Audi VW Ignition Starter Switch - Genuine VW Audi 1K0905849B

Product Information

An ignition switch is a component in a vehicle’s electrical system that initiates the engine’s start-up sequence and provides power to the vehicle’s accessories. It’s typically located on the steering column or dashboard and works in conjunction with the ignition cylinder, activated when you turn the key or press the start button. The ignition switch has multiple positions, including "Off," "Accessory," "On," and "Start," each supplying power to different vehicle functions.

• Failure to Start: One of the most common symptoms is the engine failing to start or cranking intermittently, as the switch may not properly supply power to the starter motor or ignition system
• Accessory Power Loss: Accessories like the radio, headlights, or power windows may fail to work or may turn off unexpectedly, even when the ignition is in the "On" or "Accessory" position

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.
