Alternator Bosch or OEM Volvo

I’m running my a 120amp Bosch but my car is m42 it’s honestly overkill for my setup with aftermarket speakers, amp, and sub.

bosch alternator is better. get a bosch alternator.

Rockauto.com shows reman units, both Bosch and Valeo. As far as interchange with Bosch, I dont know, but worked at the dealer and they always asked if it was Bosch or Veleo because it could not be determined by Vin.

I managed to get a reman Bosch 150a/140a last year from Advance Auto for around $190.

I just replaced the one in my daughter's Mk 4 with a rebuilt 120A Bosch one from Rock Auto last week.

I would go Bosch if I had the option. Mine went out on a road trip. I had to go with what option was available at the auto store I was able to limp to. Lucky there was one close by but it was who knows what brand. It was my only option so I bought it. Probably duralast or something but it’s working 2 years later.

I have a 100A alt from a 900 series and it keeps me powered, but barely. And if I have the stereo loud + headlights and fogs and a/c, I get belt squeal.

The alternator went out on it, and I had to replace it four times due to faulty over the counter rebuilt Bosch parts.

I had a Bosch alternator die in <6 months. Got installed in November 2024 and it died a few weeks ago.

I picked up a 07 jetta 2.5 from the auction for a good deal and only 95k on it. The problem is the battery is not charging, figured ok needs new alternator put a bosch unit in and it is still not charging the battery. Put multi meter to the post on alternator and it is only putting off 11.5v.
