2012 Cayenne S with no interior power when turning key


Recommended Posts

I have a 2012 Porsche Cayenne S with an odd problem. When I turn the key all I hear is the fuel pump prime, sometimes I can hear the radio buzzing from the rear drivers side door speaker but other than that nothing else works on interior. Sometimes the drivers side window will roll down and sometimes the sunroof will work but its off and and of coarse the car won't start and it doesn't even click like it wants to start. When I press the trip computer button on the gauge cluster the cayenne logo pops up along with the mileage also the parking brake light illuminates when the parking brake is engaged. All exterior lights work but the steering column controls aren't working either. Hazards come on when pressing hazard button headlight and DRL's work. Battery is brand new and I even went back to the auto parts store and swapped battery again with no help. Does anyone know what this could be. Also I tried the pyro fuse by hardwiring it but it made no diffrence. When I scanned it a ton of codes popped up that said voltage lw and all the computers. But the battery is brand new and I am not sure if there is a second battery that would make a difference but I would love to get this car up and going. Thank you for any help in advance.
