What sort of speed and for how long do I need to be driving for the DPF on my diesel to be working?

You need to be running at a minimum 2000rpm, so you should always try to keep the engine close to this speed after starting up to help to reduce soot in the first place and help promote passive regeneration. The DPF will regenerate actively, using post injected diesel to burn off soot inside it whenever its sensors tell the system it needs to.
