6.7lt EGR permanent defect. Chrysler never acknowledged the problem

Is it something I can fix?

Problem just occurred today with new batteries.

Truck always vibrates a little, but gets much worse when pulling. Power loss could be separate issue.

Does the line i

alot of greas on wheel. i figure its a seal.

3 accelerator pumps with key on didn't work for me. Do I have to have message board on certain display or something?
Don't want to take back to dealer for just this if its simple. Alos they changed the oild and didn't reset it like the dummies they have been. They also won't re-cal. my speedo for 19.5" tires.

the trailer brakes work. and the wiring has been checked. but when trailer is hooked up. the truck dings all the time. and the message center say's ( check trailer brakes wiring).

i checked to see if they were tight. and i could turn them in a bunch more.
