Does anyone know of a good diesel specialist in the NE of Melbourne?
My patrol (3.0 crd) is blowing black smoke. I don't notice it from the cab except when taking off on a hill but people following me on trips all mention it.

I am am not sure if the injectors are on the way out or if it's caused by the remap l had done 3 years ago. Engine has done 180,000 km and the boost is fine (15-18 psi). The car runs well but not very clean.
