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.

Airbag unit, passenger's side:

1. Airbag unit, passenger's side.
2. Triggering unit after the system is triggered for the third time.
3. Instrument panel.
4. Check instrument panel bracket for deformation and replace if necessary.

Side airbag unit, seat:

1. Side airbag unit, seat.
2. Seat covering, deformed seat components.
3. Sensor for the side airbag unit after the side airbag is triggered for the third time.
4. Triggering unit after the system is triggered for the third time.

Head airbag unit, door:

1. Head airbag unit.
2. Check door unit carrier for deformation and replace if necessary.
3. Sensor for the side airbag unit after the side airbag is triggered for the third time.
4. Triggering unit after the system is triggered for the third time.

Belt tensioner:

1. All belt tensioner 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:

• Using the PIWIS Tester 9718  , read out the fault memory.
• Check plug connection on the belt tensioner for damage.
• Pull out the belt strap as far as possible and check for wear.
• Perform a function test on the automatic belt device.
