Alternator Bosch or VALEO

Had the same in reverse. Bosch factory, Valeo worked fine though.

I just had to swap my alternator today on my MK7. Mine was Valeo but I could only find a Bosch locally, I decided to give it a shot and it worked just fine. Just a PSA for anyone in the same situation, they are both the same barring a slightly different orientation of the plug on the back.

I am currently leaning towards picking up a new Bosch 120 amp over the BMW.

Remember the old Bosch and Valeo alternators where the brushes were built into the regulator, which cost $15 and came off the back with two screws? Pepperidge Farm remembers.

In place of the Valeo alternator I installed a Bosch VR6 120 amp alternator with a Bosch ABA alternator pulley (its 5 ribs versus 6 ribs of the VR6).

I just went over 195,000 miles while I've driven it over 26,000 miles this year with the only failures being the original 15 year old Bosch alternator and the spark plugs needing to be replaced.

I've been looking on RockAuto. Will a Bosch remanufactured or AC Delco remanufactured work ok?

I had Valeo in my other car, very common for Bosche to overcharge.

Literally just put a FCP Bosch remanufactured 2 pin alternator in our 530 last week--it doesn't work at all. Communicating with FCP currently to send it back and get a replacement, but I'm not happy about it. I was told that Bosch was the one to go with for best quality, but now I'm skeptical.

the bosch alternators are junk. I had to warranty mine through fcp 3 times for the exact same bs: loud ass whining noise and over volting immediately after instal. Cheap chinese junk.
