I needed to have the car safety inspected either way, so at least its there now.

Everything was working fine yesterday and she ran perfect after I filled it up with fuel.

The solution was replace shutoff valve and replace carbon canister.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Got the part in the mail today, installed it and fuelled up with no more problems.
I came across this site after seeing a few people reporting similar issues with Boxsters and Cayennes, but didn't see much about the same problem with the Carrera.
Long story short. After I put any amount of fuel into my 2004 Carrera it has a hard time starting. The only way I can get it to work is by flooring the gas and rev'ing the engine. Even this solution doesn't always work and can take up to 4 starts for it to finally run.
I've had this problem for two summers now. Everyone keeps telling me to live with it, but it feels like playing russian roulette and one day the car won't start. I've spent quite a bit of money at the local Porsche dealership and it doesn't feel like we're making any progress, so I'm looking for any help I can get.
The first time I had this problem I brought it to the dealer, they:
1) Replaced the vent valve and said everything was fine. Next time I filled it up same problem.
2) New error code this time P046 ("Activated charcoal filter shutoff valve internal fault allowing fuel to enter engine"). The solution was replace shutoff valve and replace carbon canister. Next time I filled up had the same problem.
Can anyone think of anything we maybe overlooking at this stage?
Cheers!
My hard start after fueling issue was solved by replacing the regeneration valve in the engine compartment. A 5 minute fix and no problems since.

Thanks for the info. Were you able to install the regeneration valve yourself? Is it easy enough a mechanically challenged person like myself could possibly do?
I hope this works. Definitely not a professional piece but should work. just let me know if i can help further.

Thanks a lot, was able to find it on my car and just ordered the part now off Pelican. Will update you after I install it. I'm based in Canada, so the part will take a while to get here :'(
Did you have any rough starts after the regeneration valve was installed @gator996? Everything was working fine yesterday and she ran perfect after I filled it up with fuel. This morning when I started it, she started really rough. Don't know how else to explain it other than it was shaking fairly aggressively. I turned it off and started it again and it ran fine... Could be a fluke or maybe installed incorrectly (although it was fairly simple, don't think I could have installed it incorrectly)...?
Thought I might be having this issue:

Put a clamp on the secondary air intake hose and it started up with no problems. Everything was running fine for about 15 minutes then my car came to a crawl and the CEL started flashing. Off to the dealer I go...
Looks like solving one issue popped up another issue. Going down the rabbit hole I guess.
Looked it over with the mechanic at the dealer and read 'Cylinder Misfire', took out the coils and one side all three of them were cracked extensively which was most likely causing issues. Parts should be here tomorrow along with a nice bill from the dealership. I needed to have the car safety inspected either way, so at least its there now.
