Audi VW Accessory Power Relay - Genuine Audi VW 4L0907282B

Product Information

An accessory power relay is an electrical component that controls the power supply to various vehicle accessories, such as the radio, power windows, or interior lights. It acts as a switch, using a low-current signal to control a higher-current circuit, ensuring reliable operation without overloading the ignition switch. By managing accessory power, the relay helps improve electrical system efficiency and protects sensitive circuits.

• Accessories not functioning, such as radio or windows failing to power on.
• Intermittent operation of powered components, caused by failing relay contacts.
• Clicking noises or no response from the relay when accessories are engaged.

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.
