Thanks for the reply, apologies for delay in getting back, I'm sure I used to get a notification when someone replied to a post but I don't remember getting one.I know there’s a number of complaints about the ‘dark band’, but can’t say I’ve noticed it myself.
And I certainly don’t have the problem you describe with auto headlights. I would get the dealer to check out whether there is a fault. It should be detecting tail lights ahead and maintaining dipped beam accordingly
I will pay the dealer a visit and ask him to have a look.
