Tanks for the files.
I found out that the broken panel is a removable separate part.
I found most of the plastic fragments inside the stem (or what ever that part is in English).
I'm going to super glue it as good as I can and then apply some filler.
After sanding it smooth i'll cover it in matte black vinyl wrap.
Removing that part left a big opening allowing all the mud and grime to get inside the door so i have to make quick fix.
Have to ask next week the stealership if they sell that part separately.
