you have an air leak, either your plenum pipes (there are 4) or an inlet manifold. Get a HIGH pressure test done asap.

It's not the DPF that is root cause so cleaning it won't fix it.

If your car wont regen then stg is inhibiting the process. could be a number of things. Temps not high enough to complete. speed not in range. Less than 1/4 tank of fuel. etc et.
