TAXIst писал(а):зарядка 13.5-13.7В... Вроде вполне нормально. У меня по климату ошибка с малым напряжением с момента покупки... Так где ему мало напряжения? куда конкретно лезть?
ну так посмотри напряжение на самом климате.. или ВАГом или в самодиагностике.
а по поводу первого канала в текущем опросе, там показывается причина незапуска компрессора
