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

Can you please provide the part number of the vent valve that needs to be replaced?

Use the photo on Post 6 and go to Pelican. Could be : 99611012906
Don't get confused with the purge valve at the filler neck.
Others will confirm from PET or you can google the PET

I'm resurrecting this thread because I've got the same issue now. Hard to start twice in a row after filling up at the gas station, and throwing P0446. A quick search here gives the solution, thanks everyone for posting the excellent pictures and advice for changing it out!!

It just torques me off to pay $200 for this damn regeneration valve. Probably 250 at the dealer. So I'm going to make an attempt to clean it out and repair it first. If I have any success with that, I'll report back with pictures. Chances are it just needs cleaning - I can't imagine that the solenoid fails.

Maybe there is much cheaper a VW/Audi part that could be substituted ?

Good suggestion. If cleaning doesn't work I could always try a generic $20 solenoid from the auto parts store. Just connect it to the existing hard plastic line. And maybe have to wire in a connector that fits. But it's just a simple normally closed solenoid vacuum valve, very generic in function.

Excellent - we need easily available, generic fixes like this. Sounds like the perfect project for one of our electrical gurus like Particleweave ?

Hey y'all:
I'm just posting here so that future readers who are searching for Porsche Fault Code 68: P0444 will find this thread more easily than I did.

I've been dinkin' around under the hood recently, and this code popped for me. turns-out I (somehow) removed the electrical connector from the EVAP Purge Valve under the left-side intake. I know I was messing around right there (i'll post about that later) but still don;t know how I knocked-off that connecter; it's a wire-retainer, and seems pretty secure. but I've put it back on and the code is not returning.

Thanks Heavens! haha.

If you don't need the entire line, it is much cheaper to buy just the valve from Pelican:It is OEM.

Otherwise you are paying $200 for a little hose.
