AdBlue Heater

The AdBlue heater warms the tank, pump and lines because AdBlue freezes at about minus 11 degrees Celsius.

What is AdBlue Heater?

It thaws frozen fluid after a cold start so dosing can begin. The heater is often built into the tank pump and sensor module. Freezing itself does not damage AdBlue; it works normally after thawing. Parking in a garage can help in very cold weather.

How it works

Electric heating elements warm the fluid in the tank and heated lines carry it to the injector.

Why it matters for your car

Heater faults often require replacing the whole tank module. Take dashboard countdown warnings seriously and have the system checked in time.
