I absolutely hate it when they need to dim or even switch off the DRL on one side to make the front indicator visible. Not an Audi-exclusive "feature", but prominent on them.
The blue in the headlight will be the laser spot illuminating pedestrians, same as the 7 series has. For some reason it's blue, I assume it's because Osram patented it and now sells it to manufacturers, but forces them to have this identifying colour.
