Swirl flaps or stepper motor?
Great thread with some ingenious ideas for fixes. I have similar issues on my xc90 but also with the motor itself. Got a massive power loss which I'm investigating. When I start the car I think the stepper arm moves and when I rev gently the arm moves too. However, if I hold revs about 2000rpm, the stepper arm moves back down and doesn't hold position?
