i'd like to know how the automatic gearbox of my Q5 is working. i've got 3 options of driving, i.e. comfort, auto and sport. is there somebody who can tell me when the gearbox is activated. is that by the rpm or the speed. furthermore, what rpm-levels belong to comfort, what by auto and of course what by sport. or, in case of speed-level, what levels belongs to what. i tried to ask the same to audi direct, but they don't want to answer an email. even my garage doesn't want to help.
