One problem related to alternator/generator/regulator has been reported for the 1999 Volkswagen Passat. The most recently reported issues are listed below.
Shortly after bought car, had many makeup problems: trim panel falling off, 3 our 4 windows have been fixed numerous times. Cannot have trim fixed unless do whole car, which is too expensive and I didnt pay all that money for a car to have dish out more money for something that should not happen. I have paid to have all the windows fixed except this last time, I just will not do it. No accidents, nothing for these problems to be occuring. Also, the tie rods have been replaced numerous times. Lastly, steering/suspension has been a problem. All these problems took place four months after purchase and since then has been a problem.
