I have a 2000 1.8t passat. I think the leak is coming from where the DV valve is connected i would show pics but im still having trouble posting pics. but i think its from the inlet hose that connects to the dv. if u look on this site http://home.comcast.net/~hhong4/forgeinstall.htm its the second pic and it would be #17 but where the dv connects. If u lookk at the 3rd pic then its where the hose clamp is. I dont see any other oil residue except on the dv and this hose. What could it be? Im replacing all the vacuum lines should io just replace that too just to be on the safe side??
