Insurance question;-(

hello together, I got last fr. my new a4, everything great, also directly tore down the first 600km and was positively surprised that the sline suspension of my opinion is fantastic and not too hard! a really unsafe driving behaviour with strong braking maneuvers from high speeds and I really have to confirm! that’s really bad! but now to the actual question: after only one day the pitch had hit me. I was on the a3 of ffm rich In the middle, my front man climbed into the iron, made a stroller and drove over a plastic object in order not to touch it with the ripe ones. this so-called moved the plastic object an upswing, saw the part fly towards me, from evasive could be no talk at the speeds, at the traffic and the unexpected object. cool grill broken, scratcher on bumper and bonnet. who is to blame? who pays? I have the identification mark, his it was not what had come against me. was a well-kept 3er bmw cabrio newer design. is fully kasko insured, runs over the asl leasing! Greetings, rash82
