Dear Community, my 850er Kombi Bj. 95 was delivered with a detachable coupling. Unfortunately, the hook cannot be dismantled. At the coupling side right is a lever, which you only have to turn down, then the thing should dissolve. But I failed despite all efforts and fineness respectively roughness. In a post I read once that there were problems with these AHK passports, and that the AHK were therefore fixed by the workshops. Can someone confirm this, knows the “problem” or has a tip? Thank you and thank you very much, Bernhard
