Yes it can be fixed and the BMW kit does come with the part you need.
Realoem doesn't show any pics of the kit, However the link below to ECStuning in the US does show pics of it

I've also responded in your wanted thread with a question, I'm wondering do you need a bumper at all, or just a new mounting bracket?
