N33/7 Control unit of condensation sensor for fuel filter with heating element

Location

The control unit for condensation sensor for fuel filter with heating element is located in the engine compartment at the rear right.

Task

The condensate control unit actuates the condensation sensor for fuel filter with heating element (B76/1). The condensation level is read in by the control unit for condensation sensor for fuel filter and transmitted to the CDI control unit (N3/9).

Input and output signals

The following input signals are evaluated by the control unit for condensation sensor for fuel filter with heating element and issues appropriate output signals:

Direct input signals

Direct output signals

Direct input signals

- Circuit 15

- Terminal 30

- Condensation level from the condensation sensor for fuel filter with heating element

Direct output signals

- Fuel preheating system heating element

- Condensation level to CDI control unit

Function

For an outside air temperature <2 °C the control unit for the condensation sensor is switched on and actuates the heating element in the condensation sensor for fuel filter. The control unit for condensation sensor switches off after 30 minutes.
