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 went and got a Mazda one off of Moss bc I was sick of AutoZone remanned ones blowing up. It's plenty nice for stock electrical load
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.
If anyone is curious, the 120a Bosch and Valeo alternators (rectangle ground connection) are completely interchangeable despite the statements online saying they have different pullies and mounting points. They are slightly different but everything lines/bolts up the same. The Bosch (left) is a decent amount larger in size, not sure why, but it fits perfectly with no clearance issues.
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 used to have an alternator that required me to rev to 5k before the light would go out! My current one needs a slight blip to 1200 to make the light go out. I just ordered a new Bosch rebuilt alternator to replace.
Symptoms: Flickering lights, and occasional hiccup start. Now battery light is coming on and staying on. When stationary battery tests around 12.5 volts. When running, that drops to 11.7 volts.
On my '93 240, I used a 740 external regulator Bocsh alternator...100amps...the problem is is that the voltage regulator takes a dump, which leads to people replacing the entire unit (like me years ago).
