Airbags

Airbags are one of the most important passenger protection systems in modern cars. Their task is to minimize the risk of injury during a collision by absorbing the force of the impact. Properly functioning airbags increase the safety of the driver and passengers, providing additional protection in emergency situations. In the Global Parts automotive store, you will find a wide selection of used car parts, including airbags, perfectly matched to brands such as BMW, Audi, Mercedes, Volkswagen, Mini, and others.

What functions do airbags perform?

Airbags are an integral part of vehicle safety systems:

• Impact force absorption – In the event of a collision, airbags deploy rapidly, minimizing injuries to the driver and passengers.
• Protection of key body parts – They protect the head, chest, knees, and other sensitive areas.
• Integration with vehicle systems – They work in conjunction with seat belts, crash sensors, and ESP and ABS systems, increasing the effectiveness of protection. Used auto parts, such as airbags, allow for the cost-effective restoration of the full functionality of the safety system.

Construction and purpose of airbags

Airbags are passive safety system components mounted in the steering wheel, dashboard, seats, pillars, or headliner. A typical set consists of an airbag module, housing, gas generator, and an electrical connector that works with the vehicle's wiring. Their design and placement vary depending on the mounting side, body version, and vehicle equipment. When completing a repair for a specific model, e.g., BMW E90, it is worth comparing the OEM number, plug type, and mounting location.

Comparison of airbag variants

Airbag type	Mounting location	Cooperating elements	What to check before selection
Driver	Steering wheel	Clock spring, SRS controller, steering wheel cover	OEM number, connector type, compatibility with steering wheel version
Passenger	Dashboard	Dashboard, mounts, SRS controller	Dashboard version, mounting points, OEM part number
Side	Seat backrest or door panel	Upholstery, seat frame, wiring harness	Mounting side, seat compatibility, body type
Curtain	Pillar and headliner	Headliner, pillars, SRS controller	Body version, module length, mounting points

Why is it worth taking care of airbags?

Regular inspection and replacement of faulty airbag system components is the basis of safety. Typical problems include:

• Control module wear – This can cause delays in airbag activation, which affects their effectiveness.
• Damaged crash sensors – Sensor failure can prevent them from working properly.
• Deployed or damaged airbags – After activation, they require replacement with new or high-quality used car parts. If a replacement is needed, choose car parts that are thoroughly checked and suitable for reuse.

The role of the controller and cooperating elements

The SRS controller is a module that manages signals from sensors and decides on the activation of airbags. It is used to analyze a collision and trigger the correct circuit at the right time, which is why it must be compatible with the vehicle's wiring and equipment. When choosing a component such as an Audi A6 C7 steering wheel, you need to verify the compatibility of the airbag, buttons, and connector, as these components work as one system. In practice, the selection should also be supplemented by checking airbag parts and their mounts.

How to choose the right airbags?

• Matching the vehicle model – At Global Parts, you will find airbags perfectly matched to BMW, Audi, Mercedes, Volkswagen, Mini, and others.
• Technical condition – Used airbags should be fully functional, free from damage, and properly stored.
• Compatibility with vehicle systems – Ensure that the airbags are compatible with the control modules and the crash system of your car.
• Type of airbags – Choose the appropriate type, e.g., driver, passenger, side, knee, or curtain. High-quality auto parts, such as used airbags, ensure reliability and safety.

Selection by OEM number and equipment version

The OEM number is the basic manufacturer designation that allows you to compare a part with the vehicle's factory equipment. It is used to confirm the module's compatibility with a specific body version, mounting side, connector type, and interchangeable numbers. If you are looking for a component such as an Audi A3 8P rear bumper, you usually check the mounting points and body version first; for airbags, part numbers, vehicle placement, and equipment compatibility are equally important. It is also helpful to compare elements with the seat belts and parts and cabin safety sections when the repair covers a larger part of the protection system.

How to take care of airbags?

• Regular inspections – During technical inspections, check the operation of the airbags and related systems.
• Sensor control – Ensure that all crash sensors are working properly.
• Replacement of damaged elements – In case of deployment or failure, choose used auto parts that will restore full system functionality.
• Electronics protection – Maintain proper conditions for control modules to prevent damage.

Checking assembly and compatibility after repair

Airbag mounting refers to the set of attachment points, screws, and guides that hold the module in the correct position. It is used to stably seat the part in the steering wheel, dashboard, or seat, and its compatibility affects the proper fit of covers and interior elements. After installation, it is worth checking the position of the wiring, the condition of the connectors, and the compatibility of the placement on the vehicle with the product description.

FAQ

Question	Answer
What is the construction and purpose of airbags?	Airbags are passive safety system components mounted in various interior zones of the vehicle, such as the steering wheel, dashboard, seats, pillars, or headliner. A typical module includes the airbag cover, gas generator, housing, and an electrical connector that works with the SRS controller. Their purpose is to limit the effects of a collision by creating a cushioning zone between the passenger and interior elements.
What are airbags used for?	Airbags are used to reduce the risk of injury during a collision and work in conjunction with seat belts and crash sensors. Their task is to absorb part of the impact energy and limit body contact with the steering wheel, dashboard, windshield, or side body structure. A functional system improves the protection of the driver and passengers depending on the direction of the impact and vehicle equipment.
What is the construction and function of the SRS controller?	The SRS controller is an electronic module that manages the operation of airbags and other passive safety system components. It receives signals from sensors, analyzes collision parameters, and triggers the appropriate circuit at the right moment. Its function also includes recording information about the event and checking the compatibility of individual components with the vehicle's wiring.
How to choose airbags for a specific car?	When choosing, it is worth comparing the OEM part number, interchangeable numbers, vehicle placement, and mounting side. The body version, interior type, and equipment are also important, as the same car model may have different module variants. A good practice is to verify by VIN or compare the old part with photos and the product description.
What symptoms indicate a problem with the airbag system?	The most common signal is the safety system warning light on the dashboard, errors saved in the controller, or a lack of compatibility after interior repairs. Problems can also be caused by damaged connectors, sensors, the clock spring, or an incorrectly selected module. In such a situation, you need to check not only the airbag itself but also the cooperating elements.
What data should be paid attention to before installing an airbag?	Before installation, you should verify the OEM number, housing condition, mounting type, connector compatibility, and the location intended for the part. It is also worth checking whether the module corresponds to the pre-facelift or post-facelift version, the vehicle side, and cabin equipment. Such a comparison makes it easier to seat the part correctly and avoid problems with the fit of covers and wiring.
