A dump truck eh? Boy, don't know, but still if it is regening daily, or more, that does not sound right. And I would get a pyro on there ASAP. You could be toasting that motor and not even realize it.

As far as the outside temp gauge, is that a reading you are getting off of the ECM or are you talking about the outside temp/thermometer to tell you the outside temp like I have hanging on the outside of my kitchen window? If it is the kitchen window one, that should have no affect on your motor, sounds like a bad probe or gauge. ECM reading, yes that can screw with your motor and something is wrong.
