Refrigerant Circuit, Cleaning

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

Clean the refrigerant circuit with refrigerant R134a (flush with refrigerant R134a) (refer to Refer to REFRIGERANT CIRCUIT, CLEANING (FLUSHING) WITH REFRIGERANT R134A ) or blow out with compressed air and nitrogen (refer to Refer to REFRIGERANT CIRCUIT, CLEANING WITH COMPRESSED AIR AND NITROGEN ) if:

-- Moisture or dirt has gotten into the refrigerant circuit (after a collision for example).

-- Refrigerant oil is dark and viscous.

-- There is too much refrigerant oil in the refrigerant circuit after replacing the compressor.

-- The A/C compressor had to be replaced due to "internal" damage (for example, noises or no output).

NOTE:

When cleaning components with compressed air and nitrogen, always extract the gas mixture escaping from the components through a suitable exhaust extracting system (workshop extraction system).
