Volkswagen Golf Owners Manual: Repairs and faults in the airbag system

First read and observe the introductory information and safety warnings 

Repairs and 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 can be located 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 tyre/rim combinations that have not been approved by Volkswagen, lowering the vehicle, making modifications to the suspension rate including work on the springs, struts and shock absorbers 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. 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.

• Repairs and modifications to your vehicle should only be carried out by a qualified workshop.

• Airbag modules cannot be repaired. They must be replaced.

• Never use 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 any components in the suspension system that do not have the same characteristics as the original factory-fitted components.

• Never use tyre/rim combinations that have not been approved by Volkswagen.
