In the 8 months I have had my 2003 Cayenne S the TPMS stopped working, the horn on the door open/close will not work, the comfort settings to open all doors will not retain that memory for more than two days. Now it has gotten really bad though as the comfort settings has completely disappeared, the dash dispaly has gone very dim, the radio and nav no longer show on the dash display, the fuel gauge reads empty and I just noticed that the odometer and trip odometer are not changing. Anyone have any idea how to fix this barrage of faults? I've had it at the dealer for other problems that have now been resolved but they didn't always fix the problems with the first thing they tried and they are very expensive. I am not loving my Porsche experience like I thought I would. It drives so well but all these silly electrical faults have really taken the shine off of it. I thought it was supposed to be Italian cars that had poor electrical systems? Please, please help if you have any idea so I can talk to the dealer with some knowledge rather than be ripped off again.

Have your batteries tested.

When a battery is about to die many strange e,electrical problems start.

Front battery was replaced about six months ago and when the big batch of problems started my local Porsche mechanic immediately checked the rear battery and fuses but said there was no problem there.
