"Fault of engine control system"

As a side note, the new dash software update has changed the "fault of engine control system" warning. I believe that previously if the warning was in yellow it was still safe to drive. If the warning was in orange or was blinking then the car should not be operated. Now, it says something like "fault of engine control system ok to proceed driving"

If you get a yellow warning, you can keep driving based on my reading of the manual. Yeah, I read it when I first got the car. Anything red, you park and call the tow truck.
With that said, better safe than sorry, but I bet its not going to be anything major and will be covered by warranty.

That new software update to the warning should really read "Fault of engine control system" "Still OK to autocross"

Got my car back today. They ran the codes and the cel registered as an evaporator leak. They tested for the leak and couldn't find one. They said I might have left my gas cap loose, but I'm pretty careful about securing it after each fill. We'll see how it goes.
While the car was there, they also replaced the covers on the door stays and some "switch element for the filler cap".

Clearing Fault = Problem?
I own a 2013 C2S, and got the "Fault Engine Control..." info/warning on my multi-display, and yellow check-engine idiot light, the other day. After reading many posts, I decided to check my fuel cap, to be sure it was well seated. When I pressed on the oval pop-out panel to access the cap, it wouldn't press in far enough to unlatch the door. Found the circular tab inside the passenger door jamb, pulled on it, which popped open the door. I reset the fuel cap, making sure it fully seated, and made sure that the pop-out door worked again. It did.
My question is: If I clear the current fault flag in the ECU, can I count on the warning message reappearing if the mal-seated fuel cap turns out not to be the problem? And that if some other component of the emission or fuel system is the culprit, I'll be warned, as before?
I'd assume so. But I don't know how the monitoring system of the ECU behaves, and can't be sure. Thank you!

Okay... So, I called the dealer to make sure if I cleared the fault code, and if the fuel cap was not the issue, that the fault would trip the sensor(s), and redisplay the "Fault Engine Control..." message. They said yes, to try it and see if it reappears. I'll drive it next two days, and see.
Here are a few snaps of the iCarSoft display, and screen messages, when I used it. I then cleared the fault.

This happened to me. Injector or something replaced under warranty and off I go. Nice not to have any engine/software mods when this happens. I only say that because.... you know,,, I want engine/software mods. Silver lining.

Okay, so, after clearing the fault code (i.e., DTC), reseating the fuel cap, and driving the car for two days, everything is fine. I've cancelled my appointment with my Porsche service department.
Hope this has helped someone. My take away is that the 911's systems are just very tightly monitored. Consequently, having an understanding of the fault coding system, and the code types, is important. That, and an iCarsoft (or equivalent) unit is a useful tool to own.

I just had this exact same issue and error code. After resetting the light, it would stay off for a few weeks and then comeback. Turned out to be a faulty evaporator control valve. My gas cap looked fine and was fine.
