Audi Q7: Airbag, Belt Tensioner and Battery Cut-Out Units, Storing, Transporting and Disposing (Pyrotechnic Components)

Audi Q7 (4M) 2016-2024 Workshop Manual / Body / Body  Interior / General, Technical data / Airbag, Belt Tensioner and Battery Cut-Out Units, Storing, Transporting and Disposing (Pyrotechnic Components)

  • Storage must conform to national legislation.
  • Transport must conform to national and international guidelines, whereby packaging, identification and shipping documents are controlled to the greatest detail.
  • Undeployed pyrotechnic components must be disposed of in an orderly manner, conforming to national legislation, in their original packaging! Direct questions to the importer.
  • Only pyrotechnic components, which have been ignited completely, may be disposed in industrial waste.


  • This does not apply to belt tensioners that function according to the Wankel pretensioner principle. These are to be treated like undeployed pyrotechnic components (such as airbags, seat belts, pyrotechnic battery cut-out elements).
  • Workshop equipment cannot determine if Wankel belt tensioners have deployed all pyrotechnic materials.

Airbag Control Module, Additional Safety Precautions


  • After every removal and installation of the Airbag Control Module -J234-, the Guided Function "Inertial sensor basic setting" must be performed.
  • If the Airbag Control Module - J234- is replaced with a new part, the basic setting within operation must be performed using the "15 - Replace airbag control module" program.
  • If the Airbag Control Module - J234- is removed and then the same one is reinstalled, perform the "Inertial sensor basic setting" as described in the following:

- Connect the Vehicle Diagnostic Tester.

- Switch the ignition on.

- Select and start the Diagnostic operating mode.

- Select the Test plan tab.

- Select the button Individual tests and select the following tree structures one after the other:

  • Body
  • Body Assembly
  • 01 - OBD-capable systems
  • 15 - Airbag - J234
  • 15 - Airbag, Functions
  • 15 - Basic Setting
  • 15 - Inertial Sensor Basic Setting

- Start the selected program and follow the instructions in the display of the Vehicle Diagnostic Tester.

Additional Thorax Airbag Safety Precautions


  • We recommend using original equipment seat covers.
  • Seat covers or protective covers that are not specially approved for use on Audi seats with thorax airbags must not be used.
  • Do not cut the backrest material in thorax airbag area.
  • When installing, the seam in thorax airbag region must run straight.
  • All upholstery clips must be replaced (metal and plastic clips).
  • Using original equipment upholstery clips is recommended.
  • During installation, all upholstery clips must be placed in the same place they were when they were removed.
  • If cover is damaged (with rips, burned holes, etc.) in thorax airbag region, it must be replaced for safety reasons so that airbag deploys correctly.
  • Do not repair the backrest cover in the thorax airbag area (because of special materials and strictly defined seams).
  • Always replace the backrest cushion if the thorax airbag deploys.
  • After an accident, all damaged parts must be replaced. If no airbag unit damage is detected, the airbag unit can still be used.
  • If thorax airbag units are replaced, the new thorax airbag number sticker should be removed and placed over the old sticker on the seat pan.
  • Do not poke the cover with an upholstery needle or other sharp objects near the airbag, the Front Passenger Seat Occupant Sensor -G128- or the passenger occupant detection system mat.

Additional Head Curtain Airbag Safety Precautions


  • Visually inspect the trim panels for damage every time before installing.
  • Do not make any repairs to the trim panels (upper A-pillar trim panel, B-pillar-, C-pillar-, and D-pillar trim panels).
  • Ensure secure trim panel fit when installing.
  • Always replace the entire module when making repairs behind the head curtain airbag.
  • Handle head curtain airbag modules with great care when removing and installing them to prevent causing any damage.
  • Place any removed head curtain airbag modules back in their transport containers or on a clean and even surface with a cloth underneath.
  • After servicing the body in the vicinity of the head curtain airbag, check the body for welding beads, deformation and chafe marks (compare with opposite side of vehicle if necessary).
  • As long as the gas generator is NOT attached, hold it securely when transporting, removing and installing, etc.
  • Never rotate, coil, knot, throw, slide, push, hang, squeeze, press, pinch or clamp the head curtain airbag module.
  • They may be folded as long as this does not damage them, especially the protective cover.

Front Thorax Airbag Crash Sensors (Pressure Sensors) Safety Precautions

The thorax airbag crash sensors react to changes in pressure and therefore must be handled very carefully. Note the following points:


  • Always pay attention to the correct installation position and only install at the specified component location in the doors.
  • Protect the crash sensor from bumps and impacts. Do not use a crash sensor if it has fallen on the floor. When doing body work on the door, the crash sensor should be removed.
  • The crash sensor is calibrated to the volume of air inside the door. If the door is deformed resulting in a reduced air space inside the door, the function of the crash sensor will be impaired.
  • Avoid contamination of the crash sensor. Do not use compressed air in the area surrounding the crash sensor. Protect crash sensor from filings or shavings (for example, when installing door speakers later). Do not use cavity sealant or spray lubricant in the area of the crash sensor.
  • Protect against heat and cold. Avoid heating, for example when painting or doing other body work. Crash sensors should not be subjected to temperatures below -40 ºC (-40 ºF) (for example, in non-climate-controlled airplane cargo holds).
  • Protect the crash sensor from moisture when storing or installing it.

For proper crash sensor function, effective door seal must be ensured after installation. Note the following points:

  • All components (for example, cover, speaker, door trim panel) must be installed correctly.
  • The door trim panel clips seal the system. If necessary, replace the clips.
