Battery Light Came On...Fixed For Cheap!

Some VW, Audi, Mercedes, and even some Ford models use the exact same voltage regulator; but for some reason Porsche only wants to sell you a complete alternator……..

"why make $60 when we can make $400" i believe is the reason.

I'm glad there are people out there smarter than I when it comes to these issues...I've learned a lot from these forums. I tried to cross-reference the part at Pelican, but it still didn't come up, so I ordered from a VW website. My engine got a nice detailing since it was so accessible...

Wanted to say thanks for the tip on the availability of the Voltage Regulator. Saved me a bundle on my 01 Boxster. The VW dealership had a little trouble cross-referencing the Bosch number so here is the VW number for anyone who needs it. VO38-903-803-EX. Cost me $98 in Toronto. Also regarding the removal of the alternator which can be tedious, make sure you free up the bushing at the back of the upper bolt. You will have to get to it with wd40 and wait. It needs to be backed off to give the required clearance to rotate the alternator to clear the bottom mounting. If you do that, the re and re is quite easy.

Thanks for the tip!

My alternator is acting up. The light comes on and off. I changed the old-looking serpentine belt but that didn't change anything. Now to tinker with the alternator.
