VW Door Mirror Glass - Genuine VW 5K0857521A

Product Information

The door mirror glass is the glass surface on a vehicle’s side mirror, allowing drivers to see behind and beside them. It’s an essential safety component for visibility and situational awareness when driving, changing lanes, or parking. Door mirror glass can be electrically heated to prevent fogging and ice buildup. They are sometimes convex to provide better visibility and allow for a wider range of visibility around the vehicle for the driver.

• Cracked or Broken Glass: Physical damage, such as cracks or shattering, makes it difficult to see clearly, impairing visibility
• Electrical Malfunction: In vehicles with electrically adjustable mirrors, failure of the mirror motor can prevent the glass from adjusting properly, affecting optimal positioning for the driver

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.
