The post you link just seems to suggest that the flap leaked or that a gasket went or something. Tbh, that's just on par with any car where anything can go wrong. Had the flap broken off and the engine got mashed, then we might have an example.
As such, I still stand by my guns that there are no reported swirl flap failures on the E9x. Willing to be corrected tho.

Fair enough. I would guess the swirl flaps must have been modified along the way so the spindle doesn't break.
