Alternator AC DELCO or OEM BMW

Alternators don\u2019t exist so you\u2019ll be using aftermarket brands like AC Delco unless you can find a rebuilt Denso.

For the price difference just get ACdelco they’re a reliable brand that doesn’t create shit and will stand behind a warranty.

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

I had beefed up my audio system and the stock alternator could no longer keep up with the amperage demand. I decided to upgrade it myself. Eventually that unit gave 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.

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

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.

Its a total crapshoot anymore. I had an ac delco gold series last maybe 800 miles before it almost caught fire. Yet in the past I've had em last years and 100k+...

I used ACDelco on my Hyundai Santa Fe and only lasted 8 months before almost leaving me stranded. Also noticed that aftermarket alternators lugs my engine especially during high output while original genuine alternators do not.

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