Replacing Components 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 on driver's side.
3. Triggering unit after the system is triggered for the third time.
4. Airbag sensors: see below See  .

Airbag unit, passenger's side: 

1. Airbag unit on 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 it if necessary.
5. Airbag sensors: see below See  .

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 See  .

Head airbag unit: 

1. Replace roof lining.
2. Airbag sensors: see below See  .
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 > 9818 - PIWIS Tester II  to read out the fault memory).
3. Triggering unit after the system is triggered for the third time.

Seat-belt pretensioner: 

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 belt tensioners has been triggered, check the following points: 

Use > 9818 - PIWIS Tester II  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.
