Passat Pd100 B5.5 - Passat tdi no boost, vacuum lines - justyboy
I'm looking for info or a diagram of the Vw/Audi AVB 1.9 Tdi vacuum hose setup

I've just replaced the stock Avb turbo with an Audi AWX (Gt1749va), whilst doing this all vacuum hoses we're replaced one at a time off and straight back on.
The air box was off for two days whilst awaiting an AWX lower boost hose so I think it's one from there to the Egr or thereabouts as I've probably mixed them up.
To sum it up the cars fine apart from no boost :-( this was part of the reason to fit a new turbo (sticking veins/worn seals), and a remap at a later date.

Any help appreciated, I've only been able to find the Jetta diagram online which looks a bit different. Brakes etc are fine, it's only a boost issue.

Thanks

I have a copy of this diagram on my work PC, I'll try and remember to upload on Monday.

It is like spaghetti around the airbox area with the vac pipes, one-way valves etc
