http://www.myturbodiesel.com/1000q/a3b4/ecu-hose-chip-tdi-65535.htm Have you looked at this FAQ article? It's the first on in the mk3 section because every mk3 will have this problem. It normally throws another code but perhaps if you trace that vac line and double check all lines, you may find a bad one or bad check valve.

Also what does this mean? " have fuel up to pump without resistance"

as stated before more than nce i have changed the ecu line and i mean by no resistance as in there is nothing inhibiting the flow of fuel just a tiny bit of vaccum applied and fuel comes out of filter.

Sorry, I read the post and didn't recognize that it was continued from a previous post. If you feel it's a separate issue, that's fine but if it's part of the old issue it should be continued in the same thread so that people can read it in one place.
