Some addition, in case you are not aware you need a special socket for the lambda sensor with a gap for the cables like in the link below. Or you try it with a normal 22er open-end wrench (can but must not work with stuck screws) because a ring wrench is unfortunately not applicable because of the cables. Before unscrewing first disconnect the plug and connect the new sensor only after tightening the plug.
