BMW E90 E87 E84 A/C Compressor 64529182793 - Used Original Parts

Diagnosis and Common Symptoms

A failing A/C compressor on the BMW E90, E87, and E84 chassis typically presents with warm air blowing from the vents despite the compressor clutch engaging normally. Drivers often report a loud grinding, squealing, or knocking noise from the front of the engine bay, particularly when the A/C is switched on, indicating worn internal bearings or seized pistons within the compressor body. In more advanced cases, the compressor clutch may fail to engage at all, triggering a Check Control message related to A/C system malfunction. Refrigerant leaks around the compressor shaft seal are also common, leading to a gradual loss of cooling performance and, in some cases, visible oil residue on the compressor housing itself.
