Anyone that has had an alterantor go bad on their bmw

[Crowz]

This isn't about an X5 aka E53 but instead is about my daughters 1997 528i aka E39. Since our X5's share a ton with the E39 I was wondering if our X5's could do this.

My daughter called me today saying the car was acting strange.

She was leaving out to go shopping and at first the car turned off the headlights.

Then a bit further the radio.

Then as she was almost home the dash lights.

Then everything else but the motor right before she got home.

She made it home safely. Basically the car was turning off things to keep running to get her home. AMAZED.

I have never had an alternator go bad on a bmw so I am wondering which models can do this. Any ideas?
