Tony,I've had problems with DPF last year, went into limp mode and triggered engine light, then I reset it, drove some highway and it was good for a week or two, then again. So after few months of struggle I concluded it is a combination of possibly restricted DPF + chiptuning, so I removed DPF honeycomb and deleted DPF in ECU.It was OK for maybe half a year, then I begun noticing more and more hesitation when I gave it some gas at low rpm...it simply did not react quickly as before, and also begins smoking. But at higher rpms it pulled brutaly.So I am still suspicious about how DPF honeycomb was removed... on one side it was nice cut, while on another it was broke and teared. Maybe a piece or two went sideways and block exhaust flow, but as DPF is deleted in ECU, it does not trigger any code?I guess those sensors before and after DPF do not play any role now?
