Action in service
Consequential faults: If one of the following fault code entries present, eliminate this fault code entry first: 0x1F1A91, 0x1F1A96, 0x1F1A97, 0x1F1A98 (monitoring 5 V voltage supply of the sensors/actuators, supply 2: voltage too high) or 0x1F1A93 (monitoring 5 V voltage supply of the sensors/actuators, supply 1: voltage too high).
Check lines and plug connections between the following components:
- DME
- Suction jet pump differential pressure sensor
Replace differential pressure sensor.
