    Hi all

    I am having problems with my 645 . The dash lights up like guy fawkes night when i drive it.
    I have viewed the threads about alternator problems and im looking some advice please.
    Can someone tell me what used alternator will fit apart from the 645 one, for example will one from a 745 or 545 fit?
    Just i think it will be difficult to find a 6 series one compared to a 7 etc.
    Also anyone recommended a good place to get second hand bmw parts.

    Thanks in advance

    find your car in www.realoem.com. Find the part and get the part number. Then go back to the front page and plug the number in the appropriate box. It will tell you all the models it is used in.

    I would start with Quarry Motors (don't forget to ask for a Bimmerforums discount).

    Back in the day we used to just solder a new set of rectifier diodes into alternators. Most of the time it fixed it. BTW... are you sure it's the alternator, have you checked the charging voltage with a meter?

    EDIT:
