Audi Rain Sensor - Genuine Audi 81A955547B

Product Information

A rain sensor is an electronic device typically mounted on the windshield behind the rearview mirror that detects moisture levels on the glass. It automatically activates and adjusts the speed of the windshield wipers based on rainfall intensity, improving visibility and driver convenience. By responding in real-time to changing weather conditions, the rain sensor enhances safety and reduces the need for manual wiper control.

• Wipers not activating automatically, even when rain is present.
• Erratic or overly sensitive wiper operation, caused by faulty sensor readings.
• Warning light or diagnostic trouble code, indicating a malfunction in the sensor system.

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.
