Audi VW Air Bag Impact Sensor - Genuine Audi VW 4N0955557A

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 VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

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