A/C Service Station, Important Usage Information

WARNING: This page is about a different car, the 2024 Audi SQ7, 2024 Audi Q7, 2023 Audi SQ7, and 2023 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

Observe the following with regard to A/C service station operation. Refer to the appropriate Electronic Parts Information (Tools; Special Tools and Equipment: A/C and Heating).

-- The installed filters and dryers must be replaced, at the latest, when the service life specified in the relevant operating instructions has been reached.

-- If an A/C service station is also used for cleaning (flushing) the refrigerant circuit, the installed dryer and filter must be replaced in shorter intervals. Refer to REFRIGERANT CIRCUIT, CLEANING WITH COMPRESSED AIR AND NITROGEN .

-- Only refrigerant oils that have been approved for the refrigerant circuit in that vehicle may be added (if necessary, fill the refrigerant oil directly into the refrigerant circuit). Refer to the appropriate Electronic Parts Information.

Extracted refrigerant is not to be reused if there is any doubt about the composition of the refrigerant extracted, even after cleaning in the A/C service station.

-- The A/C service station is to be discharged in these cases (Refer to A/C SERVICE STATION, CONNECTING ). The system is cleaned if necessary, and the filters, dryers and refrigerant oil are replaced.

-- For example, within Germany, contaminated refrigerant can be returned to the supplier in recycling containers for recycling or for environmentally safe disposal. Other or additional regulations may apply in other countries.

Commercially available A/C service stations can be classified in two groups:

A/C service stations that clean extracted vehicle refrigerant for re-use (so-called extraction and recycling stations). For currently available A/C service stations, refer to the appropriate Electronic Parts Information (Tools; Special Tools and Equipment: A/C and Heating).

A/C service stations that transfer extracted refrigerant to recycling containers (for large-scale recycling). These are referred to as extraction systems.
