    P0441 fault evap emission control system

    I have this fault on my car, I cleared the dtc and it re-appeared. I have done a search and seems a common problem and people replacing the n80 valve but a lot of people continue having problems and they don't seem to fix it 100% then end up just leaving it, so before replacing parts for the sake of it my question is can you physically test the n80 valve? If assuming I should check the pipes for splits, any other advise would be appreciated

    I had this fault a few weeks back, I fixed it by removing the n80 and giving a couple of squirts of WD40.

    I believe you can test the N80 if you have a full copy of VCDS.
