I'm currently running a 218i MSport convertible, the headlights are LED.
Looking at the front of the car, it has a what looks like a conventional twin headlight arrangement. Turning on the main beam the outer pair of lenses illuminate. However when putting on the high beams, instead of the inner pair of lenses being used, the high beam uses the outer pair of lenses too. So it appears that the inner pair of lenses have no actual function, except to house daylight running lights out the outside.
This seems a bit odd, why wouldn't the designers use separate lenses for the main and high beams?
Yes, our 2015 X3 was the same. My 2016 Octavia has large rectangular light clusters with a DRL LED strip along the lower edge, but all the headlight functions are provided by the outer circular light unit; the remaining inner area (where one would expect spotlights to be) is unused.
