Check Engine - DEF problems

FYI - Chrysler re-released the CAT replacement TSB yesterday (9/24) as 18-064-15. Same replacement part number for the CAT, but no testing of the DEF injectors or tank as with the procedure in 18-045-14. Also, it is now officially an RRT (15-093). So at least that's some more formal acknowledgement that it is an issue that likely affects all 2014s. Not a full blown recall, but you should be able to get a replacement quicker without haggling with the dealer. Probably worth having them check your VIN for eligibility next time you're in the shop.
thanks for posting this information. I have been having problems with my 2014 - in and out of shops several times before just recently the folks at Wilder Auto Center in Port Angeles, Washington, finally decided that my SCR system needed to be replaced (after I contacted Jeep directly and opened a case). this was Wilder's first experience with this repair. they were very good to work with. I have driven the jeep about 100 miles since getting it back and so far no problems. upon picking it up I immediately drove for an hour at highway speed to break in the new SCR and this was after the service tech performed a "force Regen" so the SCR was well "burnt in". hope this cures my MIL light problem. I do love driving this vehicle. where do you find these TSB's ?
