Hi guys, looking for a little help with the vacuum system, I could either do with a vac diagram for my Bora 4motion or some info on where the open end of the tee goes in the following picture....
TIA

There should be another tee further along that line: check behind cyl. 2. A braided pipe thing connects the pair of them, looks like it's missing. On mine the pipe frayed due to heat and it left a nice trail of oil down the back of the block. Costs approx. £30 from VW but you get the black pipe too.

 

...If there's no other tee along the pipe, then I'm thinking of something else.

That'll be your vac leak then :) The hose on mine goes from there to the underside of the crank case breather pipe near the elbow that connects to the intake pipe. I'm guessing that's the clear reinforced PCV hose in your pic

search part number 022103474B (or maybe 022103474G for a revised version?) you'll see there's a PCV pressure control valve in that breather pipe that is actuated by that missing vacuum line

Thanks for that! I guess I can just blank it off then as there's a catch can on the end of the clear hose now.
