I am aware that my alternator has been making noise for a month now and I can push it no longer since it decided to start dropping voltage yesterday on the freeway. So I was wondering if there is a kit I can buy to rebuild it or (have it re-built). or should I just go buy a reman? I have not pulled if off yet so I dont know which I have at the moment either. I did some searching but I couldn't really find what I was looking for.

thanks.

I wrote a DIY about replacing the brushes on the Valeo units here: http://www.audizine.com/forum/showthread.php/358309-DIY-5-Alternator-Fix-replacing-brushes-%28Valeo%29

Anything further than that (bearing replacement, diode replacement, etc) requires desoldering some very high temp solder - not something that's very DIY friendly. In that case, I suggest you get an OEM Audi alternator from a junkyard for ~$35, throw in some new brushes and call it done. A quality reman alternator is another option, but that is a lot more expensive.
