Alternator Bosch or Motorcraft

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 had a car get flooded for 6 months and the Bosh alternator still worked perfectly for another 21 years. Would buy again

Fcp euro has an 100amp bosch one that works well. They have a lifetime warranty too.

Funny enough, I just did this dance today! Found a nearly new looking Bosch unit that someone had already kindly removed from the wrecker's car for me. Got it installed and tested exactly like yours though, so I'm happy.

imo take it back and grab a new Bosch from FCPEuro - https://www.fcpeuro.com/products/volvo-alternator-bosch-al157x

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

Upon retrieving the information to answer you correctly I discovered that my original alternator was a Bosch 140Amp/14Volt. My new alternator is an A-Premium 140Amp/12Volt.

I recently had two brand new Bosch remanufactured alternators fail. One after six weeks, and one was bad right out of the box.

I was driving the Mini when the engine began to struggle at idle and then shut off, refusing to restart. The starter engaged but hit a wall of resistance. After getting it home, I found the alternator was completely stuck. The one I replaced was a Bosch. Its bearing had failed catastrophically, and the pulley would not move.
