  1. Fuel gauge reading FULL all the time

    General E46 Forum
    so recently my fuel gauge has been jumping up and down, even when im parked and now its stuck on completely full all the time no matter what. I have a 2004 330ci and i did some research on what it could be, i ran the OBC hidden codes test and it shows 240330 for test 6. my numbers didnt match...
