Refrigerant Circuit Components

WARNING: This page is about a different car, the 2022 Audi S3, 2022 Audi RS 3, 2022 Audi A3 Quattro, and 2022 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Non-approved tools or materials such as leak sealing additives can cause damage or malfunctions in the system.

Only use tools and materials approved by the manufacturer.

The warranty is voided if non-approved tools or materials are used.

Any refrigerant circuit components submitted for quality observation must be sealed (use the caps that come with the replacement part).
Replace damaged or leaking components of the refrigerant circuit. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .

NOTE:

To date, the following replacement parts (A/C compressor, reservoir, evaporator and condenser) are filled with nitrogen gas. This charge is being gradually discontinued. Little or no pressure equalization is therefore noticeable on unscrewing sealing plugs from replacement parts.
