thanks for posting your experience. and not sure if it can help me but i think if you could post the letter you sent to VWOA it would be extremely useful for some of us going through the same thing.Use words like "explosive liquid" "children" "disaster", you'll get more response. Trying to take the normal logical route isn't going to get you anywhere.
Skip the dealer, go straight to VW USA, keep going over heads if you have to, the proper chain of command will keep getting you the same answer. I don't know if I still have the letter I wrote on my computer if I do I'll post it.
I bypassed dealer completely and went right to VWOA. After a few calls, I spoke to regional case manager/supervisor and used all the dangerous words you provided- explosive, fuel leak, children, etc. And btw- I do have 2 kids under 10 years of age that drive in the car with me most of the time! And I live in CA, the most firestorm friendly state in all of US!
At any rate- they basically told me, in a very nice and patient way, to piss off. They said my car was too old, had too many miles, was out of warranty, etc, etc.
And they said that is was a GLS. So regardless if the recall was not complete or part replaced, the recall that covered the faulty ventilation valve was only for 4motion passats.
Therefore the dealer was never required to drop the tank to check and replace part. They said since the faulty built-in ventilation valve wasn't included in the original recall for GLS models (only the heat shield for the fuel lines was recalled), if it is faulty now it's my problem to fix, not theirs.
They could care less if I had to junk it or if it caught fire with me and my kids driving around in it.
I'm keeping my fingers crossed that it was just the fuel pump seal.
