Well the black soot may be indicative of some interference of the emissions systems by a dodgy garage or previous owner. A DPF should catch all the black soot / particulate matter, so none should be coming out the back.

I would look for some evidence of tampering to make sure somebody has not gutted / removed the DPF in which case you will have been landed with a lemon. If you bought it from a garage - take it back straight away before you start doing anything to it.
