VALEO › Voltage regulator

Electrical behavior:

I just had this problem with my daily R, it has 141,000 miles and the battery light came on. The alternator really isn't that hard to remove so I just took it off. My issue was the brushes in the regulator were worn out. I bought some new brushes; I bought 2 sets for $11. Fairly easy job, just google Valeo alternator voltage regulator brush replacement and you get a few DIY videos. BTW my slip rings looked almost new, no grooves at all.

Pros: easy job, slip rings new

Cons: brushes worn out

Electrical behavior:

I ordered a Valeo voltage regulator, which comes with new brushes, from an eBay seller for $35. I read 14.48 volts at the battery with the car running so initial indications are that the repair was a success.

Pros: repair was a success

Electrical behavior:

Took alt off and reinstalled vReg. Reinstalled, was perfect kicking to 13-14V!.... *except* low & dropping V when idling for some minutes (9.5-11.5V). Noticed while staring @V through the climate control it hit 14.3 a couple of times. Hadn't been that high since \"repair\". Was conscious of it, thank goodness, because it proceeded to overcharge up to 17V!

Pros: perfect kicking to 13-14V

Cons: low & dropping V

Vehicle: Audi TT
