can't wait to see the pics. Impressive project 3ball.

I recall somewhere in this forum Loren posted an official Porsche image of where devices can be placed on Cayenne windshields -- many Porsche windshields have thermal layering which do in fact interfere with GPS (or radar detectors, etc) ability to pick up a signal. The locations you specify would not work -- but the best bet is to try it and see what your results are. My handheld GPS device can pick-up a GPS signal from the floor of the backseat -- some devices are better than others. Not the best solution but one I've seen: GPS antenna under the sunroof glass -- but sunroof glass may also be thermal and you have to deal with wires. Up around the rear view mirror is usually clear -- search for that post and picture and you'll be set, Also, review your option codes and determine if you have all around thermal glass.

What a drag. The same thing happened to me with a child car seat in the center back seat. The center belt was in the ratchet mode and i could not pull the belt back or access the release button because the child seat blocked it. So, I cut and destroyed the car seat to free the belt. I figured a new car seat was cheaper than a new belt. In you case you have no car seat to sacrifice. A call to the dealer may help. They'll tell you the bolt specifics -- size, type and torque settings. Your idea is sound -- loosen the belt by pulling the anchors. Just be sure you hold the belt down (or up) as you loosen the bolts or the belt may just pull back more repeating your problem. Good luck!

Like Mudman said, it's your drive shaft. And he's now had three shafts -- his original and two replacements. It's a chronic weak point on Cayennes. I had mine replaced around 60k miles. So now I'm on my second. Ideally I'll get anotehr 60k miles from the new one. Mine was repalced by dealer under a CPO warramnty so I have no costs to cite. You can find a lot more info on draft shaft issue in this forum. Once repaired you'll be back on the road. '04 Cayenne S

Hi Q8: Be sure to read all the posts here on Renntech and you'll be able to start compiling some background data to help form your decision. So much of the vehicle choice is up to you and is subjective -- V8 normally aspirated vs. V8 Turbo (twin) is based on criteria covering performance, cost-of-ownership, how you plan to use the vehicle (tow, off road, etc.) For gear (options) Porsche offers so many packages and individual option selections it's difficult to map one model classification to the next -- for example a Cayenne S may have everything a Cayenne Turbo has other than the Turbos. And see the posts about the Turbo S not offering auto headlights in the base package which is why you'll want to know all the option codes on specific vehicles you are considering before you purchase. For chipping and tuning you can do a lot with most Cayennes (but the return may not be worth the risks). As many people will tell you, Porsche spends millions to make sure their vehicles perform within solid and proven parameters -- aftermarket items may skew the delicate balance and harm your vehicle. Performance tires and other items are not as big a deal. The build-year is also subjective. A low-mileage Certified Pre-Owned (CPO) '04 may be better deal than a non-CPO '06 because if your drive shaft or coolant tubes break you'll be covered. Anyway, be sure to read all the posts here on Renntech and you'll have a much better idea of what to purchase based on your needs and let us know what you decide on!

Hi -- for mirrors moving in unison check your manual -- it's most likely a setting you need to change. (Attached is from a 2004 Cayenne S owner's manual and covers mirror synch.) And be sure you are using the same key -- unique memory settings can be associated to a specific key. For the other issues it may be time for a main battery replacement -- strange issues such as memory settings not being stored, etc, often surface when a main battery begins to fail. Not sure what year or model your Cayenne is so I'm not sure how old your battery is and if you've replaced it recently. Edit: add image.

To only use your OEM materials (PCM, et al) you'll need to tear-up a lot of your Cayenne to make it work and it will cost a fortune. The best and fastest way is to add a device to your Cayenne (or any vehicle). One example is people purchase and hide an iPhone in their vehicle and they track the iPhone via the Apple online tracking tool. It's easy to hide an iPhone and power it -- fuse to low-yield USB. Attached is an example of what the tracking looks like -- my iPhone is not hidden, it's just always in the vehicle, but I can place it under a rug. And if I wanted to hide it in the Cayenne I easily could, I pulled the bottom of the dash above the passenger foot well and there is space, power and reception. You'll be leveraging the cell signal which in the iPhone's case also ties to GPS. You can track the iPhone from any web browser. The attached screen shot is taken from my browser at work. It's pretty cool, you can see the iPhone (if it's in a vehicle) move around. An you can track up to ten iPhones at the same time. If you know how to handle .xml feeds you can build reporting and alerting based on rules you create for where the iPhone goes, time of day, etc. The iPhone solution is the cheapest and easiest method -- other proprietary devices exist but they are pricey. Search Google for fleet management and tracking devices. Or, for basic monitoring (audio) this is excellent: http://www.dealextre...ls.dx/sku.19634 I use one with a pre-paid SIM and it is very, very cool. You basically call your pre-paid SIM number, the device silently answers and you listen to whatever is going on around the device. In fact I bought one for a one-use project knowing that I'd never be able to retrieve it. Just be sure to purchase your SIM cards with cash. The usual disclaimer exits for all these tips -- follow your local laws, etc.

Hi -- give the folks at Sunset Imports a call or send them an email -- they may know if it's possible and if so can sell you the parts. (Renntech members get a deal.) Hope you can upgrade without too much complexity. Let us know what happens. Phone: 1-800-346-0182 Email: porscheatcost@sunsetimports.com

I ran a few searches and no real answer. A dealer may be the best place to ask. As long as the memory settings are stored in the seat's electric system you should be able to do it -- but you may not be able to assign seat settings to specific keys. My '04 S has this feature -- mirrors and seat settings are tied to a key. I have two keys -- one for me, one for my wife, each with our specific settings. It's quite nice but just having the seat memory is nice -- which ideally you can retrofit just the harness to do. If not, ask if an entire seat replacement will do it. You'll be surprised how cheap used Cayenne seats are. People pull them from totaled vehicles or people dump stock seats for custom seats. I think all 9PA and 9PA1 seats are interchangeable. Also, call Sunset Imports (link here on Renntech) -- they can tell you and if possible can sell you the parts for a solid deal. They have used seats from time to time as well. All you really need is the driver's seat, the passenger's seat is not so crucial for memory settings. Once set-up you'll get in and push (and hold) a button (you/your wife will have your own settings assigned to a button, 1, 2 or 3). The hold aspect of the button is a hassle -- when I meet my wife and only her key is around I push my button and I have to hold it for four to five seconds. Not the end of the world, just a hassle. It may be a safety feature. Let us know what you determine and good luck! Update -- I just saw that you are not in the US. In the UK you'll of course be looking for a right-drive memory seat, not sure if Sunset Imports would make sense in your case. But do ask a Porsche dealer.

Hi -- two different issues at play here. ManMN has a potential problem and needs it looked at by a mechanic -- boyer2003, what your issue sounds like is standard Cayenne operation: when vehicle/emissions/exhaust/catalytics are cold you'll always start in first and the shift to second may be abrupt. Note that it's the vehicle temp which controls this -- not ambient temp. It will happen in both summer and winter when your Cayenne is cold and just started. I don't think you have any problem at all. Do this -- on your next drive that's over 20 or 30 minutes and the fluids are warm, turn off the ignition, pull the key out, then a few seconds later restart and get underway. You should start off in second. (Make sure PSM is remains on.) If you start in second all should be well.

Easy. It's your drive (cardan) shaft. Search in the Cayenne 9PA/9PA1 forum -- which is where Loren may move this thread. You'll find a lot of info on the subject -- cardan shaft. I had mine replaced at 60k/miles.

Very cool -- what year/model is your Cayenne? Did the problem happen all at once or slowly occur for you? And hey, Renntech helped you out, be sure to become a contributing member -- you'll get much more value -- and you'll support an excellent cause. Update -- read your profile and saw you have a '04 Cayenne Turbo. Take care. Edit: added update.

You sir, are quite logical. A bit more effort but an elegant solution nonetheless.

My '04 S does not pop the entire tailgate open but it unlocks it so the handle will open it. I do recall a DIY retrofit that adds springs so then the rear gate is remotely released it pops-up a bit. I'll look around for that info for you. For the upper glass window if you hold the tailgate icon on the remote down for two full seconds the glass window will indeed pop-up. This tidbit was detaield in the owner's manual. Pretty cool. And of course newer models have the auto open/close tailgate feature.

Be sure to check that the wheel & collapsible tire you find will fit in the wheel-well/trunk recession -- all 9PA/9PA1 Cayenne's have the same wheel-well trunk dimensions irrespective of model designation -- base, S, GTS, Turbo, Turbo S. Some early models have an extra battery, others a sub-woofer, etc. I've been looking for a very, very long time for some 18" steel wheels for a winter/off-road set-up but I can't locate any, nothing for the Cayenne, Touareg, or Q7. I can find lots of 18" OEM wheels on Craigslist and other places but I really just want robust steel wheels with the same 18" x 8" dimensions (and bolt pattern) as the OEMs. I have the OEM collapsible spare on a 18" steel rim (which perfectly fits in the wheel-well on top of/around the sub-woofer but it's a narrow wheel. My idea was to purchase four of them (the steel wheels which come with the collapsible tires) but I can't find them for a decent price and I'm also not sure how strong they are, and again, they're narrower then spec so I'm not sure if the wheels are designed for anything other than limp-home mode at 50mph with the mini collapsible tire. This may be of interest: how to install the collapsible spare. The same guy (David Leonoff) has some cool pics of the TPMS set-up.

Loren -- excellent summary and the PDF you sent is very helpful unraveling the mysteries of Porsche option codes as related to a specific vehicle and VIN. I donated again to Renntech via PayPal. Renntech is, by far, the ultimate online resource for information about Porsche vehicles. Renntech and its community of members has saved me time, money and provided a deeper understanding of my Cayenne.

I ran across my option code list sticker in my trunk this afternoon and was thrilled to find it -- it had peeled off. My manual does not have the option list. I bought my Cayenne used (a CPO 2004 S) and have been looking to research my options list. Somewhere along the line (perhaps when new at the dealer) 19" wheels were installed and some other quirks and mismatches from the vehicle to the options list exist. (18" wheels are option CJ6; 19" wheels are option CP7 -- my sticker notes CJ6 but I have the 19" wheels.) This site (Renntech) is stunning. The searchable option code database as well as model year order lists are an incredible resource. Access to the data is all the more reason for you non-contributing members to contribute. The data is so very cool. This site impresses me more and more -- and by the way I have no connection to Renntech or the staff, I just can't stop raving about how great this site is. My Cayenne has some options that are not on the list (original equipment PCM for example) and some codes are noted that I can't locate. 8DG, E0A, H9K, QG0, X7F with both the I and M prefixes searched in the 9PA and 9PA1 databases do not locate anything. If any one has any other option code resources please let me know -- other folks on the forums may find additional resources valuable as well. Attached are pics of my actual code list sticker as well as the Excel doc I put together to match the codes to descriptions in the Renntech database. Loren and folks are amazing, thank you!

Hi -- the auto headlight feature relies on more than the physical switch -- a light sensor, rain sensor and vehicle speed sensor are all part of what the auto light is based on. An earlier thread covers this -- and a search on Renntech may help with retrofitting to auto light detail. Be sure to join Renntech as a contributing member -- you'll be able to download DIY and technical service bulletins -- it's the best money I've spent in support of my Cayenne (2004 S). Loren and folks are great. For switch removal, from what I recall no tools are necessary, simply line the switch up to the proper point and a firm consistent pull is all it takes. Edit: Added info.

The best way to determine is to try playing a CD formatted with MP3s -- in dash as well as the rear caddy.
