Environmental Information

WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

Since approximately 1992, the A/C systems in newly manufactured cars have been successively converted to refrigerant R134a. This refrigerant does not contain chlorine and does not deplete the ozone layer.

Until approximately 1992, refrigerant R12 was used for A/C systems. Due to its chlorine atoms, this CFC has a high potential for depleting the ozone layer as well as a tendency to increase the greenhouse effect.

Conversion programs are available for old existing systems filled with the ozone-depleting substance R12. Refer to repair information for A/C Systems with Refrigerant R12 (this repair information is only available in hard copy).

The global warming potential of R134a (Global Warming Potential = GWP) is approximately 1400. For this reason the European commission has made it mandatory that from 01/01/2017 no new vehicles with this refrigerant can be brought onto the market. Refer to Refer to REFRIGERANT R134A ENVIRONMENTAL INFORMATION . Therefore, a refrigerant with a GWP less than 150 is introduced for new vehicles from MY 2016 (for example, refrigerant R1234yf with a GWP less than 5).

For environmental protection reasons, refrigerants must not be released into the atmosphere. Refer to LAWS AND REGULATIONS for laws and regulations.
