should the pcv valve be sucking air thru the top of it at all times? im getting a lean reading on bank 1 and bank 2 is this normal? if i block it with my finger the engine speed changes

No. Are you checking the round crankcase vent valve? The top is a solid plastic casting.

Needs a new one.

you probably need a new valve. Trust me on this...purchase an genuine Audi brand. I just went through 2 inferior valves and finally paid the money for OEM. I purchased off ebay from an Audi vendor ("audi.exchange") as it was the cheapest with free ship. He shipped fast too.

Replaced valve took care of the problem thanks for all the help i received

Hmmm, I've been driven nuts lately by those codes, if this works I'll buy you a beer!

Does yours have the hose off the top or the vented "puck", and where was the air going? Through the vent?

Vented like mine:
