Mazda 6 flashing DPF light

Vicxas

Hey lads,

Quick question for yiz.

Ive a 2.2 Mazda 6 129bhp

I was driving home this evening and the dpf light came on and continued to flash all the way home.

Now I've read online that this usually means its due a service (which is about right as shes at 64k) but is this true?

Any one else have experience with this?

George Dalton

Yes that is true.

Go get it check out ASAP by a proper mechanic. I lost an engine in my car due to it. It was a 2.2d 163bhp 09. Google DPF and Mazda engine failures and you will find some stories. Make sure you use the proper oil too

If George Dalton says it's true then you can bet your house on it

Vicxas

Cheers lads. Ive been reading conflicting reports on it.

Problem is i need the car for work this week and wont be off till Monday. Would she be safe to drive for another 300km?

Check your oil level before you go anywhere. The DPF light also flashes when it's been diluted with diesel and the level rises.

Checked this morning. Seems to be sitting just above full. But with all the residue im not sure.

Mine looks the same. What kind of driving do you do? If its mainly driving with engine revs below 2000rpm you need to give the car a good spin for 15 to 20 mins with revs around 2500rev (do not go below 2000revs). There will be a slight smell of burning from the dpf as it burns off. You will notice the mpg will be lower than normal. Make sure engine temp is in the middle of the gauge before you go to the 2500 for the burn off. You need to get onto a motorway or good road put car in 3rd or 4th gear and go to 2500 revs.

I normally take national roads and once or twice on the motorway, but the car is normally always under 2k revs come to think of it.

Ill sit on the motorway this afternoon and keep it over 2.5k

It gives the warning when the oil is over the full mark. The picture there shows the dipstick dirty, park it up and clean the residue off and dip it again and see the level.

When the oil level is high it could damage the engine. The by the book solution is an oil change. The oil isn't doing its job if diluted with diesel which could cause premature engine wear.

George Dalton

What we find with these is that nearly every time we service one there are fault codes logged relating to DPF regeneration not being completed so we end up having to do a forced regen. This generally keeps them going until the next service. They are an absolute disaster of an engine IMO. Which is a pity because the car itself is decent.

aido76

I also read that the service indicator needs to be reset properly or the system won't know if a service has been completed. The main issue with these cars is that the regeneration is not being completed as the cars are not driven in the right conditions to get the regeneration completed. This is the same issue with all diesel engines with dpf's. Problem with the mazda is the the excess diesel is dumped in to the oil so it is very important to check the oil level regularly. If oil level is halfway between full and the X get the oil changed asap.

There were lots of boardsies suggesting that the 2.2 solved these problems and it was safe to buy a 6 diesel again, but it seems that is not the case.

Squeaksoutloud

Are these issues carried on to the new model 6? Would love to pick one up next year if issues are sorted.

The hood cover says to change the oil when the level reaches the X. I won't be leaving it that long though. Gonna try and replace the oil and filters myself tomorrow

Replacing the oil and filter without resetting the oil data in the engine ECU is pointless IMO.

This statement just proves how ridiculus modern car with internal combustion technology has become.
I am happy to avoid all this hassle for as long as I can.

There's a mechanic in Dublin 9 that resets oil service intervals and does a full ecu diagnostic scan for only 15 euro. I've used him a few times, knowledgeable guy!

Vicxas

So i drove the car from Navan to dublin staying above 2.5k RPM and the light has stayed on.

So shes been booked in for a full service monday morning, i hope she can last until then without issue.

Vicxas

Right so I got the car back from the mechanics, and i've been told that a sensor in my exhaust failed and caused the DPF regen to not kick in.

So, does anyone know a good place to get a clean in the Navan area?

Boskowski

You measure the oil level when the car is warm after a drive but has been sitting for a short while, maybe ten minutes or so. Then you wipe the dipstick clean and stick it in there and pull it out. Not enough oil is bad, but too much oil is not good either. Its supposed to be between min and max, ideally right in the centre. Not rocket science really.

Bumping this thread rather than starting a new one as I’ve the same issue.

I only use the car for commuting to/from work so between rush hour traffic, red lights, roundabouts and dual carriageway driving it’s rare that I’m driving at 2500+ revs.

So question is do I need to continuously drive at 2500 revs for 20 mins and not dip below (like the Speed movies!) for the regen to kick in or would 4 or 5 days of worth of driving that way for 10 odd minutes a day do the trick? I tried it on the way home today and got about 8 mins at 2500 revs (100kmh 4th gear) before traffic forced me to slow, not sure if this was enough to cause any burn off, light still flashing.

If it has to be continuous driving at that rate then I’ll have to take the car out late at night because there isn’t a hope of getting 20+ mins on the work commute before something/someone forces me to slow and dip under 2000 revs.

Just for a heads up this is the 3rd time I’ve had the light flashing, previous 2 times I brought it to the mechanic who cleaned the DPF for €80 which buys me around a year and a half before it will come on again, hoping to sort myself this time round for the cost of a few extra quid burning diesel at high revs!

Cheers.
