Hi guys!
I am getting the same error over and over (only P0441 incorrect flow). Before it took time to show up in VCDS and did not trigger a MIL so I just ignored it. But now it is there frequently and often triggers a MIL ON when stuck in traffic for a few minutes with an hot engine. So it has developed progressively.
I ran the output test on the N80 and it seems to click well. Moreover I disassembled it and tried to blow through. There was quite a bit of resistance but I could still blow through (like if you did it on a functional closed thermostat) not a complete sealing but takes pressure to blow through. Not sure if it is supposed to be completely sealed or not?
As the issue was very intermittent and slowly worsening, I guess it is either a clogged pipe, N80 or saturated cannister or gas cap? The car runs good apart from that.
What would you say?
Thanks
