BMW Impact Sensor Left (525i 545i 530i 645Ci) - Genuine BMW 65776974364

Product Information

An Air Bag Impact Sensor (also called a crash sensor or airbag sensor) is a safety device in a vehicle that detects sudden deceleration or impact during a collision. It sends a signal to the Airbag Control Module (ACM), which then triggers the airbag deployment to protect occupants.

• Airbag warning light on the dashboard – most common symptom; indicates a fault in the airbag system.
• Airbags may not deploy in a crash – a dangerous failure, as the sensor won’t send the deployment signal.
• Airbags deploy unexpectedly – rare, but possible with a faulty or shorted sensor.

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.
