    I would look at the tag on the alternator in your

    car and ask for the exact same part number as a replacement. I don't have any knowledge of the rebuilders, just get one with a national warranty.

    Thanks Mark,

    Any real differences in manufacturers of these rebuilt units? I don't even know what is in our cars but I assume a Bosch unit.

    Will ANY unit I find work just fine or should I REALLY stick to a BMW brand name? Advanced Auto Parts has one made by Worldwide but they said it was an exact fit.

    Regards,

    I wouldn't head out on a 1000 mile trip with your

    current alternator. I'd replace it before you leave. Most any auto electrical shop should be able to get you a rebuilt in a couple of days.

    That is an indication of bad diodes in the

    rectifier circuit in the alternator. Id start checking around for a rebuilt alternator.

    Battery idiot light is on with key out / car off

    Well this is a new one on me... getting out of the car and notice the red battery light is still lit on the dash. Is this a "normal" indication of something wrong (or an abnormal one;-)

    Any help is appreciated. It has been on for at least an hour now
