The exclusive range with Audi is that they have a colour chart you can choose from, Ara Blue being one of them, but they declined that apparently because of the sensors and radar system. Usually audi exclusive let you submit any colour however not necessarily from audis own range then they approve or decline it. Currently they're declining everything.
I've just submitted Estoril Blue which is a BMW colour, and having personally owned an SQ5 in that colour in the past I know they CAN do it with Adaptive Cruise etc but I'm waiting to see what they come back with.
