Reviews of OEM BMW alternator

Actively replacing our alternator now, I used this video to confirm that it was the same sound.

Dead battery within months, and car completely shutting off, your car SCREAMS alternator issue. Get it checked out.

My first car was a E46 316i, under 100tkm on odo, had it for 3 years, literally gave no problems.

Sold the E46 and got a E39 530D because I love them. Has been reliable so far, I've had it as daily for almost a year now and the only critical problems it has had are that the alternator gave out after a couple of weeks owning and EGR thermostat was bad.

I've replaced the alternator (failed on me), done waterpump & thermostat (180,000km done as a precaution).

My friend’s BMW X5 had an alternator fail at 50k, she does a lot of city driving so lots of start/stops.

This was the only non oe product in my car. When mine went it went . There weren\u2019t any bmw ones available for love nor money at the time. I get 13.8 out of mine as well. Can been fine for 12 months.

Sometimes when u replace the alternator but the battery is bad it'll just fry your new alternator.

My alternator went and I never had any lights, just weird electrical gremlins and batteries dying. Replaced it myself, took maybe 2 hours and the part was like $150 after the core return

We were on our way back from a daytrip when the M3's alternator decided to give up the ghost about 1.5 hours from home.

you dont even need ISTA to figure out the alternator is dead. A fresh and charged batter will sit at 13v, used should always be around 12v. while charging it should be 13v. the fact this is dropping while the car is running suggests a shot alternator right off the bat
