  1. Does anyone have a trick for getting the brake booster rod out of the brake pedal? Or do you have to suck it up and use the Porsche tool? 2004 Cayenne S.
  2. Clearing the code worked. But I thought P codes were powertrain? Plus, why did it throw a check engine light for an HVAC issue?
  3. Hi Guys and Ladies, Had a weird one today. Anyone know what a P8448 code on a Cayenne GTS might be? It comes up with the Siemens engine control module. Thanks in advance for ideas!
  4. Found the culprit... passenger side vanity mirror. Power lead was crushed by the attachment screw and shorting it out. Pulled every light and put them back one by one till something bad happened. Old school...
  5. Got it. Thank you. Apparently the melted center contact is a good starting point. But still doesn't seem to make sense for all the other lights too. Maybe Miss Piggy just wants to spend some quality time with me. Haha.
  6. Does anyone have access to a 2004 Cayenne S wiring diagram? My interior lights will not come on. Fuse 12 was blown, and it blew again immediately upon replacement. Now it seems to not have blown but no lights come on. I'm trying to find the branches that come off of fuse 12 in the drivers side dashboard.
  7. And yes, we have the IPAS codes... just not sure where to enter them in the PIWIS.
  8. Yup... we got the PIWIS connected and can see that it says "Immobilizer Active" with a picture of an open circuit. We are trying to figure out how to change its state and apparently that TSB has some info in it on how to do that.
  9. Nope... lost the key. New key purchased from the dealer but as soon as we unlocked the car with the tumbler, the alarm started going off and now we can't get it turned off. The PWIS won't recognize the "alarm system". We pulled the immobilizer box out and can't figure out how to reset it so we can program the new key with RF pill.
  10. Trying to replace a lost key on a 2002 996. New key physically unlocked door but now alarm won't shut off. Apparently there is a TSB 213 on dealing with this issue. Anyone have access to TSB 213? Thanks in advance.
  11. Someone here must have dealt with this issue already... I sure hope!
  12. 2003 Cayenne S So my wife's pepper had a fishbowl in the passenger rear taillight for awhile now. I guess long enough that it shorted something out as the running lights no longer have power. I have 12V going to every pin in the connector except the common orange wire for the dual bulbs in the bottom of the tail light. Brake lights, turn signal, back up light work just fine. The fuse on the passenger side panel is in proper working order. I believe there is a controller box for the taillight somewhere in the rear cargo area (not the tow controller, the actual taillight controller). I am guessing that the driver for that power line has shorted out since I cannot get 12V on that one single pin (I think it is pin 3; grey/red strip wire). I have the rear cargo area torn apart looking for the control box with no luck finding it. The cable harness branches and comes back together in so many places I cannot identify where that Grey/red stripe wire gets power from. Does anyone have knowledge, or a graphic of where that control box is? The wife is getting pissed that she can't drive the truck at night for fear of getting pulled over by the police. Any help is greatly appreciated!!! -JB
