The Audi TT is equipped with airbags that deploy during a collision. They are designed to cushion your body and prevent serious injuries. After airbags have been deployed, you need to replace them. You can have the airbags replaced by an auto mechanic, but the job is also one that you can do yourself, using just a few basic tools.

Instructions

  1. 1

    Park the car and turn off its ignition. Open and secure the vehicle's bonnet. Locate the Audi's battery near the front of the engine compartment. Remove the negative battery cable from the battery terminal by loosening the cable's bolt with the wrench.

  2. 2

    Open the driver's door and locate the fuse panel on the lower part of the dash, under the steering wheel. Pull out the fuse labelled "Airbags" to fully deactivate the airbag system.

  3. 3

    Unscrew the panels of your steering column with the screwdriver and carefully remove them. Locate the airbag inside the column. Loosen and remove the bolts holding the airbag in place, located behind the steering wheel, with the wrench. Pull the airbag out until you see the wires connecting it to the Audi's electrical wiring harness. Unplug the airbag from the wiring harness and discard the airbag.

  4. 4

    Plug the wires of the replacement airbag into the car's wiring harness. Gently push the airbag into the column, ensuring that it does not twist up as you do so. Bolt the airbag in place behind the steering wheel. Replace the column panels and secure them with the screws.

  5. 5

    Open the fuse panel and reinsert the airbag fuse. Reconnect the negative battery cable to its battery terminal and tighten it with the wrench. Close the Audi's bonnet.

Tips and warnings

  • Your Audi TT's computer system will need to be reset. This needs to be done at the dealer or an auto repair shop.
  • If your computer system is not reset, the new airbags may not deploy correctly, or at all, if involved in another collision. Do not attempt to reset the system yourself if you know nothing about it, or this could cause the computer system to malfunction and cause more damage.
