On the way to work this morning, my 2002 MK-Iv(A4) was acting strange. I noticed that the boot was way high even though I wasn't romping on it. Then I felt a slight surge and the boost dropped to next to nothing ... maybe 5-6 psi tops ... and not much power.
Could it be my actuator or vanes getting stuck open or close? About a year ago I took the actuator linkage loose so I could work it to feel how smooth it was. I did feel a slight hesitation at one point.
I have a mitty vac so I can try to work the actuator and see what happens or take it loose and work it by hand and see how that feels.
I know to check to make sure the actuator is holding vacuum.
Beyond what I've already stated, I don't know what else to check to trouble shoot the problem.
Turbo is a VNT-15. I doubt it has anything to do withthe intake as I have a DGRP and it gets run up to 4500RPM at least once a day and I normally shift above 3k when warm.
Thanks!
