Thanks Matt. It definitely the DPF itself. Removed the pipe that bolts onto the dpf underneath the car. Started her up and voila. She now actually idles and revs and the horrendous noise has gone. So either dpf is completely blocked hence why no exhaust gas could get through the rear exhaust system or the internals in the dpf has collapsed. I now need to buy a new DPF I assume?
