Audi Emissions diagram for Q3 Quattro, CC, Tiguan, Tiguan Limited, Q3, & more

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 VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG 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 VAG parts box and find an OEM branded part inside, simply with the addition of a VAG 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.
