Are you talking about the engine warning light on the dash directly under the glow plug light that was flashing? If so, was it flashing by itself or was there also a light (DPF) on the upper right of the dash flashing at the same time?
1) If the light was on or flashing by itself it will need a trip back to the dealer.
2) If the light was on or flashing with the DPF light or lights flashing the soot level is 100-140% and the DPF was regenerating. In this condition the engine is derated to 50% and RPM is limited to 1800 until regeneration is complete. All work with machine must stop until regen is complete. Then engine would return to normal operation and RPM.
What you describe happening sounds like #2 condition which is normal.
I'm sooooooo glad I have a tier 3 tractor !!!!
