Service Plan
Consequential faults: If additional faults are entered for the following components, these must be processed first:
- Oxygen sensor before catalytic converter.
- Hot film air mass meter.
- Intake pipe vacuum sensor.
- Intake air temperature sensor.
- Electromotive throttle controller.
- Tank vent valve.
- Camshaft sensor.
- High-pressure fuel system.
- Low pressure fuel system.
Check differentiated air intake system for tightness, thereby checking the following components as well:
- Crankcase ventilation.
- Oil filler cap.
- Oil dipstick.
- Tank ventilation system.
- Brake servo.
- Cylinder head cover.
Check exhaust system for leaks.
Replace injectors.
