In some cases the EGS reset and adaptation might not be possible via OBDII, but we have a solution for that too. The EGS reset (make virgin) procedure can be done on bench, using the ZN079 cable set and the ECU Programming Tool. Please refer to the “ ZF 8HP Virgin - Adapt for BMW“ section of the ECU Programming tool User Manual for all details on how to reset the EGS by dump.
ZF 8HP BMW Make Virgin with ECU Prog
1. Read the ZF 8HP unit’s Data Flash with the ECU Programming tool and the ZN079 cable set and save the data to a file.
2. Load the file in the Dump tool
3. Press the “Virginize” button - this will create a new file that you need to save again.
4. Go back and write the file to the unit
Now the EGS is in a virgin state, you can install it into the vehicle to proceed with adaptation.
ZF 8HP adaptation (if the unit is virgin)
- (Procedure is executed in the vehicle)
Once you have the “virgin” EGS unit installed into the vehicle, you need to complete the following steps in order to adapt it:
1. Turn IGN ON - wait for 2 min.
2. Turn IGN OFF - wait for 2 min
3. Repeat 5 times
In other words, you need to turn Ignition On for 2 minutes, than turn Ignition Off for 2 minute, than IGN ON for 2 min, IGN OFF for 2 min until you repeat ON and OFF 5 times each, which should make the procedure 20 minutes long.
Important notes
- The cycling is the adaptation. Interrupting it or shortening the intervals leaves the unit unadapted.
