Repairs and faults in the airbag system
Repairs and technical modifications must always be carried out according to Volkswagen
specifications →
.
Modifications and repairs to the front bumper, the doors, the front seats, the headliner, or the
bodywork should be carried out by a qualified workshop. System components and airbag system
sensors might be fitted on these vehicle components.
If you work on the airbag system or remove and install parts of the system when performing
other repair work, parts of the airbag system may be damaged. The consequence may be that, in
the event of an accident, the airbag inflates incorrectly or does not inflate at all.
Regulations must be observed to ensure that the effectiveness of the airbags is not reduced and
that removed parts do not cause any injuries or environmental pollution. Qualified workshops are
familiar with these requirements.
Any modifications to the vehicle's suspension could prevent the airbag system from working
properly during a collision. For example, using wheel rim/tyre combinations that have not been
approved by Volkswagen, lowering the vehicle or making modifications to the suspension rate
including work on the springs, struts and shock absorbers etc., could change the forces that are
measured by the airbag sensors and sent to the electronic control unit. Some changes to the
suspension could cause the forces measured by the sensors to increase, for example. This can
lead to the airbag system being triggered in collision scenarios where it normally would not be
triggered if modifications to the suspension had not been made. Other modifications can cause
the forces measured by the sensors to decrease, therefore preventing the airbag system from
being triggered when it should have been.
WARNING
Incorrect repairs and modifications can cause function problems and damage to the vehicle and
impair the effectiveness of the airbag system. This can result in accidents and serious or even
fatal injuries.

●
Have repairs and modifications to your vehicle carried out only by a qualified workshop.
Airbag modules cannot be repaired. They must be replaced.
Never install recycled airbag components or components that have been taken from end-of-
life vehicles in your vehicle.
WARNING
Modifications to the vehicle's suspension, including the use of unsuitable tyre/rim
combinations, can cause the airbag system to work differently and increase the risk of serious
or fatal injuries in the event of an accident.
●
Never install components in the suspension system which do not have the same
characteristics as the original factory-fitted components.
●
Never use wheel rim/tyre combinations that have not been approved by Volkswagen.
