Heater booster DPF regeneration
Fuel preheating
The heater booster DPF regeneration is located at
the front right on the engine.
The coolant flowing through is heated by four
heating elements and it is then routed to the
coolant pump feed line.
To ensure that the fluidity of the diesel fuel is
retained even at low outside temperatures, a
heating element is installed for fuel preheating in
the fuel filter housing.
The fuel preheating control unit is located under the
battery box.
The fuel preheating control unit actuates the
heating element for the fuel filter heater as and
when required, and it indicates the condensation
level in the fuel filter.
The fuel heater control unit is actuated when a
request is received from the CDI control unit over
the battery sensor LIN (LIN B15) by the drivetrain
control unit, and it activates the heating element for
the fuel filter heater in the fuel filter module.

Note
The heating elements are integrated at the front of
the engine in the cooling circuit.
