  6. Have the friend pump the brake pedal a few times, then keep the brake pedal pressed.
  7. Loosen the brake screw and wait a few moments for the brake fluid to come out. Tighten the bleed screw while your friend continues to hold the brake pedal down.

If your BMW brakes continue to feel soft (mushy), the next step would be to bleed the ABS pump, also known as the DSC pump, in BMW terms. You must use a BMW scanner to activate the DSC motor and bleed the system.

Procedure

These steps will vary depending on the scanner that you are using.

  1. Connect your scanner to the OBD-II port under the dashboard.
  2. Turn on the ignition.
  3. Select your BMW model.
  4. Go to Body and select Dynamic Stability Contol or (DSC)
  5. Call up ECU functions or Adaptations.
  6. Perform DSC Pump Motor activation / Brake Bleeding.

Rheingold ISTA/D + ISTA/P

  1. Connect ISTA/D to your BMW and load the software.
  2. Select Vehicle Management in the upper bar.
  3. Select the Service Function.
  4. Select Chassis and Suspension
  5. Traction Control
  6. Brake Bleeding Routine
  7. Press Start on the bottom right.

Once you complete the BMW brake bleeding procedure, your brakes should feel much firmer. Monitor the brake fluid level in the next few days and ensure you are not losing any brake fluid.3
