I have a 1999 b5 a4 1.8t auto. And I got a factory replacement diverter valve and went to put it in and noticed there was no vacuum line on the DV. so haven't put the nee DV in yet because I do not know where the vacuums connects?? So my question is where does the vacuum line connect from the DV? Where is the nipple that I run the vacuums line to. Sorry if my question dosent make a whole lot of sense. Thanks for any input you might have!

 

I do believe the dv vacuum line connects right here. on aeb engines, the dv line connects directly yht ehe intake manifold. on older 1.8s, they connect to a solenoid. although my engine is the new style, theis is an aeb manifold. just run a line right from the dv nipple to this nipple on the im. i believe it is supposed to be routed next to the coolant line for the turbo which is on the timing belt cover

 

I though that might be it but it seemed kinda far away. but thanks for the pic and reply!!
