Alternator Bosch or Mitsuboshi

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

I bought a brand new, OEM Bosch alternator from Rock Auto. A week back I started noticing a bearing squeak sound in the engine on startup... Later got another battery light... Today was driving and lost power steering suddenly and got battery light again. Pulled over as the car was getting hot quickly. Opened the hood and the serpentine belt was shredded. Alternator was completely seized and had burnt belt on the pulley. Got it towed home.

I had a bosch alternator in my Mark 2.. 8valve motor. I noticed the battery was not being charged. so instead of dealing with the voltage regulator or brushes etc, b/c the unit was old I decided to go with a brand new one. making me think i should have ponied up to the Bosch.
