BMW G20 ROCKER PANEL REMOVAL PROCEDURE

I need to remove one of my rocker panels from my 2019 G20 330i. I could not for the life of me, find any useful information regarding this topic. I created my own and figured it wouldn't hurt to share it with others. If any of you have done this before, advice is always welcomed.

1. VEHICLE PREPARATION

• Park the vehicle on level ground and set the parking brake.

• Turn the front wheels outward to increase wheel-well accessibility.

• Lift the vehicle using BMW jack points if additional underbody space is required.

• Support using jack stands before performing any underbody procedures.

2. FRONT WHEEL-WELL FASTENERS

• Locate the two T20 Torx screws at the front lower wheel arch.

• These screws secure the forward end of the rocker panel to the inner fender liner.

• Remove both screws using a T20 driver.

3. REAR WHEEL-WELL FASTENERS

• Locate the two T20 Torx screws at the rear lower corner of the rocker.

• Remove both screws. These hold the rear lateral edge of the rocker in place.

4. HIDDEN RETAINING BOLT

• Behind the rear wheel liner, some trims contain an internal 8mm bolt.

• Pull back the liner carefully and remove the bolt with an 8mm socket.

5. UNDERBODY SCREWS

• Identify 8–10 T20 Torx screws along the underside of the rocker panel.

• Support the rocker while removing the final screws to prevent flexing.

6. UPPER CLIP RELEASE

• The rocker is secured by upward-locking compression clips.

• Push upward toward the door sill, then gently pull outward.

• Work from the center to each end until all clips disengage.

7. PANEL REMOVAL

• Support the panel with both hands and pull outward away from the vehicle.

• Place it on a padded surface to avoid paint damage.

8. REINSTALLATION

• Inspect and replace any damaged clips.

• Align the rocker and engage the top clips first by pressing firmly.

• Reinstall the underbody screws, wheel-well screws, and 8mm bolt (if equipped).

• Ensure the panel sits flush and correctly aligned
