Reviews of Bosch alternator

A friend had a rebuilt bosch unit that he lent me to try and that too doesn't put out any voltage.

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

I want to replace the alternator myself, but I can't find where to get OEM parts for a reasonable price. The dealership is charging $340 for the part and the best I can find is this [Bosch alternator](https://www.amazon.com/dp/B001C64QHE/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=TXMF4LHVIWCE&coliid=IN63F3OG0M77W) on Amazon which they state is new, but it seems like all Bosch alternators are remanufactured. Why is it so damn complicated to find high-quality replacement alternators?!

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.

250,000 KM and still on the original alternator ( 1998 Audi A4 . Bosch 120 Amp Alternator ) . Had to replace a couple of bearings but that's it.

We've had all sorts of problems with Bosch reman alternators. They worked really well until Volvo put the alternator on the CAN network. The reman ones have a ton of trouble making the right charging voltage.

If you put a Botch on a Honda, it will last about 3months.

B5/5.5 alternators come from two vendors, Bosch and Valeo. I've heard they're not interchangeable because of different pulleys.

Alternators can be rebuilt. YMMV of course, but I rebuilt the Bosch alternator on my old Mk1 VW Rabbit several times (brush would wear down) with no issues.

I replaced it with a Duralast Gold. After replacing the issue still existed so I replaced the alternator with an OEM Bosch remanufactured unit.
