The other day I was driving on the way to get gas and my "Check gas cap" light came on, I thought weird but okay. I filled up and put a few extra clicks on the gas cap and then when I started the car it was fairly hard to start. Shortly there after the MIL P0455 came one, as well as a couple other seemingly related vaults during a VCDS scan. As it were, I just swung by the dealership and bought a new gas cap as the rubber ring on mine was looking cracked and the tether to it has broken some time last year and that had been an annoyance that I know had more reason to take care of. I have since fueled up once more and once again the car was hard to start after the fill up. This all makes me think it's the evap/purge valve, N80. It's never been replaced before, and still has those annoying crimp bands on it. I just want to run it by everyone and see if anyone has other ideas before I just start tossing money at the problem, especially since the usually code for a broken N80 is P0441.
