Is is possible to replace this silver section alone without removing the whole grille or bumper? And if so, how?
Cheers

 

No.

The chrome is screwed to the grill, which in turn is screwed to the bumper.

 

Laurence,

As grim_reaper mentioned, the whole bumper needs to come off. I've done this to replace the horns but it's not that difficult. Yours might even be easier since I only see parking sensors and no fog lamps or sensors behind the Mazda emblem. This equates to likely just one wiring harness that needs to be unplugged before the entire bumper cover comes off.

I've attached an official Mazda guide in case you're inclined to proceed. Several items in the guide won't apply to you - which makes it easier. You can certainly do this on your own without assistance.

Thank you!
