Regarding the vw alternator warning problem. I experienced the same thing a couple of years ago. The warning light came on so I took the car to a serviceman (not a vw dealer). He said the alternator was putting out the necessary current and the battery was being charged properly. The problem was a diode that was leaky. The diode was in the circuitry of the warning light system. Therefore it was not an alternator problem to be concerned with. The light has come on only a couple of times in 2 years and remained on for only a few minutes.
