I would think this wouldn't be the hill they would like to die upon but apparently being right is better than maintaining the relationship.
Fine then; you may have the hill. Considering how Volkswagen has treated their customers and engineers I'm not surprised anymore by how I've been treated.
I've also noticed they haven't sent a customer survey. Color me surprised. After asking me for all fives every other trip apparently they would rather disown me rather than face unpleasant results.
