I am experiencing the same issue. Have you gotten any resolve on this issue yet? Jon
Fixed Problems!! Just bought and installed new battery. Everything is working great except for the radio controls on the Steering Wheel!! Tiptronic selectors work great, volume and all radio controls do not. Any Suggestions Guy's?? Thanks for the great advice. Spot on as usual. v/r Jon
Loren, Thanks for the quick response. Do I change the battery under the drivers seat? Or the one under the sub-woofer? Also, the vehicle information cannot be accessed thru heads up display in gauge cluster panel. Would this be a fault of battery being low also? Thanks, Jon.
My 04 CTT just recently shipped home from Europe. I picked it up yesterday. The battery was dead, and had to be jumped. I drove from Atlanta to Nashville. The turn signals are not working, and windshield wipers and bright lights, and fender well lights all not working. The sunroof was very intermittent in its operations also. Could it be a blown relay? Fuses are fine. Where and what number relay would I have to change? Thanks, Jon
Finally changed coils and plugs last night. Wow!! What a difference in performance! Thanks guys for all the expert advice. I truly appreciate it. Jon
Thanks guys. I will change all coils and plugs, and update status. It should be done by the end of this week. Thanks for all of the great advice. Thanks Loren. Jon
Thanks Loren, I will try that.
Finally!! CEL came on, and immediately diagnosed with OBDII. Code reads as follows: P0300 Random/multiple cylinder misfire detected. P0302 Cylinder 2 misfire detected. I finally started car today, and CEL immediately came on. Shut it down, and instantly diagnosed with OBDII. So, based on the codes, should I replace Cylinder 2 Coil? I will also replace plugs while I am at it. Any further guidance from renntech members would be greatly appreciated. Thanks, Jon
No CEL, hooked up OBDII and no codes. Drove down the street, and still sluggish. When idling, It smells like it is running very rich. Still no codes, maddening!! Should I just replace coils? Plugs are less than 7 months old.
No engine lights are flashing, and I will not operate vehicle at all. I am trying to order parts to do it myself. Thanks for the help. Jon
I had the same problem, and it was driving me crazy!!!!!!! I know this sounds stupid, however, I adjusted the latch rod mechanism out just one turn. (You may not have to do this). While the rear hatch was open, I lightly sprayed the latching mechanism with some WD 40. I know how dumb it sounds, however, the hatch has not come ajar yet, Knock on Wood!! I have a new micro switch that I purchased from local dealer. If it comes open again, I will change it out with new rear glass hatch micro-switch. Try it, see if it works for you. If not, I would go for new micro-switch. Hope this helps... Worked for me. Funny..
Hello, Cayenne started sputtering this morning. I have a feeling that it is the coils. It is acting like it cannot get enough power, and the engine is rough idling. This is the 2nd time that I would have to replace a coil. I do not have a durametric, and I am worried about driving it the 40 plus miles to my nearest Porsche Dealership. (1) Is there anyone here that has a DIY guide to changing these things out? (2) How can I tell which coil is bad? (3) What are the coil part numbers so I can order them? Any help would be appreciated. Fuel pumps were changed out about 1000 miles ago. I will try changing coils, and diagnose further after that. Car starts fine, Drives, however I have a huge lack of power. Thanks, Jon
I will order the parts, and let u know the results. I will also take it to the dealership, and let them calibrate suspension. Thanks for all of the great support guys!! Jon
So, what you're saying is buy the pump repair kit, and that should take care of my problems? How much is a new pump all together? Thanks, Jon This will also help with the ride height, correct? It is sitting lower on passenger side than drivers side. I will try it, thanks.
Thanks for the replies guys. I am sure it is the rear glass. Every time the alarm sounds on the dash, and the interior lights come on, all it requires is for me to re-open and close the rear glass. The rear hatch door is secures itself properly to the fully closed position. I have never had a problem with the door. I will double check though. Thanks, Jon
