    Have you tried to do a dpf regen? Is the car running OK or in limp mode?

        I've just googled the fault code and it's showing as the dpf pressure sensor so a forced regen won't work and it'll probably need a new sensor

            I've not changed one on mine but it shouldn't be too hard a job to change

                Apparently, the pressure sensor pipe on the Insignia is located at the top right hand corner of the engine, the sensor pipe comes out of the top of the dpf and then around the end of the cylinder head to the sensor thats located at the back of the engine bolted to the inlet manifold. The dpf is bolted onto the turbo and is squashed between engine and radiator
