    Volkswagen Passat B5 Discussion
    2004 V6 4motion Hi folks, My story begins about 12~13 months ago. I'll state the facts, and you can tell me if these issues are from a possibility of one source, or if I may likely have multiple problems. 13 months ago the car would sometimes need more than one turn of the key to crank, until...

    Volkswagen Passat B5 Discussion
    I went through all 700 steps to get to the alternator and have removed the two mounting bolts for the alternator itself, but the alternator still doesn't seem to want to budge. I thought it would just kinda fall out, but I can even seem to move it by hand. Any suggestions? The two bolts I...

    Volkswagen Passat B5 Discussion
    So my friend has been back and forth with this mechanic (not a VW specialist) like five times, because the problem never seems completely fixed. I don't know much about it, and I'm totally unfamiliar with the 1.8T, other than it also has an accessory belt (unlike my V6). So after all this...

  19. New alternator wiring

    B5 Garage
    My old alternator, 038 903 018 QX, failed and needed to be replaced. I bought a new used one, but somehow managed to read the wrong part-number and got a 028 903 028 (which is the old version of the one I had). It looks similar so I´m considering swapping them anyway, but the wiring is a bit...
