I think he talks about 0 Starts, SCR AdBlue Reset. It is the famous shut down scenario. I was researching this for a while but gave up because of no time. Codes are:
4D08 SCR System, warning and deactivation scenario: Warning Stage ( Maximum Range Reached )
41F9 SCR System : System Error and poor urea/water mixture quality detected
474C SCR System : warning and deactivation scenario: Warning level 1
4748 SCR System : warning and deactivation scenario: Warning level 2
4746 SCR System : warning and deactivation scenario: Warning level 3 ( Maximum Range Reached)
