Thanks for replying. DEF fluid is full, all indicators are green. I did perform the regen cycle couple of times but it did not help

nope, but I was hoping to get the general idea what is the problem. Machine is new and I was thinking it most lilkely some defect sensor or something, and it should have some universal codes for them

I will. Here is what happened though. I decided to take the tractor back home from the field, and after I got the good road, I was on H4 gear, and tractor won't get RPMs more then about 1600-1700, after about 15 minutes drive on high gear, I stoped and turn off the engine and when started back up check engine light went off and tractor began to act normal, but when I took it back, same thing happen again, and won't go away now

Were you able to figure out what the problem was?

My 105p had that same problem. It was a few years old and had very little use. I read somewhere that def fluid goes bad with age. I removed the def filler neck so I could siphon the old fluid out and I replaced with a premium def. The oring did not seal properly after i put the filler neck back on with the 3 screws. I took it off again and used a form-a-gasket product to seal the unit to the def tank as I reattached it. It worked after that once i got through one or two start stop cycles. Worked for 3/4 year and i got another problem where all green lights went from 4 green to 1 green to 1 yellow to 1 red flashing and engine light flashing. Could not accelerate and only idle. I noticed the def cap was a bit loose when it was all the way on. I backed it off a bit where it felt secure. After idling a hour. 4 green lights were back engine light off and tractor works great again. Hope it lasts. I will probably buy a new def cap. Hope maybe this helps someone. If anyone has other solutions please let me know.
