It looks like the diesel DEF problems from the earlier years are not quite ironed out in the 2016, at least in my case. Started having an intermittent CEL every 300 to 700 miles since new but the dealer I got it from would only look at it if it was active with the light on the dash. The light would go out before I got to the dealer so at about 3k miles I tried another dealer. I took it to Autonation in Bellevue, Wa. for the recent tow light control module recall and had them look at the CEL problem (it has always been a P208a code, DEF open circuit).
Shirley, as I refer to my big white van, just got back from another sleep over at the new dealer and nothing is fixed yet. But she is now a star or at least a star case. The DEF pump has been replaced (which resulted in an additional P208b code) and all the wiring checked, now we wait for the new engine control model that FCA said is the next thing to be replaced. I wish I could get some software documentation because this is the kind of electrical work I did before I retired and I get the feeling they aren't troubleshooting in a linear fashion. Oh, and the Tow Module recall isn't done either, part isn't available.
Even though it's frustrating at least it's free. I am currently betting on a bad plug crimp or ground but that is just guessing. Maybe the fourth visit will turn up some new results. I still love Shirley.
