2007 VW Jetta 2.5 Wolfsburg purge Valve replacement

2007 VW Jetta Wolfsburg Edition

Diagnostic Code P0455 Gross emissions leak

I first changed the fuel cap because it was the easies to fix and I got it with a good discount at the VW dealer. It wasn't the problem so I looked online and found out the most common problem that matched my issues.

My car would not start after fueling. In a VW forum post I found my issue could be caused by the Purge Valve. It stays open. so, when I fuel up, fuel vapors flow back into the manifold flooding the combustion chambers with fuel vapor causing the car not to start up. There was also a thumping sound coming from the rear of the vehicle. Which was most likely pressure from the tank being released because of the failed purge valve stuck open.

I have now changed the valve and my Jetta is now idling a lot smoother and the light has not come back on.

I also made this video because no one has posted anything about an 07 Jetta. Subscribe to my channel. I will also be making other videos for any new issues that come up. Feel free to ask me some questions if you have any.
