SO i am still working on the evap code PO441. I decided to test the valve itself as i had seen videos of peoole testing the valves themselves. It sounds like it should hold a vacuum on the side that goes towards the engine. Mine does not. The part came from Amazon. Does that mean this part iS CRAP? Or can you not tell by just testing the valve?

Previous thread for context, because I'm reasonably confident that not all Evap Purge Valves ever installed in a VW-Audi Group car are the same:

So you are saying that it may or may not hold vacuum?

No, that's not what I said. I personally don't know how your particular purge valve works or should be tested. I simply added a link to your previous thread regarding this problem because I think it's important for people to know what car & engine this valve is on.

They all work the same way but have different sized orifice for the application.

Simply put your lips :pto the cur-sed thing and pull a vacuum, if it is wide open you'll get a large leak code, if it passes a small amount the code will be a small leak. It should hold a vacuum for the readiness test to complete properly, basic settings 070 and 071. I replace so many of those things my tongue hurts from testing them.

Don't screw around with junk from Bezos purchase a real one.

:eek:If this was Uwe's bar I'd say something bad about the guy.

If that valve has any leakage from the vacuum side it's junk simply replace it. I've had many N80 valves that WILL pass 070/071 EVAP test but give it a few days and the check checkbook light is back on.

Mine will pass the leak test but the other test, not so much. Im not very hopeful even with the bosch part as i have read the the po441 could be other things too and the biggest mistake is replacing the n80 valvw right away. Seems to be a crap shoot code.
