Have a CEL on the Passat. PO456 - Powertrain. Evaporative Emission Control System Leak Detected (very small leak)
found a thread that suggests a purge valve http://forums.audiworld.com/showthread.php?t=2375447
I poked around and did some jigglin' but didn't really find anything. Unfortunately all those hose clamps are the crimp style, they don't have screws on them to tighten.. guess I could smash them all with pliers for grins.
Found another site that suggested a faulty gas cap. Given that I passed emissions about 2 months ago, I'm thinking that's not it.. though guess it could be.
Any chance someone here has fixed this before?
