Any news David?
I had a more detailed look at mine and the reflectors are terrible - in fact the first time I looked, I decided that they can't be a reflector and it must work some other way.
They are mostly just dull tarnished beige not reflective at all where they need to be . What garbage (Hella) for a light that is £1,200 each!
I am also not too sure they can be removed. Some say with AFLS they can't be withdrawn from behind like on the simpler version (but this was for the A6 of same vintage).
I am loathed to start trying to take it apart and end up ruining something and it's not like I have a spare part to put in there.
They seem a bit fragile and have dodgy wiring. Check your bunch of shiny black wires inside the light, I have seen on youtube one can snap at the end with metal fatigue due to being too taught and moving back and forth all the time with the lamp swivelling.
Here is some useful info ...
