My C320 CDi is the same model as yours on a 57 plate.
It does not have a DPF. If yours does, it will be stated on the datacard.
If it isn't, your car won't have a DPF.
I have looked at my data card, and can't see anything listed. One less thing to worry about then!
Edit: I think it is option code 474 if a dpf is fitted.
If you have a dpf fitted, I would have expected to see the dpf emblem warning light on the dash to illuminate briefly (along with all the other warning lights) during the light test procedure everytime you turn on the ignition..
