What should I do if my DPF light comes on?
When the DPF light has become illuminated, it’s telling you that ‘passive regeneration’ has failed and that you need to actively regenerate the diesel particulate filter. You can do this by increasing your speed to more than 40mph for between 10 and 15 minutes.
Why is my Mazda 6’s DPF light flashing?
If you haven’t been travelling on motorways, or at higher speeds, for a period of time, your car can struggle to achieve the temperatures needed to burn away the particles, causing your DPF to become clogged. As it becomes clogged, an error message is sent to your ECU, which in turn causes the DPF light to flash, indicating a problem.
What should I do if my DPF light goes off?
The cheapest way is to service the car somewhere else and attend official Mazda dealership afterwards to reset the DPF light. Servicing the car per se, after the DPF flashing has gone off, will not eliminate flashing. They will charge you £85 for plugging your car to their machine.
Why does Mazda say the DPF fault is not a fault?

When does DPF reset on a Mazda 3?
The pic below shows what can happen when the engine oil gets polluted with diesel when repeated DPF regen cycles have occurred over a long period of time. It can also happen if you use the wrong engine oil. Check and clean it every 80 – 100 thousand kilometers.
How does a diesel particulate filter work on a Mazda?
Your Diesel Particulate Filter, or DPF, filters all the harmful particles from your exhaust gases, stopping them from escaping into the atmosphere. Over time these particles build up inside the filter. When they’ve built up to a certain level, your Mazda will start what’s called the ‘regeneration process’.
Why does my DPF light keep coming back on?
If the light returns or stays on after running this fix, then you DO have an issue with the DPF, Or a Stretched Timing Chain, or, there’s an issue with your oil such as it being overfilled past the X marker. Either way, if the light returns, immediately take it to your service centre. If the light stays out, it was just the “service due” light.
