Refrigerant Circuit, Discharging

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Refrigerant is never to be allowed to escape into the atmosphere, but rather it is to be extracted from the refrigerant circuit using an extractor or A/C service station. The drained refrigerant will be locally recycled or is send to an environment-recycling place to the manufacturer (different or additional laws may apply in individual companies). For this reason, bring vehicle to a workshop that has the necessary tools and in which the work can be performed accordingly by qualified personnel. Refer to A/C SYSTEM, GENERAL INFORMATION .

Reason:

If refrigerant R134a is released into the environment, it enhances the greenhouse effect.

NOTE:

Refrigerant R134a has far less of a greenhouse effect than R12.

Because R-134a does not contain chlorine atoms, the major catalyst in ozone depletion, refrigerant R-134a has no ozone depletion potential. Depletion of the ozone layer in the upper atmosphere is however only brought about by the splitting of carbon-chlorine bonds (as is the case, for example, with refrigerant R12).

Disconnect the connector from the A/C Compressor Regulator Valve -N280- or from the A/C Pressure/Temperature Sensor -G395- after draining the air conditioner.

Reason:

The A/C Compressor Regulator Valve -N280- is no longer activated and the A/C compressor runs in neutral. The A/C compressor is designed so the lubrication of the A/C compressor components at idle is guaranteed by an internal oil circuit (as long as there is enough refrigerant oil in the A/C compressor).
