UK-POLOS.NET - THE VW Polo Forum

Hi everyone I have a Vw polo 2014 plate with error code P044100,
I’ve changed purge valve and charcoal filter and fuel cap, all OEM but code came back - anyone got any ideas how to sort this ? Thank you

did you check for any leaks in the lines?

Yeah m8 did a smoke test but no leaks all very baffling
