I am having power steering problems with my combo, sometimes it works and sometimes it doesnt, eps light on dash does go on and off when the power steering is going on and off, ive been told it could be the speed sensor as ive already changed the power steering for another and made no difference, the speed sensor is my last option but where is it and how easy is to change, ive been told the speed sensor maybe in the gearbox is this true. please help as mot is due in a couple of days and i understand that this light is a failure.
