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.

CAUTION:

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

Only use tools and materials approved by the manufacturer.

The warranty is void 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 refrigerant circuit components. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .

NOTE:

Until now, the following replacement parts (A/C compressor, reservoir, evaporator and condenser) were filled with nitrogen gas. This filling is being gradually discontinued. Therefore little or no pressure equalization is noticeable when unscrewing plugs from replacement parts.
