Volkswagen Golf Service & Repair Manual: Renewing pyrotechnic, electrical and mechanical components of the restraint
system after an accident
| Special tools and workshop equipment
required |
| |
Vehicle diagnostic tester |
 Note
-
| |
The airbag control unit can be used for up to 2 side
airbag and/or belt tensioner deployments with the airbag
generation 8.* »not 8.R«. |
-
| |
The airbag control unit can
be used for up to 2 deployments of side airbag/driver
airbag/front passenger airbag and/or belt tensioner with the
airbag generation 9.*, 10.* and 8.R. |
-
| |
After the third deployment, the error message
“Control unit faulty” is displayed. |
| The airbag control unit must be renewed: |
-
| |
In the event of a driver/front passenger airbag
deployment “though not for airbag generation 9.*, 10.* and
8.R ”
→ Anchor |
-
| |
After 3 deployments of side airbag/driver airbag/front
passenger airbag and/or belt tensioner |
-
| |
In the event of damage to the housing |
-
| |
In the event of a deformation to the tunnel within a 200
mm radius of the control unit |
| Always renew the following: |
-
| |
All triggered airbag units. |
-
| |
Battery isolation igniter -N253- |
| Additionally, in the event of the front passenger airbag
being triggered: |
-
-
| |
Supports of front passenger airbag unit which have been
bent out of shape (must not be bent back into shape) |
-
| |
All sensors for front airbag at front end |
-
| |
Remaining sensors for lateral acceleration in event of
deformation of attachment points in vicinity of sensors |
| Additionally, in the event of the driver airbag being
triggered: |
-
| |
Return spring with slip ring |
-
| |
All sensors for front airbag at front end |
-
| |
Remaining sensors for lateral acceleration in event of
deformation of attachment points in vicinity of sensors |
| Additionally, in the event of the side airbag being
triggered: |
-
| |
Pressure sensors on the triggered side |
-
| |
Lateral acceleration sensors on the side affected |
-
-
-
| |
In case of foldable backrest: side padding (if fitted) |
-
| |
Remaining sensors for lateral acceleration in event of
deformation of attachment points in vicinity of sensors |
-
| |
All belt inertia reels with triggered belt tensioners |
-
| |
All belt inertia reels with triggered belt tensioners |
-
| |
Belt buckles for all belt inertia reels with triggered
belt tensioners and seat belt engaged |
-
| |
Belt height adjuster (mechanical and electrical) for all
belt inertia reels with triggered belt tensioners and seat
belt engaged |
| – |
If you suspect that belt tensioners or belt force limiters
have been triggered, connect a vehicle diagnostic tester. |
| – |
Under “15 - Airbag” in »Guided Fault
Finding« check whether there is a crash entry logged for
the airbag control unit. |
| – |
At the same time check whether the “Resistance too high”
fault is also logged for belt tensioners and/or belt force
limiters. Triggered belt tensioners and/or belt force limiters
have to meet both conditions. “Prerequisite: The airbag control
unit has not yet been renewed”. |
Note
-
| |
The “Resistance too high” fault can also be logged in
the event of a cable break. Under normal circumstances, no
crash entry is then logged. |
-
| |
Depending on the crash intensity, it is possible that
the belt tensioner was triggered but
»NOT« the belt force limiter. Observe notes on
disposal of pyrotechnic components
→ Chapter. |
-
| |
In addition, note the section: Checking seat belts
→ Chapter. |
|
|
|
| |
Deployed belt force limiters can be identified by the
following features: |
| |
The pin -1- and lug
-3- have popped out of the belt
force limiter housing on the belt inertia reel. |
| |
The strap -2- is no longer
vertical but is pointing diagonally outwards. |
| – |
If parts of the belt system are removed because of an
accident, the belt system bolts must be renewed. |
| – |
In addition, the following must also be replaced if
necessary (visual check): all damaged components. |
| – |
After renewing the airbag units or the control unit, affix
stickers (only tear-off strips) to the registration card and
return the registration card to the responsible Sales Centre or
to the Importer for registration. |
|
|
|
The side airbag crash sensors respond to changes in pressure
and must therefore be treated with particular caution. Observe
the following:

All damaged securing parts must always be renewed. It is not
permissible to bend the components back into shape or
»make them fit«
