2007 997.1.  Carrera S Cabriolet

After I refuel the car it doesn't want to start.  The engine cranks but it won't fire.  It sounds like it needs gas.  I put my foot on the accelerator and floor it and the car will start.  I then have to keep giving it gas for a few seconds or it will die.  Once it get going it runs fine.  It recently gave check engine light and code is P0441.  "P0441 Evaporative Emission System
"Incorrect Purge Flow Present"
I've researched this and it seems that it is a faulty purge valve or fuel tank vent line valve that needs to be replaced?  Conflicting information on whether the 997 has a fuel tank vent line valve.  Has anyone had experience with this?  Help would be much appreciated.

Yep, I had the same P0441 CEL on my 2006 997.1 with the hard start after every fuel fill up.  The culprit is a bad purge vent valve.  Depending on the engine, I had M96 engine, I had to replace with part 99711012801.  Best price was from ECS Tuning.

The valve replacement is a 5 minute job... it's right above the alternator, on the top left once you open the rear engine hood.

Good luck!

Hi Phunboy.  Thanks for the response.  This is where I get confused.  My engine is an M97 but this part of the engine wasn't changed from m96 to m97.  When I searched for the part number at ECS  I got this message. I got the same message when searching for the part for the m96 engine or the m97 engine.

 

The following results were found while searching the entire ECS Tuning product catalog. Products listed below do not contain any applications that match your selected vehicle. The parts shown below were found by comparing your search terms against the known OEM part number or internal ECS part number. Before proceeding be sure to use the SELECT YOUR VEHICLE drop down menu in the upper left corner or be sure to check the product application guide before adding an item to your cart. If you have any questions about your part selection or vehicle application please call or email our sales team at 1-800-924-5172 or sales@ecstuning.com.

 

Pelican Parts has a write up on replacing this part and this is what they say about the 997 models.

If you have a 2005 or later 997 Carrera, Porsche has redesigned the tank ventilation system and eliminated many of the components and lines including the fuel line vent valve.

According to all the how to videos that I have seen the part that you referenced is behind the front passenger side wheel liner, attached to the line coming out of the vapor canister.

 

I also searched the parts catalog at Gaudin Porsche Parts emissions and fuel schematics for the part number and it is not there for a 2007 Carrera S or 2006 Carrera.

Any chance it is a different part number/  The part you referenced is $364.12 at ECS Tuning.  Does that sound right?  Again I really appreciate you responding.

Bill

      In the past two weeks my '04 CTT failed to start right away immediately after fueling up. The second time it happened to my wife and coincidently someone at the pumps just happened to have code reader on them. They were kind enough to offer assistance and the proceeding codes were read; P0441, P0011, P2403. Can someone help me understand these codes and prospective trouble shooting I will need to do so as not to leave wife stranded. Thanks in advance
       
      So, as usual due to time constraints I didn't look at codes list on site and rushed to asking forum. I found the codes in the OBD section, so I understand what they mean and I now ask is there anything I need to do about them beyond the reset that was given at gas station? one code was cam position and the other two were emissions related; (system purge flow and leak detection pump)
