| Reference table for reading out letters and/or numbers on each injector |
| When a new injector is installed, the adaption value for the new injector must be written into the engine control unit. |
| When the engine control unit is renewed, the appropriate „injector delivery calibration“ values with „injector voltage calibration“ values must be written into the new control unit. |
| The adaption procedure is described in the Guided Fault-Finding. (The procedure is described under Guided Functions.) |
| In addition to this check whether the correct calibration values of the „injector delivery calibration value“ and „injector-voltage calibration value“ of the remaining spraying valves are entered. Do NOT attempt to re-enter these calibration values if the correct values are already stored in the engine control unit. |
| Select the correct vehicle in Guided Fault Finding. |
