This won't last long. China is the pits for quality. VW has plants in the US they can ramp up.
VW has factories in Mexico, where beetles and some golf's are assembled. Conincidence that those two models also has one of the most problematic vehicles.
Passats B5/6 and Audi A4 (B5) use to share the same platform and hence assembled in Ingolstadt, Germany. Since then, the newest Passats share platforms with the Jetta, and I forget where they are assembled (though I think it's in the states or mexico).
