Volkswagen Touran (1st generation): Driver Airbag Module Replacement

The driver airbag module is secured to the steering wheel with Torx screws and connected by a single connector to the squib (igniter). The procedure is simple, but it involves a pyrotechnic component, so you need strict discipline and the vehicle must be de-energized. Replace the module after deployment, if the housing is damaged, or as required by a recall campaign.

Difficulty: Medium Time: 30-60 minutes Steps: 13 Tools: Torx socket or bit (sized to the mounting screws, usually T30-T40), thin flat-blade screwdriver, 10 mm wrench for the battery terminal, non-conductive mat or cloth

Part

  • 🔩 Driver airbag module (complete airbag assembly for the steering wheel) matching your steering wheel version: two- or three-spoke, with or without multifunction steering wheel buttons. The clock spring (steering wheel contact reel, Airbag-Wickelfeder) and the SRS control unit are separate parts, so don't confuse them with the module

Step by step

13 steps
  1. Park the car on a level surface with the wheels and steering wheel set straight ahead. Remove the key from the ignition and close the doors so nobody can accidentally switch the ignition on.
  2. Disconnect the negative battery terminal and move it aside so it can't touch the battery post. Wait at least 15 minutes: the capacitors in the SRS control unit must discharge.
  3. Remove the cover plugs or inspect the back of the steering wheel behind the spokes on the left and right. The module's mounting screws are on the sides, in holes on the rear of the steering wheel. For easier access, turn the steering wheel slightly to the side so you can see each screw.
  4. Remove both Torx screws. Don't pull the module out abruptly: it is held by the connector, and the wiring is short.
  5. Carefully lift the module toward you and place it on your lap or on the steering wheel with the front face up. Never place it face down.
  6. Release the orange locking tab on the connector at the module, then disconnect the squib connector. If the module has a second connector (horn connection), disconnect that one too.
  7. Remove the old module and set it away from the steering wheel.
  8. Connect the connectors to the new module. The orange locking tab must click into place.
  9. Install the module in the steering wheel. Don't pinch the wires, and make sure they don't interfere with the module seating.
  10. Tighten the two Torx screws evenly. Use the torque specified by the manufacturer; the exact value is not confirmed in publicly available sources. Don't overtighten: the housing is plastic, and the screws carry only a light load.
  11. Reconnect the negative battery terminal. Switch the ignition on while keeping well back from the steering wheel: the Airbag warning light should come on and go out after about 4 seconds.
  12. Press the horn: it should work. Check that the steering wheel has no play and that the gaps around the module are even.
  13. If the Airbag light stays on, read the fault codes with a diagnostic scan tool. The cause is often a poor connector contact or a previously stored deployment code that needs to be cleared. If the fault won't clear, you will need diagnostics with a scan tool that supports SRS.

Common mistakes and warnings

  • An airbag is a pyrotechnic component. Don't open the module, drop it, test it with a multimeter, or apply voltage to the connector. Store the old module face up, away from heat sources and electricity. Install only a serviceable module with no signs of tampering or damage. If you have no experience working on SRS systems, have a repair shop do the replacement. Your safety in a crash depends on correct installation.
