I received the initial DEF notification of DEF level at 30% while traveling between Sundance WY and Hardin MT. While in Hardin, I purchased a 2.5 gal. container of API certified DEF and added it to the tru 30% while traveling between Sundance WY and Hardin MT. While in Hardin, I purchased a 2.5 gal. container of API certified DEF and added it to the truck prior to departure for Bozeman MT. The DEF level did not reset during the trip and continued to count down. I made contact with a knowledgeable friend who advised me to go to a dealer for investigation. My friend also said that it could take a number of start-run- off cycles to reset. I went grocery and pet food shopping in Bozeman (4 cycles in addition to the one for departing Hardin). While traveling to Missoula MT the DEF level was frozen at 24%. After arriving in Missoula, I contacted Demarois and got an appointment for the following morning, as they had a cancellation. Within and hour, it was determined there we no trouble codes and that the DEF level sensor was working, plus the level sensor was recalibrated. I was advised that it can take 20 starting cycles before the level resets. The charges we quite reasonable. The DEF level now shows OK. I am quite happy with service advisor Ivory and the shop diesel technician who did the work. I recommend this dealership. More
