Volkswagen Passat B7 Air Conditioning A/C Evaporator 1K2820103E

The Volkswagen Passat B7 Air Conditioning Evaporator is a component of the A/C system responsible for efficient refrigerant evaporation and stable reduction of cabin air temperature. This component, designed for the B7 generation Passat's air conditioning system, ensures proper integration with the factory installation and restores full interior cooling functionality. By utilizing the original Volkswagen design, the correct airflow characteristics and compatibility with the vehicle's factory parameters are maintained.

Purpose and Function in the Air Conditioning System

The Passat B7 Air Conditioning Evaporator operates in the low-pressure part of the A/C circuit, where the refrigerant evaporates and intensely absorbs heat from the air flowing through its fins. A correctly selected evaporator:

• stabilizes the supply air temperature under various thermal loads,
• ensures uniform cooling of the entire cabin,
• works with the factory A/C system components (compressor, condenser, expansion valve),
• limits the risk of air conditioning performance drop at high external temperatures.

By maintaining the original geometry of the flow channels and heat exchange surface, the evaporator preserves the correct balance between cooling efficiency and compressor load.

Compatibility and Fit for Volkswagen Passat B7

The offered component has been specifically designed for the platform used in the Volkswagen Passat B7 model, ensuring a precise fit within the heater housing and air ducts. The Volkswagen brand guarantees compliance with factory installation standards and proper interaction with the air conditioning control electronics.

This precise fit minimizes the risk of leaks, improper condensate drainage, or reduced airflow performance. For workshops, this translates to predictable installation times, and for the user, it means maintaining system operating characteristics close to the factory state.

Performance Characteristics and Benefits of Use

Using an original evaporator in the Passat B7 allows for the restoration of correct air conditioning operating parameters after a failure, leak, or blockage of the old component. In practice, this means:

• more stable supply air temperature during long drives,
• more efficient evaporation of moisture from the cabin air,
• reduced risk of window fogging when the air conditioning is on,
• maintenance of correct operating pressure in the low-pressure part of the system.

A used component with preserved fin structure and flow channels offers a reasonable compromise between repair cost and maintaining the A/C system's factory operating characteristics. The Evaporators Category includes components of crucial importance for thermal comfort, so selecting the right model directly impacts the perceived cooling quality.

Condition, Origin, and Installation Aspects

The offered evaporator comes from the group of parts designated as Volkswagen OE, confirming its factory origin and compliance with manufacturer documentation. The used condition indicates that the component has been previously in use but is still suitable for further use after proper workshop verification. For professional service centers, this provides a good basis for an economical air conditioning system repair while maintaining the original design.

During installation, it is recommended to:

• check the entire system for leaks after installing the evaporator,
• replace the desiccant and perform a vacuum before filling with refrigerant,
• check the drainage of condensate from the heater housing for unobstructed flow.

This approach allows for maximum utilization of the installed component's potential and reduces the risk of further interventions in the A/C system.

If you are planning a comprehensive repair or upgrade of the air conditioning zone in your Volkswagen and need other components from the same group, such as heat exchangers, cooling modules, or additional A/C system components, check the available parts in the Volkswagen Evaporators category.

Additional Information and Knowledge about Used Parts

When selecting used components for German cars, it is beneficial to be aware of best practices related to assessing technical condition, cost-effectiveness of refurbishment, and the impact on the durability of the entire system. An extended discussion of these issues, using Audi as an example, can be found in the article Audi on Second-Hand Parts – Tuning and Repairs Without Quality Loss, which demonstrates how to consciously use used components without sacrificing robustness and operational predictability.
