I have a 2007 997.1 C4S that is throwing a P0441 Code - "Fuel tank ventilation system: Below Limit". Here is Durametric readout.
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?
