Connector seems to be missing a hose on my 5000s Quattro.
Engine seems to run OK but this worries me, There is a slight vacuum I can feel pulling in. I have the Official Factory Manual but it is not very helpful.
Attached is a picture of the mystery connector just under the Idle Stabilizer Valve.
At the left side is the Crankcase Ventilation Pipe coming in.Picture taken from firewall looking to front.
Where does the hose for this connector go? Looked everywhere.
Thanks for any help. Also just installed a Fuel Pressure Regulator kit w/guage to replace the original FPR, looks good. Saved $$.
