Hello dear G-driver! Unfortunately I have a problem with the differential locks (Bj. 10/2016, since 2/2018 my G): The first lock can be easily selected and then activated after at least a few meters (red lamp). Second and thus third can be selected, but the red lights do not shine. I was already with Mercedes twice and a new sensor (o. e.) was installed and told me that the locks are activated only when the wheels spin. m you can only test the electronics in the workshop and they say that everything is fine. However, I don’t think so, because with the test car I drove before (but not bought), the locks were activated without any problems. Can someone help me? At the moment I am only on the road in the home light to middle terrain, but I don’t want to lie down if it gets heavier and the locks don’t jump in at the end. Thank you!
