how to fix my BMW 5 Series F10/F11 (2010-2017) if it won't shift into gear

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the emergency brake is engaged.
• Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set
• Remove the transmission fluid drain plug (if equipped) and drain old fluid into a container.
• Replace the drain plug and torque it to manufacturer specifications.
• Using a transmission fluid pump, fill the transmission with the correct type of fluid until it reaches the full mark on the dipstick.
• Start the engine and let it idle in park for a few minutes, then check the fluid level again and top off as necessary.

3. Inspect and Repair Shift Linkage

• Tools Required: Socket set, screwdrivers
• Remove the center console trim and access the shift linkage.
• Inspect the linkage for any wear, bending, or disconnection; repair or replace components as needed.
• Reassemble the console and ensure the gear selector moves smoothly through all positions.

4. Replace Brake Light Switch (if faulty)

• Tools Required: Flathead screwdriver, socket set
• Locate the brake light switch, usually found above the brake pedal.
• Disconnect the electrical connector and remove the switch from its mounting bracket.
• Replace with a new switch and reconnect the electrical connector.
• Test the operation of the switch before reassembling any panels.
