Insite Help exhaust (SCR/DEF) service required

[Longshot]

I got all hooked up and I got back the following active error codes:
Fault Code: 3718
Aftertreatment Intake NOx - Out of Calibration

Fault Code: 3568
Aftertreatment Diesel Exhaust Fluid (DEF) Dosing Valve - Mechanical System Not Repsonding or Out of Adjustment

I assume the DEF Dosing Valve needs replacing as does the NOx sensor at the turbo.
The pump at my dealer is 800 and the NOx sensor is 600.
But not sure if it makes sense to just replace them or do a forced regen first.
Should I force regen with the DEF pump not functioning properly?

I was intending to take the truck to Mr Haggs
But I am in San Antonio - is there anyway to safely drive the truck to Atlanta with the DEF pump not functioning?
