I have a 2005 cayenne s with 100,000 miles. Recently when I start car I get a few different workshop messages and the only guage that will work is gas guage. I get no dash lights, radio doesn't come on with out me turning on, wipers won't work, and turn signals don't work. It's almost like the car doesn't sense that's it's been started. Anyone have this problem before?

Normally I'd say check your fuses but for Porsche I recommend taking it in to a dealer. When was the last time it was serviced?
