Hi guys i am new to the forum and i must say you have been a wealth of information so far. I fall into a particularly strange grey area where i bought my 2015 Ecodiesel from a used car dealer here in florida, with out fully understanding what i was getting into. You see my truck was originally sold in Canada and the AEM was done in Canada last year. The truck was sold at auction in Florida, and now i realize that FCA USA, wont honor my warranty. So far i have had to replace 2 EGT sensors A Nox sensor and a O2 sensor, all parts that should have been under warranty. My question is i now have the dreaded service def see dealer 185 miles till truck will not start but with no cel . Has anyone else had this problem, and where do i start. I have the Alfaobd and OBDLINK MX+, and was a former mechanic so i am not affraid to get dirty.
