I'd like to ad just a few more details about Gregozedobe DPF regenerating process.
The ECU runs extra fuel to burn the soot, but it is actually exhaust gas containg unburned diesel fuel from very rich mixture, that burns of the soot in DPF. By using DPF on engine to protect environment the engine's life is shortened by regenerating process, since the extra fuel washes of the oil film from cylinder walls and there is also more wear (pistons, turbocharger etc.) from extra heat from combustion process.
