  1. Replaced the fuel cap before posting...cleared the code after and the CEL came back on 1-2 days later (see initial post). I guess I am at the 2nd step now :) Thanks for your continued advice!
  2. Thanks Loren, I'm trying be systematic in addressing things, starting with easiest to replace/repair to more difficult. Where can I find the tank vent valve - was thinking to check this out next? Should I just go ahead and replace? Thanks again!
  3. Hey Ya'll, I have been lurking on the forums for some time now and recently purchased a 2008 Cayenne TT. I must say, I love the car, drives like a sports car despit 5,000+lbs! Anyway, recently I had a CEL come on - no changes in the cars behavior, appears to start/run fine. I borrowed a buddy's code reader and the following codes came back: P2404 and P0455. I believe these point towards a large evap leak. I went ahead and replaced the gas cap with no resolution (I did clear the codes and they returned in 1-2 days). I wanted to get your opinion on what to do next. I did come across instructions on the replacement of the evap purge valve - should this be next? Any help would be greatly appreciated. Feel free to leave instructions on how to complete any recommended repair - I am hoping to do this myself. Thank again!
