This can cause a communication "block" that leads to other modules reporting invalid signals. This is less common but possible after a battery disconnect or a steering column repair.

The specific signal missing is ID: ST_ENERG_GEN (Energy Generation Status). bmw error-d52c44

Even if your car cranks and starts perfectly, a drop in Cold Cranking Amps (CCA) forces the car to limit power to secondary electronics, triggering communication flags. 3.
