not my pic but to the right hand side of where the throttle body bolts on theres a pipe pointing towards you, that 1 and a 1 underneath too. cheers
 
on the crankcase breather there is a t peice. does the small pipe go to the inlet manifold with the check valve inline?
 
picture not working mate

it might go there, others will come along with the answer. im runnin a tdi the now and not looked at my aeb motor for over a year so cant remember now.
 
not sure about a 10mm pipe?

Theres a big outlet on top perhaps 20-25mm which goes to the pancake valve, then one underneath thats for the dump valve recirculation. Perhaps theres also a small one for the N75?

For the crank breather, theres a T-Piece attached to the Z pipe, with a check valve then a small hose up to the underside of the inlet manifold. The only other connection i can think of on the manifold is the front left corner of the plenum, which has a small nipple takeoff for the dump valve.

the hose from the t-piece to inlet is 1 of the 1s i was talking about, so thats that 1 sorted, where does the charcoal canister vent from/too on aeb? i think that is probably going to be my spare pipe just to the side of the throttle body ??
 
theres a few pipes round there. need a pic really....... the carcoal canister (vent from the petrol tank) will go to the inlet system somewhere.

any split/soft hoses/the one way valve in the beather system being gunked up.......... will need replacing as they'll be letting in fresh air in/venting fresh air/causing excess crankcase pressure/subjecting the crankcase to too much vacuum/causing the air mass sensor to be reading wrong.... and will be causing engine lights to be on/causing running faults etc.

need a picture of the pipe your on about to have any idea.
 
One on the left with the rubber pipe goes round to the N80 valve etc, one on the right goes to the breather T piece via the check valve.
