BMW F Series no start ?
BMW F series key programming to FEM or BDC module.
Purchased a used or new BDC or FEM module car wont start? ( also known as CAS module or BCM body control module)
Did a software update and car wont start?
Battery died and car wont start?
Car wont communicate with scann tool?
All of the above symptoms must be confirmed with you tech that BDC or FEM is the cause of your no start.
Some models of F series switched from CAS ( key security module ) to FEM and BDC keys are now stored inside FEM and BDC Module this will cause a no start after replacing a donor FEM BDC module.

What causes the FEM or BDC to go bad.
1 Programming keys or performing a software update on a FEM or BDC module with cheap scann tool or no stable voltage charger while programing.
2 Flooded ( since the FEM or BDC module is located on right side kick panel makes it very venerable to flooding )
3 Electrical short.
4 Performing a mileage correction and locking it out.
5 Bad battery or Jump starting.
