I replace the fuel filter and nothing changed.

Today i drove till the fault code become Current. I check the Acual Value and both banks where beyond the limit with smaller value than specified.

DAS suggest to check the sealing rubber that connect to air filter housing, the value for air mass meter and the O2 sensors.

Everthing (on the same time as fault code was current) is it perfectly.

So, I test till now with DAS within Acual Values and Actuation menues:

actuation of the camshaft - all 4
O2 senzors - all 4
air mass senzor
intake presure senzor

I have no other ideeas, please help!
