Product Information

BMW AC Hoses and Pipes diagram for 550i, 650i, M5

An A/C refrigerant discharge hose is a high-pressure hose that connects the air conditioning compressor to the condenser in a vehicle’s A/C system. After the compressor compresses the refrigerant gas, the discharge hose carries this hot, high-pressure refrigerant to the condenser, where it is cooled before circulating through the rest of the system. Because it handles both high pressure and high temperature, it is made of reinforced rubber or synthetic materials to withstand demanding conditions.

• Weak or no cooling from the A/C due to loss of refrigerant pressure from leaks in the hose.
• Visible refrigerant oil residue or cracks along the hose, sometimes accompanied by a hissing sound.
• A/C system warning lights or compressor cycling frequently because the system cannot maintain proper pressure.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

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