I'm not looking for a cure, just a temporary way to lift it off its arse. The compressor will hopefully be repaired today and codes cleared tonight but if for some reason the parts dont turm up i cant do another 150 miles on the bump stops till tomorrow night.
Think i read somewhere that the compressor runs but starts buzzing. That maybe a little more than a piston seal needed. The motor itself sounds tired to me if that is the case.
