Coming to the collective for some guidance on this one...

I did a few searches and found other posts with the P0441 code but were all pertaining to the Cayenne or Boxter. I have 07' 997.1 C4S and it is throwing this code. Here is what the Durametric Tool shows.





No rough starts
No slow starts
No Whistle sounds
Tried resetting but code came back after 1-2 days.
Have a new gas cap on order as a lost cost first attempt at resolution...
Any suggestions/thoughts?

Thanks in advance.

Did you ever find the cause? I've had this code pop up a few times. Cleared it and it stayed away for a while then popped up again a few days ago.

Do you think you need your Vapor Canister Filter for Carbon Canister replaced? Part # 997-201-501-00-M100

Did you check your gas cap? Is it sealing properly?

I had a faulty/worn gas cap and it was ID'd with a Durametric read:
'5504 Tank System Leak" FWIW. New cap and no return light.
