Audi A/C Refrigerant Suction Hose - Genuine Audi 4M0816743AC

Product Information

An A/C refrigerant suction hose is a flexible hose in a vehicle’s air conditioning system that carries low-pressure refrigerant from the evaporator (inside the cabin) back to the compressor. It’s part of the closed-loop refrigerant circuit and is designed to handle low-pressure, low-temperature refrigerant in gas form.

These hoses are usually made of reinforced rubber or synthetic materials with metal fittings at each end to withstand pressure changes and vibration.

• Reduced Cooling Performance: The A/C may blow warm or less cold air due to refrigerant loss or restricted flow.
• Hissing or Bubbling Noise: A refrigerant leak in the hose can cause audible hissing when the system is running.
• Visible Refrigerant or Oil Leaks: Refrigerant often carries a small amount of oil; oily residue or wet spots around hose connections can indicate failure.

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.
