Keep getting docked for not having them on because there appears to be no way to turn on the DSD so that the game recognizes it, even though the valve is operable. The helpful reminder keeps telling me to turn it on for more points- well, it IS on. The three valves are at the top of the cab wall (and can only be activated in order)- but keyboard maps for some reason do not work on this model.
Found the class 37 ROG DSD cut out the power for at least around 10 seconds, is normal? EDIT: you have to press it manually because not reset whit "circle button" on PS4
