Causes and Fixes Volkswagen P0441 Code: EVAP System Incorrect Purge Flow 

Yes PCV is possible. Could you already fix it? what was it?

@@rambotheg6980What I understand is the ECU opens the purge valve and then checks lambda for a slightly fat mix(as some air is replaced by fuel vapor it should go rich) A faulty pcv should not cause a p0441 unless the engine is running lean? Maby an evap line is clogged or air a getting into the evap circuit somehow?

Same boat and no matter what I do the code won’t go away

I've bought 2 N80 - p0441, one stuck closed, other one was working, my mechanic didn't tell me that canister might be clought up. I've replaced canister, with new N80 - I thought it is broken regardless of what a new part was - but it was bad/closed, so I changed for the first one and it started to work. Check if your N80 is good, check for tank cap, check for leaks, check for the pipe(from tank to canister - if the air can go through - one direction - from tank to canister, try to blow and air should pass smoothly) and that is it.
