Winter Garage Issues


Vehicle Information: Model : Carrera S Cabriolet; Year: 2006; Mileage: 7000;

Once it snowed this winter I stored the car in the garage hooked up to a Porsche trickle charger. While it started right up after 10 weeks of non-use, a solid "check engine" light went on. The service report says P0300, P0301 & P0306 faults for misfires, perform DME reflash, set readiness codes." My questions are (1)what were these problems, (2)were they related to the long garaging, and (3) should I be doing anything else in the snow season? With many thanks.
