That sucks Mr. Krabs, for future reference you can rent the fan clutch removal tool at autozone for free.

Yeah, sucks big time.

RE: Looking for Valeo alternator voltage regulator assembly
The following is a continuation of this topic that I had w/ Mr. Krabs (you'll need to read bottom to top). Hope it has some helpful info:
David,
The alternator saga is over. I ended up running through the tests suggested in the link below. Testing the regulator showed that it was functioning correctly (although the test will not show if the brushes are making enough contact). But I found I had an open circuit across the two contact rings on the rotor. Never had that happen on an alternator before, but there's always a first. Anyway, I followed your lead and got one from NAPA for $200, which was less than the core charge Audi wanted. The new alternator is a Bosch (I think) vs. the original Valeo I had. I did notice that the Valeo pulley causes the belt the skew about 1/8" forward with respect to the rest of the belt train. Audi told me this when I inquired about a replacement alternator from them. They wanted $120. So while it works as-is, I do plan on changing the pulley when I do my timing belt in the next month or so. Hopefully I can get a pulley from the junkyard or maybe VW has it cheaper.
Thanks again for all you assistance. I'm going to post this conversation on the Audi forum.

Audi specifies maximum of 5mm wear. What visually looks good doesn't necessarily mean will work properly. My old regulator was exactly the same.
> What were your initial symptoms on your Audi?
Did not notice light, or gradual voltage dropping. I think it dropped and the Bat light came on at the same time, thus the alternator itself a suspect. My brushes were pretty worn, so they would have gone out sooner or later. Also, I did find a black plastic bit inside the alternator coils, that indicated to me some foreign object fell into it (one of my radiator fans had recently shattered in pieces) and caused some damage. I also noticed that the field (rotor) had poor insulation, flaking in places, this also could have been a problem.
There was one other test I did but you have to be VERY careful. I run a pinch probe to the positive output of the alternator and attached the other end to multimeter in order to measure voltage with engine running. I got 0 volts. Alternator was not outputting anything I would expect that just the worn brushes would at least output something.
> Could you take a picture of your regulator?
I do have a picture at home. Will email you.
> Did it fit correctly when you installed it?
Yes, it did fit exactly as original except I had to snip the plastic bits on the alternator plastic cover from inside, as I mentioned before. If you look at your regulator transistor, you will see several pins. The VW version has pins enclosed and has a metal piece on top in addition (heat radiator to keep it cool?).

Yeah, the reg is basically a transistor which opens and closes at certain voltages, in this case it's open > 0v < ~14v, and closes at > 14v to protect your car's electrical circuit.

Testing the regulator showed that it was functioning correctly (although the test will not show if the brushes are making enough contact). But I found I had an open circuit across the two contact rings on the rotor. Never had that happen on an alternator before, but there's always a first.

I see that is super old and I dont want to bother people who have long forgotten about this thread, but it came up during my search for the regulator so I'm gonna post it for anyone else looking. but I found the regulator here for what seems to be half the price of what the dealer wants. http://americanenginesco.com
I also found it on ebay for a lot less than the dealer. Moral- there are many ways to avoid going to the stealer.

This is the same regulator transister that's on my 2001 a4 b5 2.4L
Its option code is 8gl and the alternator # is unknown at the moment as I'm just going to replace the worn brushes.
That saves taking it out.
Theres no other part # on it except for the plastic housing #'s
I got another 120 amp alternator, its off a diesel Audi.
Model # 059 903 015g
Its regulator#s transistor # is
st U098
2542463
32208 00 47
There's a part # ink stamped onto it, I will update this info tomorrow
I don't think there's much difference between all of the regulators as long as the amps are the same.
Is this correct?
Otherwise the pullys seem to be a wide range of diameters, like only a 1/2 mm or two difference, probably other differences like ribs and position out from the alternator.
