Product Overview

The A/C compressor, OEM number 3W0820803, is a Denso 7SEU16C-type unit fitted to VW and Audi models sharing this compressor design, including the Touareg, Q7, A6, and A8. Since this compressor cross-references to several closely related VW Group part numbers used across the same shared platform, it's a useful part number for distributors serving VW and Audi A/C parts demand.

Worn or failing units typically show up as weak or no cold air, unusual noise from the compressor, or a refrigerant leak. GSK Auto manufactures this compressor to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an A/C Compressor?

Function: The A/C compressor pressurizes refrigerant gas and circulates it through the air conditioning system, enabling the system to cool cabin air.

Working Principle: Driven by the engine via a belt and pulley, the compressor draws in low-pressure refrigerant gas and compresses it into a high-pressure gas, which then flows to the condenser to begin the cooling cycle.

Importance: On VW Group's shared V6 platform, a reliable A/C compressor is essential for cabin comfort and consistent system performance across daily use.

Common Failures & Signs: Internal seal or shaft wear causing refrigerant leaks. Worn clutch or bearing causing noise or clicking from the compressor. Weak, warm, or inconsistent cooling. Compressor clutch failing to engage.
