Porsche Repair Questions? Ask a Mechanic for Answers ASAP
It would safer for you and your hip pocket, to have the car towed to your Porsche dealer.
Depending on what module/s are affected, would determine the reason for the no start condition.
That's what I would do.
I have seen too many people try their own repairs that end up costing more than the dealer would.
Hope this helps you, and hope the dealer will sort it for you.
That is a good question.
Water does not go well with electronics.
I would say the Body Control module is not recognizing your key to allow engine start.
The fault could be the BCM, a blown fuse etc.
I've seen many problem cars, and a lot with one-off faults.
Best for the dealer to look at it for you.
How did you go with your car problem?
I hope my advice has been of assistance to you.
