Who replaced the CAS? If it was replaced at a dealership or a good BMW specialist shop, it will be warrantied. Certainly, you're going to want to connect the car to ISTA (BMW's diagnostic system), to diagnose the current (CAS?) failure, as well as the parasitic drain or charging failure.
Without the ISTA diag, you're just going to be guessing.
