I found, the ignition has to be on to write settings to the BCU. In the Valeo BCU "Settings" section when you change a setting and write, it should not send a signal to the door lock controller. To properly test if the changes have worked, Nanocom needs to be disconnected. Test using the key fob for activating the door locks.
Also, be careful you don't accidentally change other settings with the mouse. Sometimes hovering over the toggle arrows will change settings inadvertently.
Cheers
