I ended up getting a new one from BMW after two remans failed with once catastrophically failing and catching fire almost burning up my car.

Paid $1,214 out the door. Alternator... No experience with cars and don\u2019t feel comfortable installing myself. Based off local availability, I can\u2019t imagine an option I would\u2019ve been happier with. Of course it\u2019s overpriced, but I can justify the spend based off how seamless the experience was.
Had the same issue a few months back. Put in a new alternator and it’s been perfect since.
You need to try using a OEM REMAN or OEM NEW alternator. Aftermarket items can really affect BSD.
My 540i at 141k started eating me alive, Alternator blew up
