Hi,
I'm new to this forum.
I am having limp mode problems with my ALH TDI.I have replaced VNT actuator and vacuum lines. I wanted to rule boost leak out before replacing n75 or MAF and am trying to do a boost leak and have read 1000q boost leak post but am not doing it correctly. I have corked hose to breather (black puck on valve cover), removed oil cap, and baggied and clamped intake hose after air cleaner box. When I apply 10psi to hose just downstream of check valve after n18 valve I hear air bubbling in the crankcase so no pressure is held. Where exactly do I introduce air?
Thanks for any help.
