Good To Know

Q: What is a common cause of DEF pump failure? A: Contamination of the DEF fluid, crystallizing urea deposit buildup, or operating the system in freezing conditions without adequate heating can cause pump failure.

Q: Does this replacement pump require software programming? A: While the pump itself is a mechanical and electrical plug-and-play unit, clearing active emission codes and resetting the system often requires a professional diagnostic scan tool.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
