I took delivery of my 2011 F10 last week. Loving everything about it but still getting used to some of the functionality. I have comfort access and, from time to time, want to unlock the doors for passengers, too. When I grip the handle, only the driver's door unlocks (unless I am at a passenger door). What do I need to do if I want the other three doors to unlock? Hold the handle longer? Tap it again? In advance, thanks for your help.
