Discharge refrigerant circuit

WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. 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 is rather to be extracted from the refrigerant circuit using an extractor or service station. The refrigerant removed is then either to be reprocessed on site or returned to the manufacturer for proper disposal (different or additional regulations may apply in other countries). → 87 - AIR CONDITIONING

Reason:

Should it escape into the earths atmosphere, refrigerant R134a will have a detrimental effect in terms of global warming.

NOTE:

Refrigerant R134a has far less of a greenhouse effect than R12.
The refrigerant R134a does not affect the ozone layer in the earths atmosphere (R134a is an H-FC with no chlorine atoms). 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).

After discharging the air conditioner, disconnect the connector from the A/C Compressor Regulator Valve N280 or from the High Pressure Sensor G65.

Reason:

The A/C Compressor Regulator Valve N280 is then no longer activated and the compressor runs at idle. The compressor is designed such that lubrication of the compressor components is guaranteed by way of an internal oil circuit at idle (provided there is sufficient refrigerant oil in the compressor).
