Hey guys, I've been reading these boards for a while now. What a great resource. I have run into a problem with my 2004 Disco II that I can't seem to figure out. It's got 115k miles on it and is currently throwing a P0441 code. I had it in the dealership a while back and they told me it was a purge valve failure. I bought a replacement purge valve and installed it, checked the fuel cap and its snug. It's showing a pending trouble code of the same P0441. Any ideas on what else it might be?
