vs
Alternator Mitsuboshi or OEM BMW
Reviews
Actively replacing our alternator now, I used this video to confirm that it was the same sound.
Vehicle:
BMW
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.
Pros: reliable, no critical problems
Cons: alternator gave out, EGR thermostat bad
Vehicle:
BMW
Mileage: 100000 km
I've replaced the alternator (failed on me), done waterpump & thermostat (180,000km done as a precaution).
Pros: done as a precaution
Cons: alternator failed
Vehicle:
BMW
Mileage: 190000 km
I would go for the Pure Energy new Mistubishi that is 190amps for 200 bucks.
hope you got her fixed up... had a similar issues pulled my alt and gave her a deep CLEAN and working again but ordered this up [https://www.amazon.com/dp/B00M01GQ3C?ref=ppx\\_yo2ov\\_dt\\_b\\_fed\\_asin\\_title](https://www.amazon.com/dp/B00M01GQ3C?ref=ppx_yo2ov_dt_b_fed_asin_title) exact part number from mitsu cross referenced. EXACT FIT AND WORKS LIKE A CHAMP now to have the OEM rebuilt and have it as a spare
Pros: exact fit, works great

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.
Pros: fine for 12 months
Cons: non oe product
I have one with 44k miles sitting in the garage right now with a bad TPS and an oil leak.
The last drive down the street saw me with a dead alternator and blown alternator fuse. Replacing those two resulted in the above surprises afterwards.
Even replacing the alternator is a half day knuckle busting job assuming you know what you are doing.
Cons: bad TPS, oil leak

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

Pros: genuine parts
Cons: nag oovercharge yung battery
