Mazda 6 diesel dpf
Discussion
Hi all, very new to this forum, great all the same, I have an issue with a bit of luck someone can help me with. Here goes, my Mazda 6 2.0 diesel sport, has the dreaded flashing dpf light on.car drives and pulls as normal, not in limp mode as others have had.I have read that this also acts as a service light? Is this really true? Really concerned as to drive now in case the motor goes bang! Reluctant to take to the "stealers" to get stroked of several £££££££ s or is the the start of big money worries as only had car approx 9 months, had intended to keep this one for a while, but getting nervous as hearing horror stories when googled! So any advice would be greatly appreciated, thanks....

buy one from motor factors, there about £350, plus the fluid which is about £30 IIRC, get local garage to fit, job done!The fluid is more important than the DPF, without it being injected into the exhaust the new filter will block up in no time.
It needs an oil change and the oil service reset, check the oil level isn't high as they tend to have the oil level rise due to failed regens, there's an upper mark on dipstick.
My sister in law has same car and i've had to do the same thing a few times.
If the light is on constant that's usually dpf fault

They don't use fluid.The fluid is more important than the DPF, without it being injected into the exhaust the new filter will block up in no time.
Is it a first gen Mazda6 (02-08) or second gen (08>) as one does put he DPF light on when a service is overdue, the other doesn't. When was it sat serviced (time/mileage)
There a re only really 2 or 3 things that go wrong to cause DPF issues on these, despite what you might find on the net, a they're definitely not the ticking time bombs that Life Saab Itch will have you believe.

Thanks for all who responded to my delema, was told car had full service at 79 k by previous owner, drove car today an s when turn car in corner the oil light flashes the disappears, oil level in car at minimum. Is the dpf light on the later models act as service indicator? Thinking to have car serviced to try rectify.
I wondered what he meant

Get the DPF deleted/remap if it's possible to do it on your car.
^^This if you canWhen I had this problem on a Mazda 5, it needed an oil service and then an oil reset rather than a full regeneration.
Another point worth mentioning is that Wurth now do this DPF cleaner - http://www.wurth.co.uk/product/dpfcleaner - which you pour into the DPF and then perform a regen either via a diagnostic tool or manually, used it a couple of times myself and used a fair bit by other friends in the trade and all have had success using it.

I would suggest putting some more oil in. The oil light flashing means that the oil pressure is very low.

Have the sump removed check the oil strainer for blockage, and get it cleaned out.
It should look like this
It could well look like this
The resulting oil starvation trashed the engine on this 2004 Mazda 6 Diesel

Have seen more than one like that, its a common problem caused by injectors fitting in the head, leaking blow-by gas into the engine.
Later cars also use the DPF light as a service reminder, the light flashes when a service/oil change is due, or if there is a fault with the injection system, a DTC code from the PCM will confirm whats needed. As far as I am aware not many non dealer diag machines can reset the oil counter, we reset loads after cars are serviced outside the dealer network.
