DTC P114F, BMW Hex Code 0x2D16, BMW Code 11542: Air Mass Flow Sensor Defective (MIN): Remarks

If the air mass period duration displayed in the environmental data is > 4500us this is an fault generated by the sensor's own self-diagnosis utility (sensor reports active problem). The response should be to replace the sensor. If the ""air mass period duration"" is < 4500us, this is an upward range violation (period duration too high) that can be caused by defects in both the sensor and the wiring harness.
