WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

In the right state refrigerant R1234yf is chemically stable and does not damage iron, aluminum and corresponding developed and suitable plastic. Mixing refrigerant oil and refrigerant R1234yf can damage specific metals (for example alloys with copper) and can damage and dissolve specific hose materials and plastics. For this reason use only original parts. Refer to the Parts Information.
Make exclusive use of components which are resistant to refrigerant R1234yf and the related refrigerant oils. Do not use any components (such as seals and hoses that are made of plastic) which were not clearly assigned. Refer to the Parts Information.
The pipes and the hoses are held together with bolts or by special connections. Refer to REFRIGERANT CIRCUIT - 1 , REFRIGERANT CIRCUIT - 2 , REFRIGERANT CIRCUIT 1234yf - 2 , REFRIGERANT CIRCUIT GENERAL INFORMATION R134a , REFRIGERANT CIRCUIT R134a .
Replace the sealing components (for example seals) between the components. Refer to the Parts Information.
Note the tightening specification on threaded connections, for connectors use the corresponding release tools.
