This is absolutely false they have there own heater inside the tank which thaws the urea and it only injects urea during the regen to lower NOX and under lean cruise conditions that is all periodSo with the new diesel with urea the problem is is that the truck uses the engine coolant to un thaw the urea because urea freezes at -11, the other thing is that the new engines when you start them up you have 45 mins for the urea to un thaw and start injecting or it will put the check engine light on. And when it's just idling it prob doesn't get hot enough
