Hello again guys,
So OK, I replaced that metal piece with original part and mounted it back and looks just fine.
So now, when I start the engine 'AFS off' is on ( not flashing but is on ) and I am able to turn it off and on with the switch in computer but after ~5sec the 'AFS off' starts flashing and computer no longer reacts to On Off commands.
Any advice ? maybe I should restart somehow the system or is it issue with some other component?
