CEL and gear popout - Please Help -
Wow,
For all that money you'd think that a Porsche would have a more complex computer. My lowly little Subaru WRX will store the codes, just like the Porsche ECU, but if will have a time and date stamp on it. If I'm driving around with multiple stored codes, I can defnitely tell which one came from which incident.
Are you guys sure that the Porsche ECU doesn't do the same thing?
I don't know about the Porsche protocol, but on my WRX if the thing that triggered the code doesn't re-occur in the next 5 start cycles, the CEL will go off. I suspect something similar has happened here.

ECU does store codes with time stamp. results I have seen were given in engine hours. Also indicates rpm and some other data. Not sure what the protocol is for turning off the CEL on non-recurrence. Disconnecting the battery for 20 minutes resets the ecu, but leaves the codes.

Yes, the reason the light is off is the error is no longer 'active'.
