Mazda 3 2.2D 141 Skyactive

raspberrypi67

Folks,

Just wondering if anyone is still on this thread and if they have the above mentioned engine?
My engine in th elast 6 months has a strage feeling around the 1600rpm as if the timing is slightly off. I notice it more in the lower gears ok.
What could cause this would anyone know.
I did mention it while I went for a service but they said it 'was fine' no error messages.
Once there was a loss of acceleration and a puff of blue smoke while I asselerated in the fast lane! Hasent happeded since.

PS whats this 'burn off' it has to do, I'm a newbie to this?

Cheers

DPF is a Diesel particulate Filter, which traps soot. Then running the engine reasonably hard burns it off.

If you drive (as someone upthread said) like a granny, the particulates are not burnt off. Mazda's rather strange system can then end up allowing diesel into the engine oil (so the level rises) and if not changed, the oil can self-combust and destroy the engine.

This was a problem on the Mazda 2.0 diesel, i do not know if the 2.2 has been showing the same issues.

I drove a Mazda 3 2.2 diesel for about 3 months earlier this year. Apart from the great torque, the engine itself felt very lumpy at times. I did quite a bit of mileage in it and made sure it was driven hard enough on the motorway daily. I used to notice that at low revs, it was pretty rough. It would have the tendency to produce short bursts of power, even if I had the throttle pedal set at a consistent angle. Very hard to describe, it was almost like there was an issue with the throttle pedal, however the dealer said nothing came back on the diagnostics.

The 2.2d Mazda engine needs to have oil changes completed as per the schedule or it can be problematic. Possible that the previous owner/driver hadn't kept this up, however I never checked as it was a loan car.

When you say the timing feels off, is it just idling rough?

At least in the old 2.0, "can be problematic" meant "may turn into a large paperweight". Complete replacement needed - and the same thing would happen again, this was not due to any faulty parts, just the driver's driving style and not changing the oil often enough.

Hi,

Thanks for that info, yes its like you described 100%. At low revs around the 16-1800rpm is rough ok.
I changed the oil myself only about 7 months ago, wonder if its worth doing again before the winter....?
funny, I remember going to the motor factors in Celbridge looking for 0W 30 oil, he laughed saying that ' that was the equivalent to water' doesent exist and really they mean 5w 30. This I assume WOULD do would it?

Anyway, getting back to my original Q, I also went to the dealer said the diags showed nothing...I'd say they dident even test drive the car, noone in garages really give a Sh1t, do they? Wont go there now...

Does anyone else do their own servicing?

Cheers

PS, whats the best way to run the particles out and cleaning....120 km in 5th??

The dpf will burn off every 200-230km. Doesn't matter if you're doing motorway or not. You just have to make sure you don't turn the car off when it is regenerating. On the centre display in the fuel monitor. The engine symbol that is usually blue in colour will turn grey when dpf is burning off. Once it turns blue again it's finished. I reset the distance trip and forget till 200km. I turn fuel monitor back on then. My dpf has started to burn off even after 2-300 yards down the road after sitting all day/night.

Oh indeed, the PSA unit. Sounded like a bag of spanners too. An awful design on those.

No, the motor with the DPF problem was an all-Mazda effort.

I've never noticed my Mazda doing any burn out....still very gripy at the 1500rpm mark most days still...wonder if I write to mazda what they'll say...
