Hey guys I purchased my first TDI about 3 weeks ago, an 02 Golf 4 dr. and I just have some general questions about it. I have noticed people talking about venting their gas tanks, can someone explain something to me? I have noticed when Im filling up that the gas handle will stop by itself, and you can hear air coming out like venting. and last time I added another gallong or two just by putting in more and waiting for it to vent by itself. Is that how you get your 14.5 gallons or will that be more? I know some other people vent different ways too, what are all the tricks? Thanks alot
