Did the mechanic run a restriction test ( using Cummins insight) on the DPF filter after it was cleaned? This should be done. If it fails then replace the DPF filter. Freightliner in Baltimore has re-manned filters. I just had the same situation on my 2350. short of me buying a new turbo I was able to fix it myself. It turned out to be a bad filter even though it was cleaned. I did read that if you have a 2250, and it fails a restriction test, then the filter must be replaced. The reedman filter that I bought from Freightliner in Baltimore was $900 - turning in the core. Another thought could be that the DPF differential sensor has gone bad also
