bro drexchen...
i dunno, so i wondering about it... coz when i look at the part for auto cruise there got too many sensor which is needed for TCU to change gear in auto-cruise mod...
i also use auto-cruise last time in auto, when i turn auto-cruise mod on the gearbox will automaticlly change gear when the speed decrease, that's why i dont understand if manual can do it, if manual got i think not as good compare with auto tranny.. :D
but when the climbing is to heavy, the auto-cruise will automatically turn off...
