Purge Valve failure n80

Purge Valve failure n80Today we take a look at more failed VW parts. This is the show where we look at how VW parts work, how they fail, and ways we can diagnose failures. We are looking at the Evap Purge Valve also known as the N80 valve. Something I didn’t mention in the video is, the N80 valve is called that because VW uses N80 as the identifier for that valve. Every valve, motor, and module is identified in a similar way.

    Hi.
    Great video and the explanation, thanks.
    But I do have a question in here, and it sounds like this:
    Should N80 valve work “always”? Mine clicks always, and I think that it should not, because after some time, the vapor from the fuel tank should be removed right? Should I replace this part then?
    Many thanks for any reply.
    Cheers

    Thanks for the informative video relating the Purge Valve
    issues. After many attempt’s of trying to diagnose the check engine light problem where I have my Passat serviced I gave up on them.
    I needed to renew my vehicle license ,so I took it to the people who do the drive clean test and they said this valve was the problem.
    They replace the valve and the check engine light has been resolved therefore passing the vehicle emissions test.
    I kept the old valve and inspected it after watching the video.
    I got a whole lot of charcoal dust out of the end where the inlet filter is located.
    Powering up the valve with 12 volts DC the solenoid now works and air flow is easily established.
    I will now be looking for a new garage to service my vehicle as they had 6 attempts at trying to resolve the issue including what they said was a new purge valve installed ,
    My suspicions are they never did put in a new valve ,but used an old valve instead, out of some other vehicle.

    Hey. Thanks for the video on the Evap purge valve.
    I have a 2000 VW Cabrio MK3.5. It’s dufficlt to fill with gas b/c fuel pump shuts off of I do t trickle it in. It also stalls occasionally, sometimes when cruising but mostly when decelerating at low speeds. It was see to hesitate occasionally.
    Could these symptoms be related to purge valve? Thanks. Kurt
