Alternator Bosch or Motorcraft

I bought a Bosch reman for my X5 about 3 years ago, no issues whatsoever.

I'm guessing you could be Australian the labour charge would be somewhere between 120 and 150 per hour plus parts which retail close to 550 for a good quality Bosch unit so your not too far off the mark with the quote.

I have only rudimentary experience working on cars, but I got the OEM Bosch for like 300 (less core return deposit after I mailed back the old core). Took me about an hour or so to replace myself.

I only trust OEM, Denso, Valero, and Hitachi. Bosch isn't too bad.

I have one. I replaced a Bosch with it. Hasn't had an issue and had a lifetime warranty.

Yes. I had one on my e39 (M54) for a long time. Probably put close to 75k miles on it before I sold it. It was the Bosch variant. No issues with it at all. In fact, it appeared to be a Bosch reman in an Autozone box. Hard to tell what the internals were but they looked exactly the same.

13V is normal for a stock Bosch alternator. There are 14V or adjustable voltage regulator available as a replacement.

Im having the same issue with my 08 jetta 2.5, replaced the alternator and voltage regulator because the car battery wasnt charging anymore. Anyways replaced the alternator and then I had a high voltage issue with the regulator

ended up going with a Bosch remanufactured alternator. Installed it today, went super smooth, charged up the battery as I was installing it, got everything buttoned up and started it up. Battery light still on, voltage is at around 11.9 and dropping. Will randomly jump up to 14.4 volts, no correlation with revving the engine or putting a load on the electrical system.

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
