P1023 problems
I had the dealer confirm the P1023 code and they stated the high pressure fuel pump needed to be replaced. I am taking it to my independent porsche guy to change the pump. Does anyone have any other information on this issue?

Hello,
I have the same error, p1023, piwis says:fuel high pressure too low during starting upper limit value exceeded porsche.
When i try to start the car after a day of not using it takes like 10 seconds before it starts and it also has a rough idle until i hit the throttle a little bit. I read a lot about a faulty high fuel pressure pump. But i don't want to spent over 1000 euros (or dollars) if it won't fix my problem.
What did you do eventually?
Kind regards from Belgium
