Hello expert ! I also want to install rear-view headlights on the trailer and the machine. I will tap on the distribution box. Now I have heard that the Actros has to be in the workshop to read the new consumers into the diagnostic program or save them -or whatever…… Is this a big effort or even not necessary at all? Furthermore, I also consider installing LED front position lights, since I do not see the crane overhang at the back when solo driving. H from I also problems oden just clamp on ? What costs would that be during a workshop visit, so about above the thumb ? Thanks for your help !!! Greetings Webbl
