Product Information

Volkswagen AC Hoses and Pipes diagram for Q3, Tiguan

An A/C pipe is a metal or rubber line within the air conditioning system that carries refrigerant between components such as the compressor, condenser, evaporator, and expansion valve. It is designed to withstand high pressure and temperature variations while maintaining a sealed refrigerant flow. A properly functioning A/C pipe ensures efficient cooling performance and reliable operation of the vehicle’s climate control system.

• Reduced or no cooling, due to refrigerant leaks.
• Visible cracks, corrosion, or oil stains along the pipe, indicating damage or leakage.
• Hissing sounds or loss of pressure, caused by escaping refrigerant from the pipe.

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.
