I was gonna order the TMS pulleys so I went to check which alternator I have but I don't see any markings. Any ideas how to tell if it's Bosch or Valeo?
edit: I figured it out

Looks like Bosch but there's a comparison pic here:

Yeah, I have the same one. It was tricky to find these stupid markings without taking the alternator off
Thanks for that heads up about the 330 specific alternator, I think I'll just call them tomorrow and order over the phone so there are no mistakes. How do you like those pulleys? You got the underdrive alternator pulley, not the lightweight one?

I got the underdrive pulleys. Really couldn't tell much difference at all, except the engine maybe seemed to breathe easier, meaning there was slightly less effort when it started to pull when you got on it some. For me, it wasn't noticeable enough to make the change if I had to do it over, but it didn't hurt and I needed new belts anyway.

HEY, Listen! I'm fighting this battle myself. That's the same alternator that I've got, but I didn't notice the plug until I had a replacement Bosch 120amp unit already bolted in.
They both have the same "0 124 515 105" P/N stamped on them. Both Bosch. Both 120amps. I'm convinced the alternator is the same, but the Voltage Regulator is different (and therefore the connector is different).
Some of us seem to be afflicted by some franken-setup that has a wiring harness from '03-'04 Z4s. Here's the RealOEM Diagram for the CORRECT voltage regulator and here's the CORRECT alternator (also listed for our cars as seen here).
Correct P/Ns:
Alternator: 12317519620
Voltage Regulator: 12317515319
Effectivity for the voltage regulator is supposedly:
525i E60 M54 2004 - 2005
530i E60 M54 2004 - 2005
Z4 2.5i Roadster E85 M54 2003 - 2005
Z4 3.0i Roadster E85 M54 2003 - 2005
Check this out:
Both alternators:
My original alternator/voltage regulator with oval plug:
New alternator with square plug:
Now, I bought all this stuff from ECSTuning, and am about to give them a call to see if they can sort things out for me here. Their site says that this replacement alternator works with all E46 330i/ci models, and it obviously doesn't.
Check this out:
This is the 120Amp Bosch that fits "all" E46s and that they said would drop right in (and that I bought). Note the square connector:
This is the 120Amp Bosch that also fits "all" E46s, and happens to be the one that came out of my car. Note the oval connector:
So...just a heads up:
*****Check that voltage regulator select plug before you buy a new alternator!*****
