AdBlue / DEF Urea Heater Repair Kit — Mercedes-Benz GL X164 3.0L | OEM 1644711275 / 1644710975

Fix the AdBlue Urea Heater on Your Mercedes GL X164 — Repair Kit Prevents Freezing Faults.

The AdBlue (DEF) urea injection system on the Mercedes GL X164 3.0L diesel uses an electric heater to prevent the urea solution from freezing. When the heater fails, the system cannot inject DEF — triggering AdBlue warning lights, fault codes, and eventually restricting engine power. This repair kit rebuilds the heater assembly.
