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.

Pros: worked just fine, compatible

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).

Pros: increased amperage

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.

Pros: motor itself is reliable
Cons: alternator needed replacement
Mileage: 313821 km

I can\u2019t make out the sound but once upgraded the alternator on my 29 roadster pu that had a late model bronco v6 in it and the darn thing sounded like I had a super charger with the whirling. Crazy sound but ran perfectly fine for as long as I had the truck (years).

Pros: ran perfectly fine
Cons: sounded like super charger
Vehicle: Ford Bronco

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.

Cons: doesn't work at all
Vehicle: BMW
