06 Cayenne Titanium S PCM not working and Key probems
Hi all, newbie here hoping for some help from this great forum.2006 Cayenne S started losing voltage from not driving so I replaced battery under seat.Car was sitting for 2 years.No battery is in the trunk.Car starts runs fine with new battery but..Car has no Nav screen,radio is very muffled sounding,only can change radio from steering wheel not blank pcm ,rear hatch does not open or click and ac /heat blower not working.Key battery was dead so replaced battery and that does not work to lock unlock doors or hatch with new key battery either. PSM light on too.(Its not in off mode).Any one know where to start please? Ive tried 148 code and the main and trip press,and checked all fuses and pulled and replaced,all 3 fuse areas getting above 12v with key turned on.Any help is greatly appreciated!
