Solution

1. Preparation

Gather tools required for the reset process.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

Turn on the ignition without starting the engine (press the start button without pressing the brake pedal).
Access the iDrive menu by pressing the "Menu" button.
Navigate to "Settings" using the iDrive controller.
Select "Drive" from the settings menu.
Scroll down to "Transmission" and select "Reset Transmission" or "Reset Adaptations."
Confirm the selection to initiate the reset process.

3. Perform a Transmission Adaptation Reset (if necessary)

With the ignition still in the on position, press the accelerator pedal fully to the floor and hold it.
While holding the pedal down, turn the ignition off and then back on without starting the engine.
Release the accelerator pedal after 10 seconds.
Start the engine and allow it to idle for a few minutes to complete the reset.

4. Test Drive

Take the vehicle for a test drive to confirm that the transmission is shifting smoothly and that any previous issues have been resolved.
