Hello , just bought my first Mercedes ML350CDI 231hp 2010 and already got some issues . I hope you guys can help me . Sorry for my English . The very first problem is that I don't have a horn . Already know that when I bought the car , but since last night I've got few more messages for example : ESP inoperative , DSR inoperative , Pre-safe check owner's manual and Flat tyre all this come with this orange triangle on a dash , and 2 more for a reg plate bulbs which I'll replace today . Is anybody meet this problems before and can help me ?
