[s-cars] Voltage Regulator P/N

[Tom Green]

Eugene,
I have Bosch P/N 1 197 311 511 on one alternator and Bosch P/N 1 197  
311 214
on the other, both 120 Amp alternators. Neither had a Audi P/N  
although I believe
both are original.
  I had a spare rebuilt locally and the shop used a non-Bosch  
regulator at $29
instead of the $59 Bosch part.  That means asian rim country of  
manufacture,
but it had no P/N.  It works fine in short-term (2 months) , so I  
would look for form
factor more than part number, since the function performed for a  
14-14.4V system
are the same.
Or simply, if it will fit, it will work.
How much is the regulator?

What is the condition of the original voltage regulator?  Does it  
still have brush
material left?  Was the alternator making any noise?  I'm prompted to  
ask how
you know the alternator is the problem because they are reliable  
units, including
the voltage regulator.  Of course, with the labor already expended to  
remove/replace
the alternator, you don't want to reinstall anything questionable.
