Hello guys! Do you have information about the front lower grill fixation? Does someone know how to remove it and fix it back ? I have problem - this grill is starting to leave ( there is little space between the grill's lower part and the bumper) and I think there is some kind of stone or something in this space so I can't push it back. So I would like to know is it possible to remove it and if yes, how ?
thank you in advance

It's plastic welded to the bumper. If it becomes detached, the bumper will need to come off to fix it. You need a good adhesive ,like Tigerseal or Silkoflex (in the UK) the type of stuff used to fix body kits to cars and you will need clamps to hold it in place while the adhesive cures. You may be lucky and have enough plastic to re-weld it back on.

If you are going to weld it back I have read that cable ties can be used as welding plastic. Not tried them myself.

What he said ^^^.
Cheap and cheerful way to plastic weld using a soldering iron.
