Trying to figure out what the correct setup for the vacuum lines are... and after hours of trying to search online I've come up with this setup (digram above). Is this the correct way?

It used to have an AFN before someone installed the 1Z.

nobody knows...?

I used this... Although to be honest it starts to make sence after you have a propper look...

Thanks for the link... that seemed to sort out the N75 Valve. But still need to figure out the N18 Valve and other hoses... The previous engine was from a Passat, no idea what code as it was as it had been taken off... could have been an AFN but cannot be 100% sure. Now has a 1Z from a mk3 1996 Golf 1.9 TDI.

This are the valves and other things it has ...


The N18 Valve has a missing nipple so I gather I need a new one if I need this in the setup...


What I thought was a tube coming from the air filter is actually from the ECU. So this air filter setup has no connection point for a hose:


Im no expert and been trying to solve this by searching the web but have not come across anything that makes things clear... any sort of help would be appreciated... Thanks

I find the workshop manuals quite good for this sort of info, also the self-study guides are really useful too, eg. SSP153 has a couple of diagrams of the hose connections, and explains how the TDI systems works.

I'm still learning about my 1z engine, but I know where those components are on mine:-



So basically you want to know what those blue tubes are connected to right? I haven't got my van with me as it's in a friend's warehouse at the moment, but will hopefully get over there later this week, and will take some pictures.
