I had the same problem with the DPF except it would run through the cycle when it didn't need too, and wouldn't stop. And I would have no power, I only had 15 hrs on it when it started to do this, and it would do it when it was cold outside! Below zero. I sent mine back they put in a warmer thermostat, and they adjusted a valve. Haven't had no trouble. But it's warmer outside, time will tell. I don't get why they put dpf on a tractor, I had a Deere a 2010, 3032 it didn't have that, and never had any trouble with it. Can someone tell me what the purpose of putting this on a tractor is, I don't get it.
