Mercedes Sprinter A/C Expansion Valve – OEM Egelhof | #2308300184 (2010–2018)

A faulty A/C expansion valve is one of the most common causes of weak or inconsistent cooling in your Sprinter — and one of the easiest to overlook. When this valve fails, refrigerant flow becomes unregulated, and your A/C system either freezes up or can't cool at all. This OEM Egelhof replacement restores precise refrigerant metering and gets your climate control working as designed.

What This Part Does

The expansion valve sits between the high-pressure and low-pressure sides of the A/C system, regulating the flow of refrigerant into the evaporator. It controls exactly how much refrigerant enters the evaporator at any given time, which determines how efficiently the system cools the cabin. Too much or too little flow and the whole system loses efficiency — or stops working entirely.

When to Replace It

Replace this valve if you're experiencing inconsistent A/C cooling, ice buildup on the evaporator, warm air from the vents despite the compressor running, or after any A/C system repair involving the evaporator or refrigerant circuit.
