I have a 2012 f-350 with 1100 miles. when should the DPF start the regeneration process? I have barely noticed a screen on the display, when driving, saying "cleaning DPF" then ok. Then changes back to previous screen. Is it cleaning? Or do you have to press the ok button to start it? I've had many diesels but none w/DPF systems.
