2009 A4 B8 2.0T oil/level or pressure? Follow up

[Nick]

My original post,

At low speed I have seen the oil can flash and give the msg "turn off
engine and check oil level"   Level is OK according to car info display
and I have a dipstick I purchased from the dealer.
Any history on intermittent warning?
Is there a way to see oil pressure in real time using VAGCOM?
Thanks for your help

The solution, ( I thought I had replied before but I see the list has 
been acting odd.)

The problem was a faulty  PCV valve.  At low speeds enough vacuum to 
deny oil to the pump!  The diaphram  was torn.   I don't have all the 
numbers before me but a new valve was $$.  I got a replacement diaphram 
from local FLAPS same day for much less.
