Audi Q5: 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. Refer to 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.
- Ensure the seat upholstery 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 (32 ºF to 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 seat occupied recognition control module. Refer to 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. Refer to Vehicle Diagnostic Tester.
Passenger Safety System Pyrotechnical, Electric and Mechanical Components, Replacing After a Collision
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
Note
- The airbag control module can be used for up to two deployments of the side, driver and passenger airbag and/or belt tensioner with airbag generation 8.* "not 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.
- Airbag control module must be replaced:
- with driver and passenger airbag deployment "but not with airbag generation 9.*, 10.* and 8.R"
- after three side, 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 triggered airbag units
- The Battery Interrupt Igniter -N253
Also with passenger airbag deployment:
- Instrument Panel
- deformed passenger module supports (cannot be reformed)
- all sensors for front airbag on front end
- Remaining cross acceleration sensors if anchorage point is deformed in sensor region
Also with driver airbag deployment:
- Coil connector with slip ring
- all sensors for front airbag on front end
- Remaining cross acceleration sensors if anchorage point is deformed in sensor region
Also with side airbag deployment:
- Pressure sensors on deployed side
- Cross acceleration sensors on deployed side
- Cover
- Cushion
- With folding rear seat backrests: Side upholstery (if present)
- Remaining cross acceleration sensors if anchorage point is deformed in sensor region
In addition:
- All automatic 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
- 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 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".
- Also: Follow the seat belt inspection, 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 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: Remove the steering wheel and place it with the rim on a flat surface. The entire steering wheel rim must rest on the surface. Otherwise, steering wheel should be replaced.
- Check steering wheel for smoke residue. If smoke residue is present, replace 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 inspected separately.
