You may have a problem with the dpf but it's unlikely to be the main problem. A blocked dpf is a sympton not a primary cause. Their are almost certainly other problems with incomplete combustion causing the soot such as over fueling injector, faulty O2 sensors, or possibly even the signs of excessively worn rings or fragmentation of the dpf or piston rings passing through to the exhaust.
If it was me I would be running a compression test and pulling the muffler to see what it is rattling.
