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.

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

Will this help if my car is sitting lower on the passenger side than the driver side? or, will I have to take it to dealership to have suspension re-calibrated? I too am having issues with faulty suspension code periodically.

Thanks,

Jon

I too am experiencing the same problem. I have a faulty suspension warning lamp going off every once in awhile. All I simply do is wait till I'm done driving, and turn ignition off, then when I restart car, fault is gone. I have noticed here recently that the passenger side of my Cayenne Turbo is lower than the driver side. It is approximately 1/2 inch to 3/4 inch lower than driver side. What can I do to fix this?

Hello,

I am having issues with my rear hatch. I have read a ton on this forum, and have tried all of the voodoo tactics that previous owners have posted, and I am still having problems. The rear hatch warning light comes on, every time I hit a bump, or pull up onto a curb to park. MADDENING!! The dash warning light comes on, and the interior lamps come on. Really annoying while driving at night. I have tried adjusting the rear window latch shaft. Not working. The latch itself engages properly. It seems to have 2 stage locking mechanism. Both stages engage properly when I push it to the fully closed position, and then I release it with the hatch release micro switch on rear outside glass. I have tried simply unplugging the hatch switch on the back side of the glass, but, no joy... I have a new micro switch, I will try replacing that. Is there anyone who has the same issue, and what have you done to fix it? I will take it to the dealer, however, It is out of warranty, and do not want to spend a ton of money for labor when I can do it myself. Please, If you have had this problem and it is now fixed, tell me what you did.

Thanks,

Jon

Hi,

I'm looking for a replacement driver side mirror motor, and switch. Can anyone tell me what the part numbers are for both? The mirror itself moves in all directions, it is fine. However, the motor does not fold the mirror inwards. I don't know if it is the switch or the motor, but, I want to replace both items, and need the part numbers. Will this part # work for me (9557312290401c)?

Thanks,

Jon

Hello,

Any help with this topic would be greatly appreciated. I turned the Mirror Control Knob on my 04 Cayenne TT to adjust both mirrors inward prior to parking. The passenger side mirror folded in properly. The driver side mirror moved roughly half way in, and then stopped. No matter how many times I turn the knob, the mirror stays in one place. (Stuck)! I can swivel the mirror in and out manually, however, the mirror is loose, and, does not appear to stop in the fully adjusted proper usage position. Is there a quick fix that I can possibly do to remedy this situation? Can I remove the bottom cover, and turn the mirror manually? Thanks in advance for any help!
