Default tdci smoke at idle

Just wondering if any body experiences pronounced dark smoke from the exhaust at idle. When up it for the rent or loaded up a gear the car has always blown a fair bit of smoke which is consistent with other small diesels but of late there has been a rather large amount at idle. Just wondering if this is normal or if any body can shed any light

I have never had black smoke at idle out of mine. Maybe your injectors are not good or you need to take it for a good run on the open road for it to do a burn off

I also reckon a good run out the road is what you need. The DPF might be getting a tad clogged.

Does the car mainly do round town running? If so, a good highway run for an hour or so will probably sort it.

undo the lower pipe off the intercooler, drain any oil accumulated.

remove and clean EGR.

those are the only two that can cause black smoke at idle... (unless cam jumped a tooth)

Not sure if it is connected but having issues with dpf. Normally 50 50 out of town and around town. The black smoke wad idling before a trip to Sydney which was 3 hrs so should have given it a good clean out but still doing it. Will try the intercooler pipe thing first me thinks

Be really careful what you use to clean the egr. also try cleaning the MAF sensor, but only, ONLY use MAF cleaner on it and be very careful with it. DON'T TOUCH THE WIRE!! Google clean MAF sensor and see how you go
