Why does my AWD not engage?

What is your question?

My Anti-skid Control light came on, which means the system is OFF. Pushing the switch to re-activate the ASC system, does nothing. I don't know if the two problems are related, but I no longer seem to have AWD. Got high-centered on snow, and only the front wheels were turning, not the rear wheels.

What makes this problem better or worse?

Nothing

How long has your 2015 Volkswagen Tiguan had this problem?

The ASC light came on for the first time about a week ago.
