At 151 hours, tractor started to flash code 81 F11 with 1Hz blinking amber. According to the list of codes I got from the dealer, this is Fault Code: P242F DPF Regeneration error. I haven't observed any change in how the machine operates, so wonder if it was a momentary false positive that is now lodged in ECU memory. The tractor is still under warranty but I am several hours from the dealer and don't have a means to transport it. I haven't found a way to force a regen cycle, and I tried disconnecting the battery as suggested in some other threads but that had no effect. Has anyone ever managed to do a DIY fault code reset on these machines? - Tim
