Success! Finally fixed the hard start while hot and fueling issues.

[ALEX SOL]

bringing up an old thread though seems a common problem and not cheap fix.

question: does the pinch off the line work? and does it throw a code?

I have ordered a 'bosch' type inline regen valve and will slip in over the weekend... and report back!

my issue is hard starting after fueling up. p0440 cel

i need to crank the engine, while massaging the gas pedal to floor and back a couple times, then sputters to life...

also have a lumpy idle / hunting idle.... quite annoying... check coils and change spark plugs.

while in the engine bay found two hose clamps loose and intake boots undone... so likely my vacuum leak...

question now is; would this cause the p0440 cel? I found these:

P0440:
Faulty EVAP canister purge valve - have no difficulty filling the fuel tank

Blocked fresh air line - not sure what this might be

Leaking EVAP purge valve - most likley

Leaking line between EVAP canister and intake - possible though not clear what's the sympton

EVAP purge valve incorrectly installed - never touched this b4

some mentioned the p0444 cel, here's a good fix... busted wire!

Alex Sol,
Any updates ?

I have the exact same two issues:
1. Crank but no start after filling up with any amount of gas. Pump the throttle while cranking and eventually if starts. If you let the car idle in the first few minutes of driving (e.g., stop sign to get out of gas station), the car will stall again.
2. Lumpy idle on occastion.

I bought the part mentioned above (Purge Valve 99611012906). Nearly $300 , my mechanic suggested I buy the Porsche branded part since he has seen the aftermarket ones fail. Haven't had the chance to install yet since the car is currently stored in another state.
