Early Dodge 6.7L CTD, EGR and Turbo Issues
Hi all, I have a 2007 Dodge Mega cab, SLT, 4X4, 6.7L CTD with 36,000 miles. I am the original owner of the vehicle. I have just returned for our fall outing, pulling my 30' fifth wheel 4,300 miles....

A very common problem, I had the same happen on my 2007 6.7. At 18k turbo died (soot)...Now at 114k have had the EGR cooler cleaned and/or replaced 4 times now and at 107k another turbo ($5,100)...Seems that 2007.5 was a beta emissions system...Run with the exhaust brake ON to help ensure that the Varible nozzel turbo stays free (of EGR produced soot) and operable...Investigate regular preventive turbo soot cleanings by technician. DPF cracked at about 44k covered by warranty...Causes were as follows:
Casual driving (i.e. short distance drives, stop & goes, no loads) will prevent passive regen of the DPF (a controlled burn in DPF per temporary computer enriched injectors - provides excess unburned fuel source for controlled regen burn)...Eventually (without regular regenerations), the DPF gets plugged, thus when the passive burn finally does begin (one fine day after about 40 min of steady engine operation), the heavily soot laden DPF overheats from whats now an extended burn & temp and cracks its housing, sending smelly exhaust fumes up through the cowl and into the cab...By this time the EGR circuit is also already well plugged with soot, and your likely getting light headed or headaches from the fumes as well...EGR cooler size was made larger in later years...

Root cause is excess soot via EGR valve through the exhaust tract...
