My check engine light was on a week or so ago and the codes were related to the EGR. I took it to ford and they said there was a TSB for that so they flashed the computer and the problem was fixed. I noticed that since it was flashed a week or week and a half ago my truck has not gone into Regen. Usually every few days it would regen for 15 mis or so. I did see the "cleaning exhaust filter" message flash once but it turned right back off. I called my service adviser and he was clueless. He said if it doesn't regen by the next oil change he would look into it. Any ideas?
