I got that same error on my EQS AMG 53 for a while "Check low beam setting". It was set correctly but then it kept thinking the setting was wrong. I think I eventually worked it out - we drive on the left so the car is expecting other vehicles to be on the right of me, but every morning when I leave home there is a row of parked cars on my left so I have to drive on the right hand side of the road for about 100 yards. So I think the "clever" technology sees those cars and sees I an on the right hand side of the road and thinks I have set it up incorrectly. (This is only speculation but it seems credible). So now I have it on automatic and I just let it do its thing.
