For regular F20 two warnings should be expected before too late: "engine oil at minimum" and "engine oil below minimum". No doubt there must be a critical oil pressure illumination, even in M135i. That must be logged.
Actually, before disassembling the engine they should have noticed the amount and condition of the oil there as it could be obviously related to the failure.
Anyway they must supply a valid (official, at least) reason for warranty rejection.
