nice article on the problem and possible solutions
https://www.yourmechanic.com/article...y-andrew-quinn
One not mentioned here but elsewhere is a grounding problem, seems there is/was an issue on the Panamera with a ground wire connection.
it has it's own TSB but I haven't had much luck getting much more detail on it

I replaced just gasket and not full cap assembly and still getting EVAP large leak code, think changing cap would have better outcome?

By the way, I can't find a replacement gas cap for the PTT on amazon. Where can I get one other than the Dealers?

Gas cap at the dealer is cheap. $36.92 if he sells it full retail But I don't think it is a gas cap issue. If the code is P0069 That is a manifold pressure code. P0069 code could include a faulty manifold absolute pressure sensor, a faulty barometric pressure sensor, a fault in the circuitry of either sensor, a faulty Powertrain Control Module, or even a dirty air filter. A PIWIS II or newer will likely give you more information

hoo, thread back from the dead 
as an update from me, I was correct and my issue was solely related to the hot start on a hot day after running somewhat hard - after clearing the code it has never come back.
and yeah the yourmechanic.com quote is a joke

Same here. Mind you I just purchased this vehicle two weeks ago. When the CEL came on, I was like "ohh crapper! My wife will kill me". After researching for a few hours and remembering that I was confused at one point while closing the gas cap during the drive home, I kinda figured that the gas cap was the cause. (Damn this is a run-on sentence. Please excuse the bad grammar) Plus, the car ran fine so I took out the Durametric and cleared all the trouble codes. I went on a drive, and it never came back. It scared the crap out of me though.

yep, I had had my car for only a couple week when I got my CEL, same thing "oh crap", I did some research and came to the conclusion it wasn't going to kill my car if I cleared it and saw what happened

Hello - All Would seem to me having a car this sophisticated one would think there would be a menu to show the code rather than bring it to a dealer especially when the code is for something simple.
Is there a way it will display the codes without the dongle?
Thanks

If you have the engine icon error any decent reader will do. If no engine light need Porsche specific one.
Someone please correct me if I'm wrong...

The car does have a menu that shows explanation of errors, in the cluster. Main menu, you go to info and messages. It tells you in common language what issue may be (very generic).
To get the specifics, you would have to connect car to diagnostics package.
At dealer or indy shop, it will be the PIWIS2 or PIWIS3.
At home, you can use durametric, get knockoff PIWIS2 (north of 3k), or other diags package that reads/resets codes. Those except PIWIS2 are limited.
The car is sophisticated, and for that exact reason, designers at Porsche want someone with some knowledge looking at the car, to fix it right.
If you have check engine light, there is always a reason behind it. With old cars from 80s, you could drive your buick with CEL on for 100k miles.
With this expensive car, doing same may result in extra expensive bills. So it is always best to diag what the problem is, so you understand, and take measures to fix right.
Just my 2 pesos worth of info.
