How to change a Volkswagen combination switch:
- Turn on the ignition and turn the front wheels so that they are pointing forward.
- While the ignition is on, open the hood, locate the battery and disconnect the negative battery terminal. This will ensure the steering wheel remains unlocked and can be turned. Remove the key for the ignition/vehicle. Wait at least 15 minutes before proceeding to the next step.
- Lift up the upper trim that is after the steering wheel. It most models, the trim has just clips and no screws.
- Turn the steering wheel to the left to bring the side of it to the top.
- Use a flat screwdriver to push through the back of the steering wheel and release the airbag. On newer VW vehicles, there is no visible hole behind the steering wheel. There are two indents that you need to punch through with the screwdriver.
- Turn the steering wheel and release the airbag on the other side. Hold the airbag so that it does not fall. Releasing the airbag requires patience. If you need help with this step see our guide on how to remove a VW airbag.

- Remove the bolt at the center of the steering wheel using an M12 Tripple Square Bit. Have a friend counter hold the steering wheel while you break loose the bolt.
- Mark the steering column shaft and steering wheel so that the steering wheel is installed in the same location.
- Remove the steering wheel.
