2003 Cayenne Turbo will not start

[Pkscheldt]

Three days ago after driving my 2003 Porsche Cayenne Turbo (Minnesota) I parked, it sat for two hours and then when I went out I put the key in the ignition turned it to the right and nothing happened, no click, no mechanical noise I typically hear when the key is inserted. I have a message on the display that says Move Steering Wheel. The steering wheel is locked as is the gear selector. Interior lights work, stereo works, running lights and tail lights work.

Windows, sunroof, headlights, and ignition will not work. I cannot get a connection to my durametric either. I have replaced the rear battery, (front battery is 2 years old) both relays under the seat and disconnected the batteries for a few minutes.

In the last few weeks prior to this periodically when I tried to start the car I would turn the key to the right and sometimes nothing would happen, then remove re-insert key and it would start fine. Once I inserted the key and turned it to the right and the starter engaged and then stopped prior to starting. I removed key and re-inserted and it was fine.

My contact at the local dealer is recommending that I change the ignition switch.

Any thoughts will be helpful.

Many Thanks!

Regardless of battery age it could still have failed so you need to have it tested. Just a note: you don't have a ignition switch in the regular term but a start control module.

Well, I came back from a trip and started again on the 2003 Cayenne Turbo.... Replaced battery under seat, no change. Replaced ignition switch/module, no joy. Any help will be much appreciated.

Do you have the optional second battery in the rear - if so that is the one used for starting.

Thank you Loren and wvicary. Yes I do have the 2nd battery. I just replaced it as well, double checked all terminals. I'm about to start checking every fuse with a tester. I have to imagine I'm missing something fairly simple.

Update - The car has been at the P Dealer now for 30 days. Just heard that "Kessy is not recognizing the electronic steering rack" and They need to install a new one. It has taken 12 hours of labor to get to this point. Does this seem reasonable.... I'm a little suprised at the amount of time to troubleshoot.

It looks like a new steering rack and 6 hours of labor more to go.... Thoughts?

Confirmed.... A new steering rack and she is back to good
