Audi Sunroof Motor - Genuine Audi 4G8959591A

Product Information

The sunroof motor is an electric drive unit that powers the opening, closing, and tilting functions of a vehicle’s sunroof assembly. Controlled by interior switches or the vehicle’s body control module, the motor engages gears and cables to move the sunroof glass smoothly and securely. Built for durability and frequent use, the sunroof motor is typically compact, sealed against moisture, and engineered for quiet, reliable operation.

• Sunroof will not open, close, or tilt – caused by a completely failed motor.
• Slow, jerky, or incomplete sunroof movement – indicates weakening motor performance.
• Clicking, grinding, or buzzing noises – caused by worn internal gears or motor strain.

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.
