We have no canbus reactions for various events on an Audi A4 Models B6 and B7 (produced between 2001 and 2008)(models are are the same regarding canbus).

There is no reaction for opening front left door (only sometimes recognized), front right door, rear left door, rear right door, trunk, hood.
besides that there is no recognition when putting in a reverse gear so that the rear view camera will be triggered and powered trough a power cable from DUDU7 unit. its not clear which cable will provide 12v only trough trigger instead of the existing 2 ones which seem to provide always on 12v only)

Download the the videos i made with a screenrecorder while using beta log function to display canbus events when opening 5 times each door and trunk (for the hood i need a second man which i didnt had):

Thanks in advance for your support
