Yes, AdBlue can freeze when exposed to very low temperatures. Its freezing point is around -11 °C.
This might seem concerning, but vehicles originally equipped with an SCR system are designed with this characteristic in mind.
Therefore, the fact that AdBlue can freeze does not mean that a vehicle automatically becomes unusable as soon as temperatures drop significantly.
Modern systems generally have solutions to manage operation in winter conditions.
However, it is important to follow the vehicle manufacturer's recommendations regarding the use and storage of AdBlue.
If you keep a container, keep it properly sealed and under the conditions specified by its manufacturer.
Also, avoid trying to modify the product yourself by adding water or another liquid to prevent it from freezing.
AdBlue must retain its intended characteristics to function correctly with the SCR system.
