Hey guys, several months ago I posted about a transmission problem i was having where my 04CS would not shift out of low 4. anyway I replaced the transfer-case servo motor but it didn't fix the problem. So through a few conversations with guys that know more than I, it looks like even after the servo replacement, I need to clear the old config/setup from the old motor. And we couldn't do it with any of the aftermarket scan tools we had available Does that even make sense or has anyone experienced that? anyhoo I thought Id find an independent in DFW to look at it and see if they can get the transmission working correctly. If so, i need them to also replace the water pump. can anyone suggest a reasonable/reputable ind. Porsche mech. in DFW? preferably north dallas/richardson/plano area. thanks for your help! John here's a link to the previous thread(s) I've replaced the servo motor and the console switch. I CAN go forward into lower 4 but it wont "back" out to normal. http://www.renntech.org/forums/topic/45658-i-replace-the-transfer-case-servo-motor-but-still-04-cayenne-s/#entry247489
doing the same thing. Can't switch out of low 4wd. Does anyone have any suggestions as to what to try next? I was thinking about replacing the running gear switch on the center console but not sure of the part number or how to get the console apart to get at it. Is there a fuse that runs that servo motor? My mechaninc cant feel any thing with his hand on the servo motor as I run the switch so it may not be getting power. any help is much appreciated. Here is a link to the previous thread... http://www.renntech.org/forums/topic/45593-04-cayenne-stuck-in-4wd-please-help/
is there anything to check for specifically?I mean how do i know if it's failed? i could give it a few "technical taps" and see if it comes to life. Should I hear it making noise if someone tries to switch it with me listening?
hey guys, I have an 04 cayenne that has been running fine. Well we got some a load of ice here in Texas and I had to get out in it. I put the car in the the low 4wd mode witch it seemed to do without issue but I thought better of it and tried to put it back in "regular" drive mode. However it's stuck in low. when I turn the car off and then back on, i try to turn off 4wd it does nothing for a few seconds and then a "4wd system faulty" comes up on the screen. I've tried everything I know to get it back in normal mode but I'm out of ideas. So a couple of q's... Is there a way to manually take it out of 4wd? are there any fuses/switches or whatnot that could be the culprit? Could the unusally cold weather have anything to do with it not disengaging from 4wd? and finally what are the chances of it operating normally once the temp goes back up around here? I sure hope someone has some ideas Im a pretty good ways from any dealer and obviously naked. Thanks in advance for any ideas. John
ok so I got the drive shaft replaced and she's purring like a kitten. So i guess ill try to figure out where this gas leak is coming from. I've read this thread : http://www.renntech....ear-wheel-well/ and its exactly my issue. What i cant figure out is which part is actually leaking? btw... this cavity was full of gas. this is the drivers side access panel under the back seat PTEC's reply with part # "RFM is right on the money. The most common cause for this is a leaking drivers side fuel tank flange. Should be part # 955 620 841 00. Due to the design of the tank, both flanges must be removed( there is one on each side of the tank) so you'll also want two sealing rings ( 955 201 133 01) There is an updated pipe that porsche wants you to install on the drivers side flange as well, 955 620 911 001." im a little confused what going on. what do they mean by "both flanges"? As usual, a BIG thanks in advance!!!
ok guys,,, all is well. drove slowly out to my buddies with the lift and about 4 blocks from my house all those PSM/ABS warnings cleared on their own. got the drive shaft replaced with my vertex shaft and all is right in the world. thanks for all the help and sugestions.
I haven't driven the car really since we're not putting the drive shaft on till tomorrow afternoon. I will see how it goes and hopefully eveything will clear itself up (fingers crossed) thanks guys!
PLEASE PLEASE PLEASE! I really need some direction. I replaced the battery and the car is starting beautifully. However, the PSM and ABS failure lights are staying on. Is there any way to reset these and see if they reappear? i'm miles and miles from a dealer.
I forgot to mention... the Battery that's under the seat was replaced last year and the one in the boot tested good. However the car is doing the same kinds of things it did prior to the replacement last year. weird lights. not locking properly. keyless entry doesn't work, lights are dim and then click off, just general weirdness is the best way to describe it. ( last night the right rear turn signal stayed on and then faded out after I locked the car ) weird
sorry, tried to be brief... ok so this is where I am. O4CS 97k Freshly naked then WHAMMO Drive shaft bearing fails. So while I've been deciding how to proceed it's been sitting under covered parking patiently waiting. My Vertex shaft will be here today and I hope to get it installed over the weekend, but here's where it get weird for me. So the other day I went to start the car just to let it warm up and relax since it's been sitting about a month. The car acted like it was dead, but after turning the ignition left/right then reinserting the key the light came on and the car started normally but with a PSM Failure warning. I turned the car off and figured I'd address it when I redid the drive shaft. so with the shaft arriving today I went again last night to start the car up, check the tires and what not as I'll be driving it a few blocks to my mech. buddy with the lift. again the car acted completely dead until i did the left right reinsert thing with the key. i proceeded to start the car and it sounded "different" and then I was presented with PSM warning and a brand new ABS FAILURE WORKSHOP. error. I started the car 3 or four times after that and never heard the odd startup. however the electrical system is acting strange like it did the last time i had a battery issue. the ABS warning scared the crap out of me until i started reading about potential causes. Could the bad/low battery ) mine has 2 batteries) really cause that much havoc in systems? Even though car started and drove normally? brakes were good and everything SEEMED normal except for the warnings. I am buying a new battery even though mine is not that old but it was DEF. dead and didn't seem interested in taking a charge from my trickle charger. If it turns out to be bad/low battery causing havoc, should the various systems reset after it gets good juice? ideas? thanks very much in advance! John
jplumlee started following 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
a couple of Q's for all you smart guys... I have an 04CS sitting @ 95k miles. The regular maintenance has been done, coolant pipes, plugs, coils, belts, etc... and overall the car is solid, However, 2 issues have recently cropped up: 1. about 4 hours after the CS went naked. i started smelling a gasoline smell from the drivers side rear wheel well. upon inspection you can see where gasoline has seeped, albeit very slowly, from the hole in the gas tank cover and my gas mileage has dropped dramatically. I THINK its the connections or flange on that side of the gas tank and it looks like the access panel under the back seat is the way to go at it but not totally sure that's where I should begin looking. ideas? is this common? expensive? (attached a pic) 2. I now have a CEL for P0491-Secondary Air Injection System and the F4 fuse was blown. Just to be sure it wasn't an isolated event I replaced the fuse and it promptly blew. I'm not really sure where to begin looking for the problem and I'm a pretty good ways from a shop. Is this a serious problem ? can the car be driven until it's repaired? expensive? no other codes or problems and the only performance diff. I've noticed is upon start it a little sluggish at low rpm's thanks for any help you can give. you guys are the best!
jplumlee replied to TopGun2000's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)I went with the Nitto 420s on my 04CS and couldn't be happier. Very quiet, great traction, wear well, and handling is spot on. they weren't as expensive as some other options. I think I paid 150 a piece at discount tire.
Could someone direct me to a DIY for changing the pads front/rear on a 04CS? I really can't bring myself to pay someone $1000 bucks for that (which is what my local dealer wants). I know it can't be that hard... I would also like to know materials/parts needed (sensors?) and what pads you all recommend. (oem or aftermarket) thanks for the help! Also... I just spoke with an "independent" repair guy and he said that you're supposed to REPLACE the rotors at the same time as the pads ???? I have never seen that mentioned in any of the brake threads on here. sounds a little fishy to me.
jplumlee replied to jplumlee's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)I have replaced the main (under the seat ) battery. the one in the back tested fine when I was having battery problems earlier. The thump does happens when braking.
My Cayenne S has a couple of strange things going on I was hoping someone can help me out with. Mileage is right at 84 k 1. Occasionally when I pull to a stop or slow down almost completely stopped ( like rolling through a stop sign :rolleyes:, I hear a single "thump" that seems to come from underneath the front passanger seats. It's not all the time and is always a single thump... any ideas? something loose down there perhaps? what should I check? 2 My key FOB's have BOTH stopped working. but one "actual key" will start the car, my other key will unlock it but will not start the car and gives a message on the screen that I can't recall exactly (needs programmed? expensive?) Also, for some reason when I unlock the car, my alarm goes off IMMEDIATELY, instead of the usual 20-30 seconds if I don't insert the key. not sure why this changed all of a sudden. 3. My instrument cluster LCD has been acting strange for a while... image kinda shakes and some of the data normally present is not legible. ( this comes and goes ) and I notice it more during the day. Every thing is nice and bright in the evening/night 4. i have the crazy servo thing in my dash... sometimes it sounds like something is alive in there. Is there a way to fix that? I do have some extended warranty but not sure if it would be covered. in conjuntion, the driver and passenger have seperat temp controls on the ac but the "fan speed" seems to be linked together ( seems like when I bought the car each person had control of fan speed) any way to "un-link" them? 5 finally, need some direction on brake pads... is there a good resource for pads ( low dust ) that you can recommend? I'll stop there for now, thanks for any help! John
