Cm870 compressor
Is there any way to get the compressor to stop knocking? I’ve got a 2007 kw w900 with a cummins 870 and all you hear is the compressor constantly knocking. Had an 871 and it never sounded that way.
Also looking at some help with ecm. It’s be demandated but by previous owner. Would like to be tuned right. I’ve sent a pm to unilevers but haven’t received a response
