Likely just the voltage regulator and not the alternator...mine did the same thing at 20k miles. $50 later (Bosch VW part) and I was back in business. If you search, you will find the part number from a previous post I made. Porsche does not have a replacement part, but it's the same that VW, Audi and MB use.

Good luck and fairly easy to replace yourself.
