Headlight main beam switching in Auto

[KenA2]

I have a 2016 A250. I find that with the lighting switch in the AUTO position and driving at night there is a 2seconds delay between switching from dip to Main beam. This is not the case on my partners A200.
I have reported this to my Merc dealer as a safety issue and their response is that nothing can be done to correct.
Not happy with this so looking for views/other's experiences

By "switching to main beam" do you mean pushing the light stalk away from yourself and illuminating the blue warning light on the display?

I take it you mean the high beam assist (if your car has this function)
