Product Overview

The AC compressor, OEM number 64527945825, is fitted across the BMW 5 Series (G30, G31), 6 Series Gran Turismo (G32), and 7 Series (G11, G12), covering a wide engine range including the 520d, 520i, 525d, 530d, 530i, 540i, 630d, 630i, 640i, 725d, 730d, 730i, 740i, and 750i, spanning model years 2014-2020. Since this compressor covers three model series and an unusually wide range of engine variants, it's a genuinely high-turnover part for anyone stocking BMW AC system components.

Worn or failing units typically show up as reduced or no AC cooling, unusual noise from the compressor when the AC is engaged, or a compressor that fails to cycle at all. 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.

(Confirm against your VIN or chassis code before ordering - this compressor spans a wide range of engine variants across three model series, so it's worth double-checking the exact chassis and engine before ordering at volume. When replacing the compressor, the dryer should also be replaced and the system flushed, or warranty coverage may not apply.)

What Is an AC Compressor?

Function: The AC compressor pressurizes refrigerant gas, turning it from low-pressure vapor into high-pressure gas that then flows to the condenser to release heat and be converted back into a liquid.

Working Principle: Driven by the engine's serpentine belt, the compressor's internal mechanism compresses low-pressure refrigerant vapor from the evaporator into high-pressure gas, which continues through the AC system. This variable-displacement design adjusts compression levels based on actual cooling demand rather than running at a fixed output.

Importance: The compressor is the core mechanical component of the AC system, and without it functioning correctly, no cooling cycle can take place regardless of the condition of other AC parts.

Common Failures & Signs: Internal wear or seizure causing reduced or no AC output. Unusual noise, such as grinding or clicking, when the AC is engaged. Refrigerant leaks at the compressor shaft seal. Compressor failing to engage or cycle at all.
