Product Information

Audi AC Hoses and Pipes diagram for A3 Quattro, TT Quattro, TTS Quattro, S3, A3

An A/C refrigerant hose is a flexible, high-pressure line that carries refrigerant between key components of a vehicle’s air conditioning system, such as the compressor, condenser, and evaporator. Because it transports refrigerant in either gaseous or liquid form under varying pressure and temperature, the hose is reinforced with durable rubber and synthetic layers to withstand extreme operating conditions. Its proper function is essential for maintaining the closed loop that enables the A/C system to cool the cabin effectively.

• Weak or no cooling from the A/C due to refrigerant leaks in the hose.
• Oily residue, cracks, or visible damage along the hose, sometimes accompanied by a hissing sound.
• Frequent compressor cycling or A/C system shutdown caused by pressure loss.

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.
