AFS on my 2007 3L MS spec definitely works. Country roads highlight it best. Turning round a corner, then letting go of the wheel to let it correct itself will show it clearly. You can see the beam of light actually moving back to a straight position. I also noticed that when you turn on the lights, they appear dim, then brighten within a few seconds. I always thought that was just the type of bulb warming up yknow? But it may well be the AFS system doing a self-check. I'll have to stand outside the vehicle and get my partner to turn them on while I watch. She can't even notice AFS working on the country roads, but to me it's clear they are indeed operating normally!
