looked at all audi and vw tdi videos, not enough detail. the plastic tray is difficult to remove, the attached photos show the top of a valve, second picture shows the valve underneath the tray. the round piece is holding the tray down, I am not ready to force it up without knowing more. if I break the valve , reconnecting the hose with new valve is going to be a nightmare.
the manifold itself is already too tedious! Can someone please let me know how to release the tray?
FYI I was shocked at how clogged the air intake was with an oil soot- Audi should be ashamed. My egr valve is acting up and now I suspect it is totally covered.
all tips/suggestions welcome.
Thanks
JD
