Hey Omar, after replacing the battery does engine still cranks? If so then you have to match engine computer with your key computer. What I mean by that is they share rolling codes, if key computer does not match with your engine computer it will not let you start the vehicle.

The possibility exists that the EWS is not aligned to the DME. When this happens the starter will not activate. Replacement of parts(the starter) is useless. The only way to address the issue is to re-align the modules and to do that requires special tools that either the dealer or some BMW repair shops have. Also there is a need to confirm that what I said is indeed the case, and a scan with the proprietary BMW scan tool is going to need to happen. You might need to tow the car to the shop that can do the scan I mentioned.

It should be about one hour for the diagnosis and repair, but that is just a guess.
