Alternator OEM Audi or Bosch

Bosch makes (made) excellent rebuilt alternators and I’d check them out.

I bought a Bosch alternator at O’Reilly’s for ~ $300 and the gaskets at Autozone for ~ $100 (you can get them cheaper but I needed them quickly)

I would use the BOSCH from fcpeuro.com without hesitation.

I replaced my alternator two years ago, and I put in a Bosch, and I haven't looked back. It works great and also has a warranty.

I had my alternator go out on me at 165,000 KM on my audi S3 2015, got a rebuild for half the price of a brand new one and since it's a rebuild the warranty on it is for 2 years. Paid roughly 500 bucks and 100 for labor.

Best has been new Bosch or Delco-Romy from jobber stores. Never had one of those fail yet.

Rs6 definitely has an alternator issue. I’m currently at 25k on oem alternator.

It went out at 40,000 miles and was replaced without issue by the dealer which provided an A6 as a loaner for the week it took to replace the alternator. I still love the car and would not move to Mercedes

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

My vehicle had this issue and they said it was because there was a bad batch of batteries in some of the models which was causing the alternator to fail. I had several issues with this vehicle around 50k miles such as failed alternator which was replaced because of the warranty but this should be a recall!!! Very dangerous and unreliable.
