What happens in the winter when we have temperatures down to –20 degrees C? Will the AdBlue/DEF liquid freeze?

AdBlue/DEF will freeze at approximately –11 degrees C. Volvo will offer a heating system for the AdBlue/DEF tank as standard. The starting ability will not be affected. What will happen is that the SCR catalyst will be out of function until the tank is heated up, which is taken into account in legislation, so this delay will be within the legal requirements.
