Hi. After resolving a myriad of issuettes with my TD4 it passed its MOT today. The mechanic said that it passed the emission test but in his view was running quite rich.
The car has never used so much as a drop of engine oil between services whilst I have owned it, but there has always been a smell of unburnt fuel and smoke coming out, much worse on idle, that is blue and as I said, it isn't the engine oil as it hasn't ever lost any!
I was tempted to change the MAF Sensor as I have already swapped the old Crankcase Breather with the centrefugal BMW unit.....does anyone have any idea what I might do to stop the rich running?
