WARNING: This page is about a different variant/trim than selected.
The Diesel Exhaust Fluid (DEF) line provides hydraulic connection between the DEF injection pump and the DEF injector. The DEF line is manufactured from a plastic material, which is specifically designed for use with DEF.
A copper based resistor wire is installed within the DEF line with an electrical connector. The resistor wire enables electrical heating of the DEF at low-ambient temperatures.
The DEF line has hardwired connections from the DEF heater control unit.
