Volkswagen Daytime Running Light Module - Genuine VW 5H0998478D

Product Information

A daytime running light (DRL) module is an electronic control unit that automatically activates the vehicle’s daytime running lights when the engine is running. Its purpose is to enhance visibility during daylight hours, improving safety by making the vehicle more noticeable to other drivers. The module regulates power to the DRLs and may also integrate with other lighting functions, such as headlight dimming or automatic lighting control.

• Daytime running lights not turning on, even when the engine is running.
• Intermittent or flickering DRLs, caused by faulty module operation.
• Check light or warning indicator, alerting the driver to a lighting system malfunction.

About Genuine VW

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

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly 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.
