[AusF20/F48]

Hi Harkes
I think you need to talk to whoever did the repair as it looks like it could have been an after market front that was used.
looking at the edge, it looks like some of the inner panel has been removed.
I am not sure what your insurer's policy is but I would ask them to fix it properly.
I had a look at a M135i for you today and this is the front light (F20)
It is the same fitment as my 125i M Sport (no visible gap)
