BMW Air Bag Module Front Left (528i 540i) - Genuine BMW 72127000009

Product Information

An air bag module is the complete safety unit that houses the airbag cushion, inflator, and housing, typically located in the steering wheel, dashboard, side panels, or seats. In the event of a collision, the inflator rapidly releases gas to fill the cushion within milliseconds, creating a protective barrier between the occupants and hard surfaces of the vehicle. The module is a critical part of the Supplemental Restraint System (SRS) and works together with seat belts to reduce the risk of serious injury during an accident.

• Airbag warning light illuminated on the dashboard, indicating a fault in the system.
• Airbag failing to deploy or deploying improperly during a collision.
• Visible damage, tampering, or loose fitment of the airbag cover or housing.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
