Just a little part, but it can make a huge difference.
If you don't recognize what this is, don't feel bad—it's a refrigerant control valve from the variable displacement A/C compressor on a 2013 Volkswagen Golf.
Most modern manufacturers have moved away from traditional clutch-cycling compressors and now use variable displacement compressors. Instead of constantly cycling the compressor on and off, these compressors continuously adjust the swash plate angle internally to vary how much refrigerant they pump. The refrigerant control valve regulates that process, allowing the system to maintain more consistent vent temperatures while reducing engine load and improving fuel economy.
Like any electronic or mechanical component, though, these control valves can fail. When they do, the A/C may cool intermittently, stop cooling altogether, or perform inconsistently. While replacing the entire compressor is one repair option, if the compressor itself is still mechanically sound, replacing just the refrigerant control valve is often a much more cost-effective solution.
That's exactly what we did on this 2013 Volkswagen Golf, and now it's back to blowing ice-cold air.
With the Missouri heat we've been having lately, it always seems like this is when the phones start ringing with A/C repair requests. If your import needs A/C diagnostics or repair—whether it's a Subaru, Toyota, Honda, Volkswagen, Audi, BMW, Mercedes-Benz, Volvo, or another foreign vehicle—give us a call or schedule an appointment through our website. We'll help get you back to staying cool.
