If you removed the filter and didn't bypass the SCR box, soot and/or coolant can contaminate the coating on it. If it's bad enough, it will throw low quality DEF codes and 5mph derate since it can't reduce outlet NOx levels enough. Check with some of the DPF cleaning places to see if they can service the SCR box. I'm not sure if it would work, but I would try it before dropping 4k on a new one.
Should I un delete my rig?
