Audi Vapor Canister Filter - Genuine Audi 8W0201997B

Product Information

A vapor canister filter is part of a vehicle’s evaporative emissions control (EVAP) system, designed to filter air entering the charcoal canister. The charcoal canister stores fuel vapors from the fuel tank and later sends them to the engine for combustion, reducing emissions. The vapor canister filter ensures that only clean air passes through the system, preventing dust and debris from contaminating the charcoal and affecting performance.

• Check Engine Light (CEL) illumination, often due to EVAP system faults.
• Fuel odors around the vehicle, caused by vapors not being properly contained or processed.
• Failed emissions test, as a clogged or damaged filter disrupts proper vapor flow.

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.
