Wife's 2005 Passat TDI (BHW) got the battery light and the Alternator Workshop notification (with the beeping).
Alternator pulley was replaced (new style) around 30K miles ago.
I have not determined whether I have the Valeo or Bosch alternator yet
but am leaning toward replacing the voltage regulator rather than the
entire alternator. The rebuilt units are VERY expensive.
Has anyone had the same problem and a voltage regulator replacement fixed the problem?
I read in the TDI 101 section that you should only replace the alternator if you have a bad bearing.
Any ideas or help is appreciated.
