And if you had a similar year VW Jetta you would scrap the car? How about any other random brand?

The charging system on this car isn't any different than most any other Euro cars ( many use a Bosch of Valeo alternator ) and in concept no different than any other car world wide.

There is no way a shop could predict a charging system failure ( or any other system for that matter ) without taking the entire car apart so don't blame them.

The the only bad decision being made here is to dump the car over a standard run of the mill repair.
