04 Cayenne Turbo Electrical Issues

[mojoracerx]

My 04 CTT just recently shipped home from Europe. I picked it up yesterday. The battery was dead, and had to be jumped. I drove from Atlanta to Nashville. The turn signals are not working, and windshield wipers and bright lights, and fender well lights all not working. The sunroof was very intermittent in its operations also. Could it be a blown relay? Fuses are fine.

Where and what number relay would I have to change?

Thanks, Jon

A bad or low output battery on a Cayenne will cause all kinds of strange electrical faults. Start by replacing the battery.

Loren,

Thanks for the quick response. Do I change the battery under the drivers seat? Or the one under the sub-woofer? Also, the vehicle information cannot be accessed thru heads up display in gauge cluster panel. Would this be a fault of battery being low also?

Thanks, Jon.

The one under the drivers seat is for most all electrical functions. The one in the rear (if you have that option) is only for starting.

After battery replacement chances are you'll need to clear all fault codes to properly reset the modules.

Fixed Problems!! Just bought and installed new battery. Everything is working great except for the radio controls on the Steering Wheel!! Tiptronic selectors work great, volume and all radio controls do not. Any Suggestions Guy's?? Thanks for the great advice. Spot on as usual.
