Audi Air Bag Impact Sensor - Genuine Audi 4N0959651E

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 Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi 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 Audi parts box and find an OEM branded part inside, simply with the addition of an Audi 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.
