MERRY CHRISTMAS! HAVE TO BUY AN ALTERNATOR FOR 95 S6--WHERE'S A GOOD PLACE??
One in Gmbh for like $725.
Any other alternatives? Reman failed after 8000 miles.
Thanks & Happy Holidays--Tom

And Merry Christmas to you.
I forgot to suggest GVAP for OE parts:
genuinevwaudiparts.com
And specifically for the 046903015FX
Audi Parts - genuinevwaudiparts.com
and for the 054903015FX the same source shows NLA

Etka is showing Bosch or Valeo choices. Valeo is a 90 amp and shouldn't be on your S6. But I show 2 Bosch choices and both are 120 amp units. The 078-903-015-C also called part number OE part number 078-903-015-F or FX appears to be for the AFC V6 engine. The S6 on the other hand uses 054-903-015-k for up to 8-95, and after 8-95 uses 046-903-015-f, the strange thing is the OE p/n alternator on either production date vehicle is 046-903-015-F or FX (FX means reman part as opposed to just F which means brand new parts). I can't get either one but wanted to give you this information as I see it to help you make sure you get the right one for your car by using part numbers to cross whatever it is you end up buying.

I have revised them as below

That said, alternators can be rebuilt, often locally.
EVEN MORE IMPORTANT, what about the voltage regulator? They go bad and can fairly easily be replaced:
028903803D (or DX) is the regulator for the "18" alternator, i.e. 054903015FX
and 028903803E is the regulator for the "19" alternator. i.e. 046903015FX
