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

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.

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:



TIA
Tom
