Action in service

Rectify any faults saved on monitoring the voltage supply for the sensor system/actuators (5 V) (voltage outside the valid range) first.

Perform the system test (wastegate valve, exhaust turbocharger, etc.).

Check the air duct between the exhaust turbocharger and intake plenum.

Check wires and plug connections between the following components:

• DME
• Intake pipe pressure sensor

Replace intake pipe pressure sensor.
