I have a 2012 Q3 sline and the rear doors have the child locks ON. I have looked at the book and turned the plastic lug in both directions but neither rear door will open from the inside. I have checked via the mmi but nothing there deactivates the rear doors. Might well be something simple that I am missing ? I have found a plastic lug with the image of a child on the inside of each rear door, inside of the lug shown in the book....I have taken off the plastic cover to expose a white plastic lug with two holes, which might be the item to turn, but I assume it requires an Audi tool to activate ? Any advice please.
