Alternator Bosch or OEM Volvo

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.

If you were family or my customer I would get the Bosch.

IMO a rebuilt German Bosch unit is far superior to the Chinese alts.

I'm swapping my 90a Valeo alternator for a remanufactured Bosch one. (Which actually says Valeo on it but has a Bosch part number and came in a Bosch box.)

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

Don\u2019t get a Bosch

I replaced the Alternator on my 2016 Mini Cooper Paceman with a brand new Bosch Alternator. For whatever reason the Alternator is only putting out 11-11.6 volts.
