First thing in morning I get a cloud of dirty smoke (not blue) from my 3.0 tdi Is this indicative of failing injectors or pump? No codes apart from left engine mount. Had 2 bad glowplugs but replaced them. Did have a maf code other day but hasn't returned. Are there any pump pressure or injector figures to compare? On blocks for injectors only 1 seems a bit low .47mg. Cheers guys.
