Sitting in the waiting room now. SES light came on a few days before a Previously scheduled vehicle check.
Technician tells me the car is in need of some programming related to the EGR valve and DEF system. Tells me that if the issue recurs the replacement of the valve is our next step.
I'll update once I see their work ticket if there's anything of note.
Edit: keeping the car overnight. Will know more tomorrow.
