2019 Audi Q3

DISABLE PROCEDURE AND TIME (Always Check Service Manual)

The pyrotechnic components may be checked only when they are installed and with a vehicle diagnostic approved by the manufacturer

When working on the Airbag System (pyrotechnic components, Airbag Control Module • J234• , wiring):

1) The battery ground cable must be disconnected with the ignition SWITCHED ON. Then cover the negative terminal.
2) Wait for 10 seconds after disconnecting the battery

REV: 12/2022

PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT

Airbag control module must be replaced [MODULE,AIRBAG CONTROL]:
• With driver and passenger airbag deployment “but not with airbag generation 9.•, 10.• and 8.R”
• After three side airbag, driver, and passenger airbag or belt tensioner deployments.
• if housing is damaged
• if there is deformation on tunnel in 200 mm circumference around control module

Always replace the following:

• All deployed airbag units [AIRBAG,STEERING WHEEL; AIRBAG,INSTRUMENT PNL; AIRBAG,FRONT SEAT; AIRBAG,REAR SEAT; AIRBAG,ROOF]
• The Battery Interrupt Igniter • N253-

Also with passenger airbag deployment:
• Instrument Panel
• Deformed passenger front passenger airbag unit (cannot be reformed).
• All sensors for front airbag on front end [AIRBAG SENSOR,FRONT]
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region [AIRBAG SENSOR,SIDE; AIRBAG SENSOR,QTR PANEL]

Also with driver airbag deployment:
• Coil connector with slip ring [CLOCK SPRING]
• All sensors for front airbag on front end [AIRBAG SENSOR,FRONT]
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region [AIRBAG SENSOR,SIDE; AIRBAG SENSOR,QTR PANEL]

Also with side airbag deployment:
• Pressure sensors on deployed side [AIRBAG SENSOR,SIDE]
• Cross acceleration sensors on deployed side [AIRBAG SENSOR,QTR PANEL]
• Seat cover. Always replace the backrest upholstery if the side airbag deploys.
• Cushion
• With folding rear seat backrests: side cushion (if equipped)
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region

In addition:
• All belt retractors with deployed belt tensioners
• All belt retractors with deployed belt force limiters (depending on equipment)
• Seat belt latches for all automatic belt retractors with deployed seat belt tensioners with the belt on
• Seat belt height adjuster (manual and power) for all automatic belt retractors with deployed seat belt tensioners with the belt on

• Always replace the backrest upholstery if the side airbag deploys.
• After an accident, all damaged parts must be replaced. If no airbag unit damage is detected, the 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.

PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED

After an accident, all damaged parts must be replaced.
• If needed (visual inspection), the following must also be replaced: all faulty components

• Child seat anchors must be checked for damage or deformation after a collision.
• Each time an airbag or passenger belt tensioner deploys, a basic setting must be performed on the seat occupied recognition control module using the Vehicle Diagnostic Tester.
• If the seat rails and/or seat pan is replaced after an accident due to deformations resulting from a crash, the passive occupant detection system must be replaced using the “passive occupant detection system service kit”. Perform a “basic setting” on the passenger occupant detection system control module using the Vehicle Diagnostic Tester.

Seat belt system:
• Seat belt system
• Connect the vehicle diagnostic tester if there is a chance the belt tensioner and/or seat belt force limiter deployed.
• Depending on the crash, the belt tensioner may have deployed while the belt force limiter did NOT. In that case, follow the disposal information for pyrotechnic components
• If parts of the seat belt system are removed due to an accident, replace the belt system bolts

After replacing the airbag units or the control module, affix stickers (only tear-off strips) to the registration card and return the registration card to the relevant Sales Center or to the Importer for registration

Airbag Control Module:
• The airbag control module can be used for up to 2 side airbag and/or belt tensioner deployments with airbag generation 8.•, except 8.R.
• The airbag control module can be used for up to two side, driver and passenger airbag and/or belt tensioner deployments with airbag generation 9.•, 10.• and 8.R.
• After the third deployment, the malfunction display “Control module defect” appears.

• Each time an airbag or passenger belt tensioner deploys, a basic setting must be performed on the seat occupied recognition control module. Refer to Vehicle diagnostic tester
• It is necessary to replace the passenger occupant detection system if the seat rails and/or lower seat frame is replaced after an accident due to deformations resulting from a crash. Then, perform the “basic setting” of the passive occupant detection system. Refer to Vehicle diagnostic tester

All damaged securing pieces must be replaced, you cannot reshape components or make them fit.

The following components must be checked after every airbag deployment.

With a passenger airbag deployment:
• Instrument panel central tube, passenger airbag supports and passenger airbag must be installed free of tension. Replace central tube.
• Check the glove compartment for damage. Replace the glove compartment if damaged.

With a driver airbag deployment:
• Steering wheel

After every accident the seat belt system must be inspected systematically! If damage is determined when inspecting the check points, customer must be informed regarding necessity of changing belts.
