This bulletin applies to 2013-2018 Ram 2500/3500/4500 vehicles equipped with a 6.7L Cummins turbo diesel engine. Customers may experience a warning light. Diagnostic trouble code (DTC) P218F (reductant no flow detected) and/or P202E (diesel exhaust fluid reductant injector performance) might be set during cold weather operation (typically when the vehicle is parked for a long time at temperatures below 12 degrees).

The remedy reportedly involves installing a thermal protective cover on the diesel exhaust fluid (DEF) injector. The DEF injector cover kit is available as P/N 68564806AA. Instructions are included with this kit.
