Component Exchange After Airbag/Seat-Belt Pretensioner Triggering

The following components must be removed and replaced after the airbag system is triggered:

Airbag unit, driver's side: 

1. Contact unit.
2. Airbag unit, driver's side.
3. Triggering unit after the system is triggered for the third time.
4. Airbag sensors: see below .

Airbag unit, passenger's side: 

1. Airbag unit, passenger's side.
2. Triggering unit after the system is triggered for the third time.
3. Dashboard.
4. Check dashboard bracket for deformation and replace if necessary.
5. Airbag sensors: see below  1 .

Side airbag unit, seat: 

1. Side airbag unit, seat.
2. Seat covering, deformed seat components.
3. Triggering unit after the system is triggered for the third time.
4. Airbag sensors: see below  1 .

Head airbag unit: 

1. Replace roof lining.
2. Airbag sensors: see below  1 .
3. Triggering unit after the system is triggered for the third time.

Airbag sensor: 

1. All airbag sensors in damaged/deformed areas of the vehicle must always be replaced.
2. Otherwise (i.e. even if the vehicle was not crashed), the airbag sensors must be replaced if they show signs of mechanical damage and/or if the airbag control unit detects that the airbag sensor is defective (use PIWIS Tester II 9818  to read out the fault memory).
3. Triggering unit after the system is triggered for the third time.

Seat-belt pretensioners: 

1. All seat-belt pretensioner units.
2. Triggering unit after the system is triggered for the third time.

Because it is difficult to visually determine if one or more seat-belt pretensioners has been triggered, check the following points: 

• Use PIWIS Tester II 9818  to read out the fault memory.
• Check plug connection on the seat-belt pretensioner for damage.
• Pull out the belt strap as far as possible and check for wear.
• Perform a function test on the automatic belt device.
