My 1999.5 TDI alternator clunked out.
Am I able to use a Gas VW alternator from the same year?

Wrong.BleachedBora said:Actually the pulleys are both 6-rib systems. Most of the '99s regardless of 2.0, 1.9, 1.8T or VR6 should all have 120 amp systems. If you have a 90 amp it's a rarity.

Me too... It doesn't make sense to put the 90 back in..jasonTDI said:I agree and install only 120's.
I'm curious too as to why the TDI alternator has a one way clutch.Turbine Suburban said:Forgot: Why does it have the clutch?
Thanks, I was hoping to rebuild but the pulley turns to the left just fine when I insert a screwdriver and locks to the right, the voltage regulator looks within spec:Yes. Correct. However, rebuilding them is the best option. They are not difficult to rebuild with new brushes and regulator. If the stator where the brushes ride is severe worn though, more than a mm or so, then it also needs to be replaced and that's where a junkyard one is best to rebuild. There is a thread here somewhere about how to rebuild them and links to all the OEM Bosch parts.
