Mazda 6 oil light on & P253F oil dilution, reset procedure

[@AndyMan-mr1hy]

Brilliant thanks buddy. It's been doing my head in. My wife's 2011 Mazda 6 started revving at 1500 but was in limp mode and dash warning lights on.
Oil level was ok after quick look and nothing else made sense..THEN she informed me that the oil was low the other day so neighbour (fellow Mazda owner) topped it up but neither of them told me.
So I recheck the oil and it was high.
So I drained off oil to correct level, I reset the oil system (on 2011 I had to just turn electric system on via ignition turn stage but not start engine. Then hold cluster illumination button down for 10 secs to clear oil data)
After that I disconnected battery for ten mins to reset light. Reconnected and boom. All back to normal.
Just nipping it off to garage now for code reading to check it's nothing else.
Thanks for video as it gave me an idea to check. I've subbed 👍😀

Well done Andy, theses Mazda’s can be sometimes a little tricky but it sounds like you got it sorted, well done mate 💪💪

Thanks Peter...Great informative video...have a 2014 Mazda 6 with the same issue...requires regular oil changes to keep off that warning light.

Sometimes people might not expect and oil light to be illuminated due to a reset. So hopefully it will help someone out 🤞

Not necessarily, but I do it everytime just to be safe & avoid any comebacks 😁😁

Nipped out & bought a Mk1 Freelander - for one reason & one reason only, the old-skool Perkins diesel engine it has. It "needs" 2 electrical feeds - fuel cut off & the starter motor.. plus it has an exhaust pipe - as in its just a pipe with a silencer. Had my eyes opened with the bills I see customers swallowing for "Modernity".. Lets not. :-) I bought 2 as it happens - I chucked one in a corner as "The Spares Department".

[@kennedysgarage3281]

Any one that knows or works on car does just that. Even Dave Sterling has a Toyota Hilux Surf for all his long journeys. Wise men stick with the older technology.
The very best of luck with it James, not that you’ll need it 🤞🤞🤞

[@padraigryan2588]

Exhaust boost pressure sensor was faulty hence no proper regens being done either which led to large soot deposits in dpf.

[@kennedysgarage3281]

Cars need everything to be right inorder to perform regenerations, but no one ever seems to realise this 🤷🏼‍♂️🤷🏼‍♂️

[@michaelmcist]

Same problem happened on my 131 reg mazda 6 .Engine was bollaxed, had to get a reconditioned one from a garage in Dublin, within a year same problem, low oil pressure warning again, thought that was all in the past with the new engine, how wrong was i. Found a mechanic in Catletownroche who services changes the oil every 6 months, he adds a thickener in with the oil, have not had a low oil pressure fault since. Do you know if Mazda fixed all these low oil pressure problems from 2017 onwards, the guys in garage in Dublin said they did.

[@kennedysgarage3281]

Was it a reconditioned or secondhand engine??
I find all secondhand engines can be quite close to suffering from all the generic failures that they suffer from 😬😬
Injector washers fail, causing carbon to build up under the rocker cover. Then that carbon blocks the oil strainer. This causes a loss in oil pressure thus big end & turbo failure 🤷🏼‍♂️

[@michaelmcist]

@kennedysgarage3281 they specialise in reconditioned engines, you have to give them your old engine, then yours is probably reconditioned for the next
Mazda 6 customer.

Is this reset system the same as the ford Mondeo dilution warning Peter. Have seen this on them.

Sorry Chris, but I don’t really understand the question. Is the reset process the as on a Mondeo ?? Is that it

[@the_retired_mechanic]

@@kennedysgarage3281 yes. I know ford do have the same diluted oil warning and I know from past experience they don't just allow you to reset service as a cure. Do ford use the same system as Mazda

[@kennedysgarage3281]

@@the_retired_mechanic I’m actually not sure Chris, I haven’t encountered it on a Ford yet. But as you said, just a service reset doesn’t reset the ‘oil dilution reset’
I just thought it would be interesting for someone that the engine oil light actually illuminates when it has counted down.
So it’s handy to know if I do come across it on a Ford 😉🙏🙏

[@lucaseaston]

Hey mate, great video.
I'm having the same issue with my Mazda 6 Diesel, resetting the Oil Dilution fault makes the error go away for a short time, but it comes back again because the ECU needs to have the Oil Data Reset (I can see with my scan tool that the oil dilution level has not changed since I changed the oil and reset the service on the dash) as the oil dilution level is not a sensor, it is a value that's stored in the ECU and calculated every time a DPF regeneration doesn't complete before the engine is shut down.
Is there a way to reset the oil data? Or do I have to pay Mazda the $185 they want to do it for me.

[@kennedysgarage3281]

The oil deterioration reset is the oil data reset. I’m assuming that you scantool most likely just doesn’t have the capabilities to do this 🤔🤔
What type of scantool are you using??

[@lucaseaston]

@@kennedysgarage3281 Foxwell scan tool. It has oil reset, but doesn’t seem to work on the Mazda 6. It says the manual reset is done by holding the TRIP button while switching the ignition on. But that just puts the dash into test mode.
I’ll see a friend, if his scan tool can do a proper oil data reset.

@@lucaseaston Autel would be best & just copy my video 😉🤞🤞

[@caileme]

I'd be almost willing to bet that if you pulled the rocker cover, the exhaust cam lobes are worn. Over the last 6 months I have been in communication with most of the independent diesel service garages in my country and this engine is "famous" for its cam shaft failures. Anything to do with excessive carbon signs, high oil, dpf issues etc is almost always related back to the exhaust cam lobes. Currently taking Mazda to court for a 2016 engine that the exhaust cam shaft lobes are gone with only 50k kms on the clock, and with oil changes every 7k kms since new!

[@kennedysgarage3281]

I’m changing camshafts at around 2 per week. And yes, it is a really common problem after around 120,000 kms. If exhaust gases cannot get out, fresh air cannot get in. This causes loads of problems 🤷🏼‍♂️🤷🏼‍♂️

[@krzysiekp9753]

For mazda is best to use forscan there are many service options which helps to read fault codes run dpf reg. etc.

[@Machine-rx6wf]

Concerned about my car . 66 plate cx5 with £79 k miles . Mechanic not getting to root of problem and costs mounting . Changed oil as level was high , saying diesel mixing with it. Cleaned turbo sensor, hes now saying intake manifold needs cleaned . Another mechanic says turbo . How far do you go , at what stage do you stop .
This is a car with full service history and now 3 oil changes in one year .
I've got a guy booked to do a carbon clean and he seems to know what issue is so I'm hoping this helps.
After watching your videos I'm thinking if I can get some sort of repair I should be thinking of selling car on seeing as there is so many problems associated with this engine .
I had an 11 plate takuya sport few years ago . Lovely car and never had any issue whatsoever with it . I thought Mazdas were bullet proof cars but I realise now with emmisions etc these modern cars are just money pits now with so many things to go wrong.

[@caileme]

@@Machine-rx6wf Before you spend any more money, get someone to lift the rocker cover and check the exhaust cams. If the cam shaft is ok, big sigh of relief. Now you can work backwards from the ignition chamber - check injectors, replace injector seals, check valve seats, clean intake / dpf etc. If the cam shaft is worn then that is a very very worrying and expensive problem (oil pump, strainer, oil chain, turbo, vacuum pump, bearings, sensors etc all can be impacted by the degradation of the exhaust cam lobe). There is a reason the engine is producing excess carbon, just cleaning the carbon out doesn't fix the problem......

[@caileme]

@@kennedysgarage3281 At 120k and requiring a cam shaft change, imho the cam shaft isn't fit for purpose and I wonder when someone is going to bring a class action against Mazda. Especially with the Technical Service Bulletin that Mazda put out back in 2014 / 15 specifically about cam shaft exhaust lobe wear / failure in these engines.

Lads....how pray tell can I know if my Mazda 6 2.2 is doing proper regens ?....I see comments about all the time but for the ordinary DIY car guy it's a hard one to determine.....probably strange question to ask but there is no indicator on the dash to tell you the car has just completed a successful regen.....can you tell from the way the car is driving or sounds ?

[@kennedysgarage3281]

Hi Paudraig, it is very hard to tell even for us. We look at exhaust temperatures on the scan tool to see when it is being done . Regeneration happens over 600degrees. We can also see the distance since last regeneration in live data. Dpf issues only happen due to underlying engine issues

[@sen5908]

Can I ask what year is your mazda please, because there is a way, without any scanners or nothing, as the car does tell you when it's doing a regen

[@padraigryan2588]

My Mazda 6 is a 2014 model with 167k kilometres on the clock.
I have noticed lately that oil dliuation level is rising faster than it normally did and hence I'm doing oil changes more often.Lovely car but the oil level issue is a big bone of contention with me 😢

Hi..yes my Mazda 6 does have the eloop recharge system...I can see it recharging on the drivers instrument panel over on the right-hand side. I see the levels go up and down depending on my driving/braking.The vast majority of my daily driving is motorway at 100+klms/hours so I would be surprised if it would be a dpf issue.....but it be an exhaust camshaft that needs replacing ??

[@damienkearns9922]

Great one as always Peter…at 230k odd km I suspect the exhaust cam shaft is just a straight bar 🫣 Have you ever tried using the borescope through the oil filler hole to see some of the lobes on the exhaust cam or is it even possible?
I Haven’t been working on a Mazda in a few months now so I’m starting to forget the geography…the shakes and twitches are starting to really get noticeable now 🤪😜

[@caileme]

You can't see the exhaust lobes with a boroscope because the injector line seals them off from the filler cap. The only way is to lift the rocker cover unless you wanted to drill holes into the rocker cover......

[@kennedysgarage3281]

Hi Damien & caileme, I’m changing camshafts on these very often. 1 or 2 a week, isn’t it great 😬. I use the milestone of, the camshaft is needed after 120,000 kms. Unless it has been replaced, which is unlikely 🤷🏼‍♂️
It is impossible to see it without rocker cover removal & at that stage it is easier keep going and replace it if needed.

Also when on scanner , scrolling live data will show 'exhaust pressure sensor' info. With a rev ( anything above 2000rpm ), if it exceeds the perimeters >150kpa , the exhaust pressure sensor is stuffed , and needs replacement.

[@Adam-7_7_7]

These Mazda's 😡.
Sooty engines , dpf problems , oil dilution problems.
Its funny that when people in South Africa import them, there is no requirement for a diesel to have a dpf or adblue setup. They simply cancel the dpf , trick the sensors with dummy sensors , and the result is better performance , better fuel economy and a engine that will last a hell of alot longer.
But in U.K , Canada , USA , Europe , NZ and here in OZ ,its required by law ( heavy fines if you mod )

[@kennedysgarage3281]

In Ireland quite a lot of dpf delete companies have stopped doing it. Simply due to cause & effect, there is always something inhibiting Dpf regenerations (intake manifold blocked or exhaust camshaft worn)
I find once they are fixed right, they are a mighty machine 🤷🏼‍♂️🤷🏼‍♂️
