Audi A/C Hose Assembly - Genuine Audi 4K1816740AE

Product Information

An A/C hose assembly is either a high- or low-pressure hose that carry refrigerant between the main components of the air conditioning system, such as the compressor, condenser, evaporator, and expansion valve. These hoses are designed to withstand both high pressure and temperature variations while keeping the refrigerant sealed within the system.

• Refrigerant leaks, often seen as oily residue or detected by reduced cooling performance.
• Weak or no cold air from the A/C system due to loss of refrigerant pressure.
• Hissing noises or visible cracks in the hoses, especially under high A/C load.

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.
