Explanation Of First Start Function
WARNING: This page is about a different variant/trim than selected.
Information
After working on the fuel system, air in the system makes it more difficult to build up fuel high pressure.
The First start function saves time by:
- Starting at low pressure.
- Displaying the fuel high pressure diagnosis.
- Allowing air to escape more quickly via the injectors.
- Preventing fault entries or replacement measures while pressure is building up.
Run the First start function following all removal and installation work on the high-pressure system if the fuel system was opened.
