Comes out of bulkhead where water in/out pipes are for heater then travels under scuttle to a grey plastic junction with another vacuum pipe. It fits onto a white nipple coming out of bulkhead,,,,,, ta Link to post Share on other sites
VR6Pete 1,455 Posted July 23, 2013 Report Share Posted July 23, 2013 Think my old mk3 had this, and was something to do with aircon / climatronic... Does yours have air con? Link to post Share on other sites
UnitedMotorsport 55 Posted July 23, 2013 Report Share Posted July 23, 2013 Its how the servos on the flaps in the heater box get their vacuum supply from the engine bay. Link to post Share on other sites
bennyk 1,238 Posted December 3, 2013 Report Share Posted December 3, 2013 (edited) Could this explain why I seem to have a noise like an air leak under my dash? And my blowers are useless when trying to clear the screen? Mine has climatronic. Edited December 3, 2013 by bennyk Link to post Share on other sites

bennyk 1,238 Posted December 5, 2013 Report Share Posted December 5, 2013 Looks like I've got another job on the list then, remove half of the dash to find an air leak! Link to post Share on other sites

Hopefully it's just something that has come off and that you don't have to strip everything out!There is a good guide on here that covers replacing a heater matrix so should give some good insight on stripping your dash!Might be worth replacing the matrix while your at it to be honest Club Chairman Link to post Share on other sites
