The most expensive one at Rock is a Bosch for $186.79+ core.
Mine went out at like 105k swapped out a Bosch immediately but if not always go with denso.
Well I definitely wouldn't have gone aftermarket but I understand you might have been in a pickle

As far as why it's not working at all, you need very good clean connections including good ground connections everywhere
Bosch is a OE supplier to BMW - I would choose that over Valeo if it were a choice I needed to make.
I installed a new BOSCH alternator in my MERCEDES-BENZ 190E 2.0 1991, and unlike the old one, this one has a **D+ port, a B+ port 1, and a B+ port 2.**
This is a known issue with non OEM and especially bosch alternators, the regulator gives a different signal to the power control unit.
I have replaced my alternator with a good "?" Bosch alternator and it charged for 3 days but now the battery light is on until the motor is above 2500 rpm
The voltage regulator on the alternator is bad.
Everything went well, or so we thought, as he turned on the car it started to slowly smoke. I assume that the ac compressor plug got shorted or was loosely plug bc it was the hardest thing to replug and the fact the ac isn’t blowing cold air anymore. We recharged the battery to 12.4-12.5 v. The alternator was only pulling 13.3-13.7 v with load and without load. Mind you this was a new OES Bosch alternator.
I bought a remanufactured alternator from Autozone and it did not work. I then bought an amazon alternator. It went out 2 weeks later. I then bought the OEM Nissan alternator. I've not had a problem since (6 months)
