Alternator replacement

[hahnmgh63]

Audi part # for the Alternator is 077903015R add a 'X' after the 'R' to find rebuilt which may be all that is available. The voltage regulator is 077903803A I haven't found anyone to have a cheaper price on the Regulator than Genuine, I thought that using the Bosch Part # I would be able to find it cheaper but the only cheaper ones I found were aftermarket replacements, not Bosch. Another thing, someone mentioned rebuilding the Regulator to fix bad Diodes, the Diodes are not in the Regulator but are in the other plastic housing bolted onto the back of the Alternator.

I knew you'd pull through for me Mark! Thanks!

The Diodes on mine look ok. Slightly crusty, but not bad for over 95k miles. I gave the alternator a greased lightning bath and rinse. Man did those windings brighten up!
