Audi Q7: Passenger Occupant Detection System Deactivation Additional Safety
Precautions, Market-Specific
Caution
- After each repair to the front passenger seat where
the seat or backrest cover was
"removed", a basic setting of the passenger
occupant detection system control module must be
performed using the Vehicle Diagnostic Tester.
- Do not bend the passenger occupant detection system
mat.
- A leaking mat must be replaced (service kit).
- Do not bend the passenger occupant detection system
pressure hose.
- Make sure the components of the passenger occupant
detection system do not fall onto hard surfaces, do not
come into contact with grease and do not risk damage by
resting against sharp objects.
- The mat, the fleece and various covers must be
fitted to be free of folds.
- Make sure the seat padding and cover are positioned
correctly when installing.
- Replace all upholstery clips or clips and make sure
they are positioned correctly on the seat.
- The system basic setting can be performed at
temperatures between 0 ºC and 40 ºC (32º and 104 ºF)
with 8.R and 9.* airbags. The temperature must be
between 5º and 35 ºC (41º and 95 ºF) with 10.* airbags.
- Make sure that no objects are placed on seat when
performing basic setting.
- The use of additional seat cushions such as pillows
impairs the function of the passenger occupant detection
system and the operation of the airbag system.
Passenger Occupant Detection System Deactivation After a Collision,
Market-Specific
- Each time an airbag or passenger belt tensioner deploys, a
basic setting must be performed on the passenger occupant
detection system 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
passenger occupant detection system must be replaced using the
"passenger occupant detection system service kit". Perform a
"basic setting" on the passenger occupant detection system
control module using the Vehicle Diagnostic Tester.
Restraint System Pyrotechnical, Electric and Mechanical Components,
Replacing After a Collision
Special tools and workshop equipment
required
- Vehicle Diagnostic Tester
The Airbag Control Module must be Replaced:
- If the display "Control module faulty" appears after a
Diagnostic Trouble Code (DTC) memory check
- After three side, driver, and passenger airbag or belt
tensioner deployments
- If housing is damaged
- If there is deformation in the tunnel in a 200 mm
circumference around the control module
Always Replace the Following:
- All deployed airbag units
Also with Front Passenger Airbag Deployment:
- Instrument Panel
- Deformed front passenger module supports (cannot be
reformed)
- All sensors for front airbag on the front end
- Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area
Also with Driver Airbag Deployment:
- Return spring with slip ring
- All sensors for front airbag on the front end
- Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area
Also with Thorax Airbag Deployment:
- Pressure sensors on the deployed side
- Transverse acceleration sensors on the deployed side
- Cover
- Cushion
- With a folding rear seat backrest: side cushion (if
equipped)
- Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area
Also:
- All automatic belt retractors with deployed belt tensioners.
- All automatic belt retractors with deployed seat belt force
limiters (depending on vehicle 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
- Connect the Vehicle Diagnostic Tester if there is a chance
the belt tensioner and/or seat belt force limiter deployed.
- In "Guided Fault Finding" under
"15 - Airbag", check whether there is a crash entry in the
airbag control module.
- Also check if the "Resistance too large" error is stored for
the belt tensioner and/or belt force limiter. Deployed belt
tensioners and/or belt force limiters must fulfill both
conditions. "Requirement: the airbag control module was not
replaced yet".
Note
- The "Resistance too large" error may also be stored if there
is an open circuit. Then there is normally no crash entry.
- 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. Refer to
→ Chapter "Airbag, Belt Tensioner and Battery Cut-Out Units,
Storing, Transporting and Disposing (Pyrotechnic Components)".
- Also check the seat belts. Refer to
→ Chapter "Seat Belts, Checking".
- If parts of the seat belt system are removed due to an
accident, replace the belt system bolts.
- If needed (visual inspection), the following must also be
replaced: all faulty components.
- 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 Fasteners, Checking After a Collision
All damaged fastening elements must always be replaced.
Reshaping the components or "making them
fit" is not permitted.
The following components must be checked after every airbag
deployment.
With Front Passenger Airbag Deployment:
- Instrument panel central tube; front passenger airbag
supports and passenger airbag unit must be installed free of
tension. Otherwise the central tube is to be replaced.
- Check the glove compartment for damage. Replace the glove
compartment if damaged.
With Driver Airbag Deployment:
- Steering wheel: Remove the steering wheel and place it with
the steering wheel rim on a flat surface. The entire steering
wheel rim must rest on the surface. Otherwise the steering wheel
should be replaced.
- Check steering wheel for smoke residue. If smoke residue is
present, replace the steering wheel.
Collision without Airbag Deployment
- If the Airbag Indicator Lamp -K75- does not indicate a malfunction,
then it is not necessary to replace the pyrotechnic components. Seat
belts must be checked separately.
