Hello, I have some trouble figuring out the vacuumdiagram for my 88 s4 na.
Can you please post some pics of your engine bay where I can see the vacuum lines, which ones connect to the rear of the tb and to the uim and lim. THanks

 

I can do one better than that. Color coded for your enjoyment.

The one connection between TB and UIM not shown is the one connected to the thermo wax vacuum switch.

 

thanks, but I already had that one, trobble is I have an european model without the egr valve. I want to see where I have to connect the thermowax and the vacuum line that comes out the intake. Please post some pics.
