I have a 23 plate Q8 55Tfsi. It has cruise control but not the adaptive cruise control that your friend has on his car.
I suspect that the issue with the lane departure is to do with that. There must be an overlap of the systems somewhere. I would hazard a guess that you would need to disconnect the adaptive cruise control before you are able to turn off the lane assist. Just a guess but maybe you will have to delve deeper into the info folder that came with the car.
On a general point I too turn off the lane assist whenever I drive my car. In fact it's the first thing I do! An absolutely useless piece of kit and I think I have read a survey recently that 83 % of all owners who have lane assist on their cars,do likewise.
