    Volkswagen Passat B5 Discussion
    2004 V6 4motion Hi folks, My story begins about 12~13 months ago.

    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...
