What model and year? On my '87 w124 300E the hood star is removed by using a pair of needle nose pliers to pull out the lateral pin at the bottom of the hood assembly. Installation of the new star is via rotating the spring loaded assembly. A search on "removing hood star" will give a number of discussions on this topic, including Removing hood ornament
. Have fun!
