Hello each and every 1 happy to join your community of professional technicians and do it yourselfers to share experience. I have a 2012 PC600lc-8 serial number k50154 problems I am having with it is it slightly black smoke no load high idle just moving the stick then part way in it start to push heavy black smoke air clearer al new faulty injectors change egr leak fix. I even black the egr to see if it was leaking boots pressure any 1 have experience this kind of symptoms
Check MAP sensor values. It's a combi sensor. It measures intake manifold pressure and temp. It's common failure.
OK thanks I found the problem after I did some intensive search it was a air leak
