Hi mate, hopefully NissanTechy will be able to answer this for you, but this is what i would try: Disconnect the battery for about 10 mins, then start the engine, let it tick over for about 5 mins, then switch off and do the ECU reset, and see how it goes. Then ignition on and press&hold both throttle and brake pedal until DPF light start flashing (takes a few tries until it works) Release both pedals and start the engine without touching any pedals.Let the regeneration complete (cca.20-30mins)after then shut off engine and write DPF off file. Thanks for the info. If the vehicle is continually driven as usual with the diesel particulate filter indicator light illuminated, PM increases and the indicator light may start flashing. If the diesel particulate filter indicator light starts flashing, have the vehicle inspected immediately at an expert repairer, we recommend an Authorised Mazda Repairer.
