The DDE 6 process differs slightly:
First we will select our model, in this case it is an E60 twin turbo engine. This will take us to the menu for this ECU:
On this menu, click F6 for ‘Ansteuern’.
Next click F1 for EWS/CAS .
If you get an error, just click OK.
Next click F2 for reset.
If you get an error, click OK again.
If you get the message above, click F2 again.
If all has gone well you should get a message in German which says the process has been sucessful.
