Action in service

Consequential faults: If additional faults for the following components are entered, rectify these faults first:

• Monitoring voltage (5 V) of sensors and actuators (supply 1): The voltage is outside of the valid range or is too high or too low (short circuit to B+ or ground).

Check the air intake duct and intake plenum for tightness.

Check lines and plug connections between the following components:

• DME
• Charging pressure sensor

Replace charging pressure sensor.
