I eventually took it to the dealer (I know...) and they diagnosed it as a bad DEF pump unit. It was replaced under warranty (Yay!). But, according to Quickserve it could be a malfunctioning diesel exhaust fluid (DEF) dosing system, exhaust system leaks, a malfunctioning SCR catalyst, degraded, diluted, or incorrect DEF, diesel exhaust fluid deposits in decomposition tube.

Thank you so much
