Crystallization Check: Before replacing, check if the nozzle is simply plugged with white "DEF rocks." Sometimes these can be cleaned with warm distilled water, but if the internal solenoid has failed, the whole unit must be replaced. No Core Charge: Unlike many heavy-duty injectors, the "New" version of this part (2888173) typically does not carry a core charge, though the "NX" (Reman) version might.
