Mazda5 2010 - DPF light on after service - Railroad. 17 miles is hardly s long journey, and even assuming he did do that every day half of that mileage would be the engine warming up, during which time no DPF regeneration either passive or active would take place. Highway driving the whole way home sitting on 100 so no idea why automatic DPF regen never happened. Anyway, looking at purchasing and OBD tool to complete my own DPF regen at home as wanting to keep the car for along time. OBD tool im looking at is: Autel MS906BT. $3000NZD. Mazda 6 DPF Regeneration Procedure. A faulty DPF can be the cause of excessive smoke or a slow vehicle. If the dpf regenerates itself in a short period of time, then it can save fuel. However, if the regeneration takes more than 40 minutes, it may cause the engine to stall and cause a loss of power. If warnings are still ignored and soot loading continues to increase then the most likely outcome will be a new DPF costing around £1000. Mainly town based driving If your own car use is mainly town-based, stop/start driving it would be wise to choose petrol rather than risk the hassle of incomplete DPF regeneration. DPF additives A flashing orange DPF light (or whatever the primary activation mode is) just tells you that the filter is getting loaded up, and a burn or regeneration is necessary and/or overdue. The car knows this because it measures the pressure drop across the DPF. More pressure drop equals more clogging equals need to regenerate now. ― When the warning light turns on or flashes, repeat the procedure from Step 5 (start the engine). — 15 Verify that the learning value (O2S11_CAL) for the A/F sensor is other than 0. • If the learning value (02S11_CAL) for the A/F sensor is 0, repeat the procedure from Step 5 (start the engine). — 16 Clear the DTCs. After the engine has sufficiently warmed up (engine coolant temperature of 80 °C (176 °F) or more), depress the accelerator pedal and drive the vehicle at a speed of 20 km/h (12 mph) or more for about 15 to 20 minutes to eliminate the PM. When “DPF malfunction” is indicated. Contact an Authorized Mazda Dealer. I saw that on videos with ford static regeneration. But no smoke on mine, no fuss, nothing. Just hot. After the 50 min procedure, engine went back to idle, smooth. Job was done yesterday, and this morning i logged in to forscan android, for data logging. DPF_load at idle showed 1%, and after 15 minutes driving went up to 18% and stabilized. DPF Mazda 6 2.2 DieselYour Mazda's DPF is an important part of your vehicle's emissions control system. It filters harmful particles out of exhaust gas. When enough particles build up inside the DPF, the vehicle begins the regeneration process.
