Audi Evaporative Emissions System Lines - Genuine Audi 8W0201991AC

Product Information

Evaporative emissions system lines are the network of hoses and tubes that carry fuel vapors from the fuel tank to the charcoal canister and then to the engine intake for combustion. Their purpose is to prevent raw fuel vapors from escaping into the atmosphere, reducing pollution while improving fuel efficiency. These lines are part of the vehicle’s EVAP system, which is designed to capture and recycle vapors safely, ensuring compliance with emissions regulations.

• Strong smell of fuel around the vehicle caused by vapor leaks.
• Check Engine Light illuminated with EVAP-related diagnostic codes.
• Failed emissions testing due to the system’s inability to contain vapors.

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.
