Bluetec AdBlue Preheater Heater
Diesel Exhaust Fluid is stored in an external tank and injected into the exhaust pipe to react with the nitrogen oxides right before the selective catalytic converter. Because it’s stored externally, however, that means that it is susceptible to the elements.
If DEF is too cold, it cannot be injected into the exhaust. To keep this from happening, DEF tanks include a special heater whose job it is to keep the fluid warm enough to stay liquid. However, like all mechanical parts, this heater can eventually burn out.
