DTC P323D, BMW Hex Code 0x2D78, BMW Code 11640: Control Module Monitoring Air Mass Flow Balancing, Control Range Monitoring (PLAUS): Remarks
The torque monitoring feature compares the torque demand (from accelerator pedal, FGR, electrical equipment, transmission) with the torque provided (calculated from HFM, injector valves, ignition angle, throttle valve angle, differential pressure, lambda). Deviations trigger fuel-supply safety shutdown to prevent vehicle from autonomous acceleration.
