Cummins Def System Gone in 2020? - New Engine?

**gpshemi** · 08-31-2017

Nothing but troubles here with my 2014.

Went into limp mode at 35k or so. Dealer had the truck nearly 3 weeks replacing all sort of DEF injection parts, only to then have those new parts eat the DEF control module somehow.

Now here I am again at 59k with DEF warnings in my MM3, but not in thw truck.sounds like a plugged DEF injection nozzle, but I'm going to run it till it blows up again, then call Ray for a permanent DEF fix. Enough screwing around. I'm not going without a truck again for 3 weeks while they fix it for the next 10-20k miles. That's crap...
