US/LHD 325i sedan M54 only. BMW catalog wording uses both till and from 200209, so a September 2002 car requires VIN/build lookup plus the installed compressor manufacturer/model/number, ports, connector and pulley. Read the underhood refrigerant label and exact compressor oil/precharge instructions. Diagnose leak/charge, clutch command, electrical control, belt, airflow and system pressures before ordering. Recover refrigerant legally. Internal compressor damage requires contamination assessment, drier replacement and expansion-valve inspection rather than an assumed compressor-only repair.

Fitment
US/LHD 325i sedan M54 only. BMW catalog wording uses both till and from 200209, so a September 2002 car requires VIN/build lookup plus the installed compressor manufacturer/model/number, ports, connector and pulley. Read the underhood refrigerant label and exact compressor oil/precharge instructions. Diagnose leak/charge, clutch command, electrical control, belt, airflow and system pressures before ordering. Recover refrigerant legally. Internal compressor damage requires contamination assessment, drier replacement and expansion-valve inspection rather than an assumed compressor-only repair.
Aftermarket options
Checked paths include Genuine BMW early and late compressors, DENSO 7SBU16C application references, Mahle/Behr, Nissens and Topran receiver-driers, and Nissens/OE-supplier expansion valves. DENSO DCP05014/64526910458 and DCP05039/64526916232 overlap in broad application data; that does not override BMW VIN/build selection or prove universal interchange. Compressor-only listings do not include every seal, drier, valve, flush, evacuation, oil-accounting or recharge requirement.
Before you buy
US/LHD 2001-2005 325i sedan M54 only. September 2002 is a catalog boundary; verify VIN/build and the installed compressor label, ports, connector and pulley. The underhood refrigerant label and current OE oil procedure control. Recover refrigerant legally and diagnose leak, electrical/clutch and contamination scope before ordering. Prices and seller timing are dated snapshots; a compressor alone may be an incomplete repair.
