Mazda CX-3 1.5d SE Nav - DPF. Bought a new CX-3 1.5d SE Nav at the end of April 2016. Great car & spec etc..but the flashing DPF light keeps coming on. It happened the first time with less than 500 miles on the clock & continues to be a BIG problem. It happens on a long run on motorway journeys. Just found this post and need some advice regarding a similar issue. My oil light came on in my 2014 2.2d and oil and filter change was done.

If this occurs, the engine can be force-started. Press and hold the push button start until the engine starts. Other procedures necessary for starting the engine such as having the key in the cabin, and depressing the clutch pedal (manual transaxle) or the brake pedal (automatic transaxle) are required. Notice the light under the DPF light looks like a squiggly ‘W’. Wait for all the lights to go off as normal then you are left with the regular lights and a flashing DPF light. Wait about 5 seconds and then pump the accelerator 10 times. Now that squiggly ‘W’ comes on then goes off. 2009 mazda 6: saloon has starting showing flashing dpf light on dash hi there, 2009 mazda 6 saloon has starting showing flashing dpf light on dash.
