Mine turned out to be the battery (I did not get a Porsche battery to replace it). I did have the battery replaced at the shop (independent) since I did not have radio code and didn't want the hassle. Turns out the shop couldn't get the codes to take and tried to give me back my car without a working radio, they offered to only charge me for the battery and not the labor!
Well they kept if for another day (gave me a rental) after I "protested". They got got the codes to take but told me that the 2 nearby Porsche dealerships wouldn't help them out with codes and thus the delay. I guess the $100 for labor was worth it. But I have the radio code now.
