Has zero to do with BMW..
The damage that you see is not to your bumper...its too your "bumper cover".. (im not being an a$$hole with semantics..just trying to explain)
Ever since OEM's went to pretty aero stylized front and rear facias, your "bumpers" were nicely covered up by the purely cosmetic bumper covers. What do you think actually absorbs impact in an accident...surely not that piece of plastic.. All of the structure is hidden nicely and is made from aluminum and steel and prtected by more plastic and foam.
The protusion you see is from the force of the car that hit yours, squishing the cover against the support which lies underneath..
and be happy we have those covers... or else we would be stuck with a big old chrome bumper like on a chevy caprice....or worse a cadillac !!
sorry for your loss...good thing is is that it s a relatively easy fix.
the big lump of metal indicated by #1 is what did the damage
