ABF vacuum hose into the bulkhead
« on: 07 April 2010, 20:35 »
right so today i've been inspecting the vacuum hoses which run from the back of the inlet manifold into the bulkhead, there all pretty decayed. one which was particularly bad was the one that runs into the bulkhead between the heater pipes. i gave it a little tug and felt a snap. so i removed the foam insulation between the pipes and the white connector the pipe attatches to has snapped off. im guessing this dissapears somewhere into the heater matrix. whats the easiest way to go about getting to it??
cheers

What year is your car?

The one to the ecu is accessed by removing the plastic trim at the bottom of the windscreen (passenger side)

The one you have snapped off is for the auto heater controls.

that soundfs like the connection for the a/c system? if it was me, I'd have the dash undertray off and see if you can spot the other end of the vacuum tube. then re-route it thru one of the spare holes in the bulkhead :)

spot on, cheers! i'll give that a go. right, another question... out of the two hoses at the back which should go to the MAP sensor on the ECU



coz i'm sure i read somewhere that it should be the one on the back of the manifold closest to the throttle body. however this one goes off to a small blue valve and the other hose, at the back which connects to the larger black pipe, runs to the ECU.

The one at the back of the manifold above the VW sign goes to the ecu.

The other one is usually for the aircon
