I agree that VW did the right thing. They realized there was a flaw in their product, and corrected it as it should be, rather than waiting for someone else to make a big deal out of it.
I'm not suprised. The few 2011s I've worked with do seem to have a LOT of multiplexed wires. I'm just suprised it didn't get caught before production. Seems like something they would test. Or maybe at least would have found when the dealer was taking delivery and they sounded the horn before backing.
