OE-Style A/C Condenser for BMW Cooling Repair

Restore proper air conditioning performance with this OSC Premium New Automotive A/C Condenser, Part Number 3105. Built for Original Equipment form and function, it is designed for BMW applications that need reliable heat rejection, accurate fitment, and straightforward replacement.

This condenser uses aluminum construction with a parallel flow design to support efficient heat transfer in demanding HVAC systems. It is engineered for BMW 525i, 530i, 545i, 645Ci, 745i, 745Li, 750i, 750Li, 760i, 760Li, 525xi, 530xi, 528xi, 550i, 650i, M5, and M6 applications across model years 2002-2010.

Key Features

• Designed to Original Equipment form and function
• Parallel flow aluminum construction for efficient heat dissipation
• Extruded condenser tubes for structural integrity
• Louvered aluminum fins and tubes joined with furnace-brazed construction
• Individually pressure tested for quality verification
• Block fitting inlet and outlet connections
• Drier included
• Engineered for multi-fit without compromising appearance or performance

Detailed Description

OSC Part Number 3105 is a premium replacement A/C condenser built to match OE-style dimensions and cooling requirements. The core measures 24 1/2 inches wide by 16 9/16 inches long with a 5/8-inch core thickness, and the parallel flow layout is suited to efficient refrigerant cooling. Aluminum construction, brazed tube-and-fin assembly, and extruded tubes help maintain durability and thermal performance in BMW HVAC systems.

This condenser cross-references APDI 7013105 and Spectra Premium 7-3105 for the same application. It is a direct-fit solution for BMW 525i, 530i, 545i, 645Ci, 745i, 745Li, 750i, 750Li, 760i, 760Li, 525xi, 530xi, 528xi, 550i, 650i, M5, and M6 models where the original condenser has failed or cooling efficiency has dropped. Part Number 3105 is built for accurate replacement without altering the vehicle’s factory HVAC layout.

Common Problems This Part Can Address

• Weak cabin cooling from a leaking or restricted condenser
• Refrigerant loss caused by damaged condenser tubes or fittings
• Reduced A/C performance from poor heat transfer
• Corrosion or physical damage to the front-mounted condenser assembly
• Fitment issues when replacing an OE-style BMW condenser

Installation Notes and Tips

Verify inlet and outlet block fittings before installation and compare the new condenser to the original unit for core size and mounting alignment. Replace any contaminated refrigerant system components as needed, and evacuate and recharge the system according to BMW service procedures after installation. Because this unit includes a drier, confirm the rest of the A/C system is clean and free of debris before final assembly.

Quality Assurance

Each OSC condenser is individually pressure tested before release to help confirm sealing integrity and consistent performance. The furnace-brazed aluminum construction is used to support heat dissipation and long-term durability in automotive HVAC service.
