Electro-mechanical power steering assist failure light and no power steering on 2009 Volkswagen Passat

The power was out in this car for a long time. I have that light on my dash plus an airbag light. Everything else has corrected itself less those two lights and no power to the steering. I assume it is a module, but which one and where is it? Any suggestions are welcome.

These problems are occur even with a battery change. A VAG (VW factory) scanner needs to reset troble codes.
