Audi Door Plug - Genuine Audi N90908501

Product Information

A door plug is a small sealing component used to cover access holes or openings within a vehicle’s door structure. It helps keep out water, dust, and debris while also reducing noise and preventing corrosion inside the door cavity. In some cases, door plugs also provide access for service or assembly, making them both functional and protective.

• Water leaks or moisture buildup inside the door panel.
• Increased wind noise due to gaps left by missing or loose plugs.
• Visible missing, cracked, or deteriorated plugs, reducing sealing effectiveness.

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.
