| Engine control unit: adapting to throttle valve control part |
| When matching with ignition switched on but engine not running the engine control unit learns the throttle valve control part limit positions and a comparison curve between throttle valve potentiometer and throttle valve positioner. |
| Adapting sequence must be performed if: |
| t
| The throttle valve control unit is removed and installed |
| t
| The throttle valve control unit is renewed |
| t
| The engine control unit is replaced |
| t
| If when installing another engine another throttle valve control unit is installed |
| Special tools and workshop equipment required |
| t
| Fault reader -V.A.G 1551- or vehicle system tester -V.A.G 1552- with cable -V.A.G 1551/3A- |
