Alternator OEM Audi or Bosch

Bosch is the OE manufacturer for motorcraft alternators so if you find a Bosch chealt cheaper, go for it. They're the same minus the motorcraft sticker.

That Bosch VR6 alternator was not a direct fit, but significantly easier than the Delcos other Rover owners commonly used. My method was faster, cheaper and way more reliable.

Get a Bosch or Denso alternator. I'd buy used before one of those brands. Just my preference, I know they sell tons of starters and alternators, but I don't like to do things twice.

Update: There was a direct short in the alternator and when it shorted internally it also took out the 200 amp protection fuse ($115) too for the battery. I got a new Bosch unit and I was happy to find out I did not have to bring it to the nearest dealership and that a local German repair shop were able to do it.

The 07K 2.5l came with either a 140A Valeo or 140A Bosch alternator. Be sure you're buying based on alternator brand.

I recently purchased a 120 amp (refurbished) Bosch alternator at Advance Auto and kept the receipt. My original 90 amp alternator lasted 14 years before it stopped charging battery.

I wasn't crazy with the AC Delco (GM) alternator conversion when I used it on my MGB engine. The Bosch ones seemed to be a little better designed and easier to convert, plus they looked simmilar to the Lucas ones.

Bosch rebuilt alternators are like $175 online. Lots of people experienced low quality rebuilts. Have people had good luck with Bosch rebuilts?

So I bought a new alternator off of Rock Auto that I was amazed that I had to re-use my old pulley? But when I went to put the pulley on, the nut stripped on the new alternator like instantly. The whole ordeal is trash

Good thing you got a Bosch instead of the duralast. I had a duralast alternator last about 2 weeks and when I was standing in line at AutoZone to return it and buy a real alternator, there was someone behind me also holding an alternator that lasted two weeks.
