    Fuel Tank Breather Valve

    Can this be coded out? It's number 1 in this real oem diagram. https://www.realoem.com/bmw/enUS/sho...diagId=13_0912 Also here is a picture of my car,

    You'd need to remove it all and cap everything.
    I'm assuming anything can be coded out, I just have no idea how to do it.

        i am curious on this one as well, it's contributing to error code P0444
        stuck with this error for many years .. change the valve once, but no change,

        from one of the experience owner, it said it's electrical related, so ..wondering if i can just code out this error to find back my clean error free dash display

          some guidance is needed if someone can help.

          while looking at the DTC excel,

          purge valve error is controlled by the following location:

          so, am i looking at the correct 14-bytes highlight above? matches 0x24 at 0A location, then counting 14 bytes all the way to FF,
          and from the excel's guideline, i just code out the 13 byte (27) to (00), then flash the bin back to car, the check engine light trigger by P0444 purge error should be disabled?

          do i understand this correctly? Thank you~​
