Signs Your BMW Expansion Valve or Receiver Drier Needs Replacement

• Temperature swings: AC blows cold at first, then warm, or some vents cold while others warm.
• AC not reaching low temperature, or system takes longer than usual to cool down. — could be expansion valve not metering correctly.
• High-side pressure abnormal, or low-side pressure too high (indicating restriction) or too low (indicating undercharge or closed valve).
• AC performance drops after driving for a while; evaporator icing or frost, or signs of moisture or smell (from saturated receiver drier).
• Visible leaks, rust or damage on receiver/drier casing, or clogging particles showing up during system servicing.

FAQs

What happens if the expansion valve is stuck closed?

If it’s stuck closed, coolant flow is severely restricted and evaporation in the evaporator core will drop, causing poor cooling or no cooling. Pressures may read abnormally low on the low side.

Can I just replace the receiver drier alone?

Yes, if the receiver/drier is the only faulty component. But often when a drier fails, there is moisture, debris or contamination in the system that also affects the valve or other parts. Replacing both together is safer and more reliable.

How do I avoid problems with moisture in the AC system?

Make sure the system is properly evacuated when opened, replace the receiver drier, use proper desiccant inside, check for leaks, and avoid letting refrigerant run low. Moisture leads to corrosion and reduced AC efficiency.

How to pick correct expansion valve and drier for my BMW?

Use your vehicle’s VIN via the Garage Tool. That ensures correct orifice size, refrigerant compatibility, and connections. Matching specs prevents airflow problems, poor cooling or damage to other AC components.
