Need to remove front

2016 E4 need to put siren in cart think it would be easier with body off. Where can i find info on how to remove front end?
THANKS

Start popping off the black rivets - Two bolts next to the charger port, Two bolts under the front fender.

Easy Peasy.

THANKS MIKE ,Are they regular rivets?

No, they are the plastic ones, pull out the center pin and then pull out the rivet, standard plastic panel attachment.
