Yes, VW had tons of surplus cash to throw around to build a factory (and they've started in Mexico), but VW doesn't directly control Audi, like GM does with Cadillac or Honda does with Acura. All of the brands under the VAG umbrella have their own upper management and board. Not a centralized one like GM. This basically means that VW doesn't have too much say in Audi (or Porsche), they run themselves.

Of course, ultimately, big projects like a factory have to be green lighted by the central VAG management.
