Purpose and Compatibility

The air conditioning evaporator has been specifically designed for the BMW E81, E87, E90, E91, E92, and E93 platforms, meaning it fits the HVAC system architecture used in these generations. The OEM design guarantees correct port placement, proper refrigerant flow, and seamless integration with other system components.

By using an original BMW OE solution, the factory cooling characteristics are maintained, and the risk of installation issues or leaks is minimized. This is particularly important in vehicles where consistent air conditioning performance and compliance with service documentation are crucial.

Construction and Role in the Air Conditioning System

The evaporator plays a key role as a heat exchanger in the air conditioning system, where the refrigerant evaporates, lowering the temperature of the air directed into the vehicle's interior. The appropriately designed heat exchange surface and airflow channel geometry allow for efficient cooling while maintaining stable flow.

For BMW E8x and E9x models, it is essential that the evaporator is compatible with the original heater core housing and air duct design. Using the correct BMW OE component facilitates installation, ensures proper sealing, and correct positioning relative to sensors and air control flaps.

Condition, Verification, and Benefits of Choosing BMW OE

The offered air conditioning evaporator is a used part, which translates to a favorable compromise between cost and maintaining the original manufacturer's specifications. This type of component allows for the restoration of air conditioning system functionality when the existing heat exchanger has developed leaks, corrosion, or mechanical damage.

Choosing an original BMW OE evaporator offers several advantages:

• maintaining factory cooling and airflow characteristics,
• seamless fit with the heater core housing and lines without modifications,
• compliance with service documentation and workshop procedures,
• easier future diagnostics due to unambiguous OEM marking.

Selection by OEM Number and Interchange Numbers

The evaporator has a dedicated OEM part number and associated interchangeable numbers, which facilitates unambiguous identification in BMW catalogs and service systems. When selecting a part for a specific vehicle, it is advisable to verify compatibility using the Vehicle Identification Number (VIN) and compare the markings with the removed part to ensure full compatibility with the given equipment version and air conditioning system.
