As promised:When I get home from work today, I'll post a class video by which the clip is removed with a piece of cloth. Sorry not permitted to access Utube from work. I'll be using this method if the handle is held with a circlip. Will need to remove the panel to fit speakers.
On the Sandero access the speaker covers front and rear are molded part of the door panels.Can I ask why you are wanting to take the door panel off?..........if it's to fit speakers, I believe the speaker cover just come off without removing the door panel.
