Does your truck have DEF.

 

Yes. I've never let it run out or too low.

 

did you recently let the DEF red light come on when it got low.

 

Sad face. Not looking good if that's the case.

I could use the miles of another east coast run, given that I've been sitting for 10 days here, but I've really got things I have to do at home.

 

Not recently but it's happened to me a time or two in the past. The light in mine will start to come on at about 1/8 to 1/4 tank, according to the guage itself.

 

I was having some of the same problems.A mechanic told me,never run it under 3/8ths of a tank.It crystallizes in the tank and starts to gum crap up.So Ive been keeping it fuller and havent had any problems.Could be a coincidence.There is just to much computer crap on these trucks.Glad Im going local.

 

I won't run it that low ever again, after the fiasco I've had these past several weeks.

There were fibrous materials, like a shop rag, jamming up some filter in the def system. I don't understand how it got in there, but hopefully that was the last problem.
