hi im new here, and of course looking for advice. Have a 96 300tdi es, when locking the doors a machine gun type noise can be heard within the rear tail gate. The doors seem to lock ok, is something about to break down? Also when you open the doors the passenger rear doesnt open as the knob doesnt seem to pop up far enough so i have to open the front door put my hand inside and pull the button up, then it works, any ideas on this aswell, many thanks bedlow
