I got BOSCH AL113M from Adv auto (with a code cost me about 80), then went to tractor supply and got several large washers. I took the pulley off my old alt and put it on the new long-nose alt, stacking washers until it lined up.

So my just-installed today reman Bosch SR33X turns the light off with a very slight blip to 1200rpm.
The tech who replaced my alternator (@10K mi) left his permanent fingerprints on my hood...have to try to buff it out. Apart from the bad alternator documented in another thread (hopefully a one-off), the car has been great (especially in winter) - no leaks, no sunroof issues, buzzing, rattling, vibrations, etc.
I went with the cheaper Bosch unit myself for my M3, and it's been working well for the past 4k miles.
If the belt was melted to the alternator pulley, there was enough friction to melt the rubber. Simple answer, replace the alternator.
Also, my 90A Bosch alternator is about the same size and weight as my old 65A Bosch alternator. Going to a 90A alternator is a great cheap mod.
I did this on my mk1, along with a 90A Bosch alternator (AL49X ?) and a variable voltage regulator to get 14V. Also, I replaced all the tail lights and side markers bulbs with LED bulbs (superbrightleds) . This greatly reduced the amps drawn from the alternator.
Bosch rebuilt alternators are like $175 online. Lots of people experienced low quality rebuilts. Have people had good luck with Bosch rebuilts?
I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.
I had one during college... For a V6 it wasn't particularly quick and handled a lot bigger than it was. In three years it ate five alternators and the intake runner control box was notorious for failing (killing what little power it had).
