I can confirm that the factory voltage regulator in my 2000 Boxster S, 6-speed manual is Bosch part number F 00M 145 225 . As mentioned previously, Porsche does not sell the voltage regulator separately. This is a standard part used by Audi, Mercedes, Porsche, and VW.
The following Bosch part numbers are cross-referenced by a seller on ebay selling the factory bosch part:
BOSCH F-00M-145-200, F-00M-145-209, F-00M-145-225, F-00M-145-350
That seller also cross-references the equivalent VW part numbers:
VOLKSWAGEN 038-903-803, 038-903-803B, 038-903-803E, 038-903-803EX
My experience: On my way home from work one night, the headlights started to go dim. Then they dimmed more. Then my dash lights dimmed. Then the ABS and battery lights started freaking out, and finally the car died. I was able to jump it and limp home. I pulled the alternator and took it to Pep Boys to test it (Kragen and Autozone couldn't on their machine).
Test Results:
Lamp/Diode Trio test FAILED
Regulator test FAILED
Rectifier test PASSED
I ordered an aftermarket replacement voltage regulator on ebay for $40. I installed it and went back to Pep Boys to retest the alternator. It passed with flying colors, so I reinstalled the alternator in the car and all was good for about 4 months. Now I'm seeing intermittent slight flickering map and dash lights. Also, I can light up the battery light very briefly at high rpm when I get on the gas. Otherwise, the car runs and seems to charge fine, but I suspect my cheap aftermarket VR is going out after just a few months. The moral: spend the extra bucks for the bosch part. Way cheaper than needlessly replacing the whole alternator.
