Remember This Thread "Exhaust+Boost Before & Affter". Could it be My PCV Valve?

What part of it usually fails the actual valve or the hose

I was wondering if by any chance could it be my PCV valve (instead of the exhaust
) that is acting up because I have been only loosing 2 to 3 PSI.

Has anyone done this

Ps: Its not the Dv failing, I just had it checked when I did my oil change yesterday.

what about re-calibrating the diverter valve since it is seeing less pressure, it may be not opening fully? just a guess...

i wish i actually knew what your talking about. i have no idea what that valve is that you are showing :(

How does one recalibrate the DV? There's no such procedure in the Bentley for this AFAIK

Do you have any oil around the fill cap? Do you have any boost codes when you run vag-com? If you have lost boost it is possible that it is bad.

It is the valve not the hose.

i will have to vag the car tomorrow, but I don't have oil around the fill cap.

Actually meant to get an aftermarket DV, cuz your right, how does one recalibrate the DV? duh...

HID: If the DV has failed, it could be leaking boost. I think it's very coincidental that it failed right after putting in your exhaust though...

Its not the Dv, I just had it checked when I took my car for service on Saturday. The only thing I failed to mention to my service adviser was to check the pcv valve.
