3x 10mm nuts at the back of the grill and then 2 white plastic clips that you have to squeeze together and then it pushes out. Thats how to get the grill out anyways.
The Badge, there are 2 metal prongs, im GUESSING that you have to push these in order to get the badge out, but i havnt tried. . .iw ill b buying another bad soon so will want to know.
The badge is stuck to the grill, I found drilling a whole through the back of the grill behind the badge helped. I was then able to knock the grill out fairly easily. Took about an hour to remove, and re-fit to car.
