According to the specifications and materials of the BMW 3 series pump bracket screw, its torque is generally about 20-25 Nm. However, the specific torque value also needs to be adjusted according to the specific model and screw material, so it is recommended to refer to the official maintenance manual or consult a professional technician when carrying out maintenance or replacement. The correct torque value can ensure the safety and stability of the screw fastening, while avoiding the problems caused by too tight or too loose.
