Meanwhile...
Is it safe to drive the car? Without knowing the exact codes, can't be sure. The general rule is the Check Engine Light (CEL) solid it is ok to drive and CEL blinking get it flatbedded. But with so many fault conditions.

Has anyone any idea what and how to fix this condition? Not sure what the condition is without the codes.

You don't want to jump from symptoms to generic codes. Rather go from codes to Porsche DME (Engine Computer) specific codes for your revision of firmware to the DME manual's description of the probable faults and the flow chart of their diagnosis.

My guess is a faulty ignition switch.

Get the codes read...then post them all and someone who has the manuals will post back with specific descriptions.
