Hi everyone Anyone here rebuild VIR before? cleaning POA valve and expansion valve is enough or I only should change them? That big muffler on compressor hose was rusted inside and rust particles find their way to VIR, I disassembled it and want to clean it properly. Also bought a new A6 compressor and should clean radiator, evaporator and hoses too. another thing is installing VIR eliminator. are they work better or worse than original VIR?
