Mark - you were right! I felt brave this morning, took off the battery and cleaned up the cable and put it together again. The break proportioning and the key ignition faulty alerts went away, but still have the chassis error and a headlamp faulty message. The headlamp could be from a weak battery ( I have been using the battery a lot without driving the car). Needless to say I will check all the connections on the driver's seat and the front passenger seat to see if anything else is loose. Also the back floor is wet - so wondering if there are any split wires there as well.
Thank you so much Mark! I will take photos of the other wires as well and post them here. There is no rush to fix it and just want to do the right thing. Knowing me, in the end I will just take the car to the Porsche dealer to take care of it (as I always do!), but at least it will save me a $$$ to point them in the right direction.
Thank you Loren, the radio is still the original, but I did have iPhone interface installed on the car, so maybe it is something they did. I have three wires that are covered with black electrical tape. If it is a ground cable can it be the cause of the faulty messages described above (key ignition faulty, break proportioning and chassis failure?
Hi Papagut, thank you so much for your hard work and research. I have exactly the same issues on my Cayenne S 2008 car. Lots of water in the front and back of the car and getting all the same fault messages. Unfortunately my case starts about 100miles away from home, so I had to manually override the P on the gearbox and drove the distance in about 5.5 hours. I confirm that the car drives in 1st/2nd gear, with all the GPS off and the parking assistance off. My headlights works and I believe also the break lights. After cleaning all the water from the matts and the carpet and the bottom of the car, I am now trying to investigate what is wrong. The first thing I checked was the corrosion of the split wires. I have only looked so far the driver's side and from the 3 splits I found 1 cable (the brown one) like in the photo below. There is no copper at all the two wires not even touching each other. Is it possible that the copper completely eroded and disappeared? OMG how is it possible that Porsche knows about this and they do not make a freaking recall? Poor engineering and definitely poor assembly work by the engineers. Anyways - my question is should I clean up the cable and make a new connection of the brown cable? Is it possible that they were never connected and just sitting there in the black electrical tape? Thank you for your help!
