SX4 Grinding noise when turning right

Hi together, I’m new here! Like most of the new ones, I also have a little problem with my car. I drive a Suzuki SX4 stairway. For a week there’s always a noise at the right turn on the left tire that sounds like a road broom. Of course I was already in the workshop. The brakes have been completely renewed. Unfortunately, the scratching is still there. The statement of the Wekstatt master was: I don’t know what it is, but they can continue driving. Maybe I should go to the Dekra to check it out. Did anyone have this problem or does anyone know what it can be? Thanks already in advance
