Have you had any more issues? I had same problem but they didn't replace anything.OK, to provide feedback on my cold weather DEF issues, here's what has happened to date. Codes thrown, p20c6-00 and p208b-00 which were addressed with part # 68438682AA pump which I am told includes the heater. Second service to address service DEF system resulted in change out of hose, part # 68335685AC which is supposed to have a check valve to keep residue Def from staying in the line to freeze, based on star case approval for line replacement per Jeep engineer. So' without any single digit cold weather to test out, I hope I get a full summer and fall without a trip back to the service department for any issues. Just FYI for any of you folks still in cold country that might be having issues. Good luck!
