Core Functions

1. Precisely throttle high-pressure liquid refrigerant into low-pressure atomized mist to realize heat absorption cooling inside evaporator
2. ECU real-time digital adjustment of refrigerant flow rate, eliminate evaporator frosting and airflow blockage under variable load
3. Adapt to dual cooling demand of hybrid powertrain (cabin AC + battery thermal management)
4. Balance AC system high/low pressure to maintain stable cold air output under idle, high-speed and battery charging working conditions
5. Optimize energy efficiency for electric vehicles, reduce power consumption of electric A/C compressor

Common Malfunctions Resolved

• Weak, fluctuating cold air output, intermittent warm airflow
• Severe evaporator ice blockage leading to zero vent airflow
• AC system high/low pressure continuous fluctuation triggering compressor protection shutdown
• HVAC ECU storing refrigerant flow control fault codes
• Slow refrigerant leakage at valve flange sealing surfaces
• Stepper motor failure causing valve stuck fully open / fully closed

Product Advantages

1. Authentic BMW OEM electronic expansion valve, identical internal calibration and control precision as factory original spare parts
2. Digital stepper motor control, far higher flow adjustment accuracy than traditional thermal expansion valves, perfect for hybrid/EV dual cooling systems
3. One-piece aluminum valve body with precision CNC machining, eliminate hidden internal leakage risks
4. Exact OEM flange and mounting layout, no pipe bending or adapters required during dashboard overhaul
5. Heat-resistant integrated sealing O-rings, resistant to softening and leakage under long-term high dashboard temperature exposure
6. Single part covers G20 hybrid, G01 PHEV and i3/i4 pure electric full compatible range, reduce warehouse inventory SKUs

Package Includes

Installation Guidance

1. Fully recover all R134a refrigerant from AC system before disassembling dashboard heater box assembly
2. Disconnect vehicle 12V battery negative terminal to avoid ECU short-circuit damage
3. Replace receiver drier synchronously when overhauling electric expansion valve to filter metal debris inside refrigerant pipelines
4. Maintain vacuum pumping for minimum 60 minutes prior to refilling refrigerant
5. After installation, run HVAC ECU adaptation calibration with BMW ISTA diagnostic scanner
6. Test cooling performance at idle, high speed and battery charging working conditions
