Audi Door Mirror - Genuine Audi 4K8857409S9B9

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 Audi

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

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