Hi, sorry for posting a new topic as I am sure there is a topic somewhere within this site - just new to the site at the moment.
I purchased a 68 plate CX-5 2.2 150bhp manual on 1.9.2018. having done only 4600 miles, I needed an oil change much to my disappointment due to diesel contamination. My regular journey to and from work comprises of 50/60 mph driving up A roads and I do two 100 mile motorway journeys per month.
The problem for me was not not knowing when the regen was happening and how often it happens. I have read various comments on the internet suggesting 250/300 miles - can anyone confirm please?
Friday gone, I noticed for the first time my car conducting a regen, however, I had to stop at red lights. Indications were that it was still doing the regen and this continued for an additional 2 minutes once the lights went green. I'm hopeful all went well - just can't be sure.
I have also got a theory which I would like to put out their. On the IStop monitor, three conditions have to be met for the IStop function to work (Engine, Air Con, Battery). My understanding if one or all of these are not met then the IStop function will not work. Also, my understanding is that when the car is doing a regen, the IStop will not work. Based on this, can I monitor when the car is conducting a regen based on the blue glow for the engine going out along with an increased MPG.
I only ask, as I have not noticed any of the other indications such as loud fans or white smoke etc.
Many thanks for your time and hoping to hear some positive feedback. Negative also welcome of it comes with a positive spin on it.

I thought all this dilution was all sorted now on the later cars like yours. I have an old 13 reg cx5 and get very little dilution but I always try to finish a regen and will often drive further than needed just to finish the regen. Regens on my car seem to be around 280-400 miles. Also I only use the car for long journeys so I am sure that helps. It is true that I stop doesn’t work when doing a regen but there are lots of other reasons why it doesn’t come on particularly at this time of the year so wouldn’t be a good way of spotting a regen. I find keeping an eye on av mpg the best way of being aware of regens..

Hi and thanks for the reply. In response to you saying you thought the problems were now sorted on the newer models. The garage I bought it from are a bit in agreement with that as they said it should not be happening and can't understand why - it did not help that I had to go to a different Mazda dealer to get the oil changed due to proximity etc. They said it looks like my car needs a software update but they are not sure when it will be released (this is a bit confusing to me because if the problems should not be happening, how do they know it needs a software update that does not exist yet). The confusing part is the garage which undertook the oil change said it was perfectly normal for this to happen at 4600 miles/4.5 months old. I disagree as I should not have to undergo 3 oil changes per year. Discussions have taken place between both garages and it now appears that I may experience this again in the next 4600 miles. It was then hinted that it may be my driving style.
My driving style consists of a mixture of 40/50/60 mph to and from work which is about 17 miles each way. I also do two one hundred motorway drivings over the weekends per
Month. Whilst I agree that I am not a heavy mileage driver, on purchasing the car, I was informed that the petrol version I wanted would not really be suitable and my driving behaviour is best suited to the version I now own. I feel the sales team say one thing whilst the tech team contradict. They all should be singing of the same sheet tbh.
I suppose all I can do is monitor the Regens and do regular oil checks. I was hoping the Regens would be of a regular intervals so I could at least predict it happening and ensure I could time it on a route on the motorway etc. As far as Regens go, I take it they are only passive?
Also, when my car was performing a regen and then I had to stop at a red light, would this cause a regen failure? Or would it have successful because when the lights turned green the mpg was very low and the blue engine glow was out for about 2 minutes. Just don't know if I must drive at a set speed and with high revs (2200) to complete regen or if this can happen if I am in a 30 zone etc.
Sorry for all the Q's, just trying to be proactive in preventing undue problems.

Yes you can monitor whether the car is doing a regen by the lack of glow around the engine icon. The glow also won't be there if the engine is cold tho.
FWIW My previous 64 plate and my current 17 plate do a regen every 170-200 miles. They last maybe 7 miles at motorway speeds. I try to keep the revs above 2k to help it along.
-
As far as Regens go, I take it they are only passive?
The regens in a cx5 are only active, ie they inject diesel into the exhaust stroke to heat up dpf to high temperature. A passive regen is a regen that is done by driving the car hard(full throttle on steep hill e.g) and getting the dpf hot enough to burn ff particulate matter. Not sure the cx5 does passive regens as active regens are done at set intervals.
-
Sorry, got the active, passive bit wrong way round but you have confirmed what I thought in that they are timed intervals as i did try to force a regen on motorway but no regen took place.
-
I can only manage 6500 mile between oil change warning illuminations - which is a bit disappointing when the service interval @12000 miles cannot be achieved. Fortunately for me I am only doing 7000 miles per year.
Strange though - I have never been aware of any regeneration taking place!

As your fully consumption is only 39mpg for a manual car I assume that you are mainly doing short traffic town centre type driving. During this type of driving it is harder to detect a regen using the av mpg method. When you are cruising on motorway the av mpg stays fairly constant, but drops a bit if speed goes up and goes up a bit when av speed is slower, when a regen starts that av figure drops noticeably when you were not expecting it to. During high traffic town centre type driving the figures go up and down a lot anyway depending on t/lights acceleration etc.so it’s harder to recognise a drop caused by regen.

On my June 2018 built CX5, bought mid October 2018, I've done approx 3,300 miles and the oil level hasn't budged. According to Fuelly my average mpg is 43.4mpg. My previous 2016 CX5 averaged 40.0mpg and the oil level did rise a couple of mm over the max mark it was well below the X mark with no warning lights with oil changes at the annual interval. I average 11,500 miles per year. Notorious, I suggest there is something wrong with your car.

Hi everyone and thanks for the feedback given. I have today just noticed the car doing another regen which is 200 miles since the last one. I have now got a base line to work with as I now anticipate another regen in 200 miles. Trip computer reset to enable easy monitoring.
@jonno21. You may well be correct as the garage initial thoughts was that this is not correct given the age of my car and did say I may require a software update when it comes out. However, I am now keeping a close eye on everything now. To be honest, as I have been unaware of when previous Regens have been taking place, I could have been turning the engine off mid-way but can't be sure. Also, based on my mileage and the car doing a regen @ 200 miles (only based on previous two admittedly), that equates to 5 Regens a month that may not have completed. I am keeping an open mind on it and hoping things will stay trouble free until service on Sept 19. I am also going to do weekly oil checks as a precaution. If the problems persist, then I would for sure say the car is at fault. If the issues stop between now and Sept19 then I will accept it may be down to my driving style and not (foolishly) knowing when previous Regens have occurred.
Once again, thank you for your feedback and input on personal experiences. I hoping to be in a position to post a positive update in the months to come that may offer some reassurances to new cx5 owners.

Jonno, is yours the Adblue version?
-
Hi Anchorman, I know the Q was not directed at me but I thought the adblue only came out on the models released 01.09.2018. I think this is why the diesel models only have the one exhaust whereas previous non adblue had the two exhausts.

Hi Anchorman - Yes, It's the Adblue version. Notorious - I have only one exhaust pipe.

Collected my GT today. Single exhaust and I shall be watching my oil carefully!

Hi Anchorman. Would you mind telling me where you ordered your Adblue from? I've seen it on sale at my local Texaco filling station and I think Halfords sell it as well? No valve might be an issue causing spillage etc which is not recommended, or am I making it more complicated than it needs to be? This Adblue business is all new to me.

Hi Just went to my local Aldi and they still had AdBlue on sale see link

Thanks Deano, I'll have a look tomorrow.
Update - they had run out.

I’ve never bought Adblue before despite being a mechanic for years. I decided to buy a branded product so I got Redex from Eurocarparts. It was subject to the weekly deal so it was £7.14 for 5 litres.

I should have mentioned. The smaller bottles are about £15 but they have the valve in the neck you need to use it. I’m hoping I can decant the 5 litres but I’ll let you know when it comes.

Thanks again. I don't know if this would do the job? What do you think? https://www.eurocarparts.com/ecp/p/car-accessories/engine-oils-and-car-fluids/car-additives/diesel-system-additives/?542770532&0&cc5_862

That looks better value as it definitely has the spout. The 5 litre one I’ve ordered has “a” spout but whether it will open the valve remains to be seen.

Hi
I have a 2014 model automatic and over the past 30k miles have learned pretty much how the regen works. I can confirm the istop doesn't work during an active regen so is a good indicator in the absence of a dashboard light (shame on you Mazda), I can also tell an active regen is happening when I hear the exhaust note 'burble' when slowing to a stop. When a regen is on, to avoid fuel dumping into the sump I try to keep revs at 3k (yes I know not always possible!) as in my experience lower revs don't ensure proper regen temperature. I do over 20k miles per year, about 80% on country roads and motorways with the remainder around town and the regen seems to kick in about every 200-300 miles, once or twice a tankful. The type of diesel seems to make little difference, and I aim to get around 39-41mpg on a clean DPF, although if cruising above 75 mph on the motorway it will drop off into the low-mid 30s. Another way to tell when a regen is happening is to reset the average mpg indicator every two tankfuls, and when you see it drop significantly (by 1-2 mpg) for no obvious reason (like going up a steep hill) then you know diesel is being siphoned off for a regen. By managing the regens this way I am achieving full service intervals between oil changes. My Mazda dealer still wont acknowledge the problem - they say the oil pressure warning light is a 'service interval indicator' ;D ;D ;D. By the way, I also tried a DPF cleaner additive and it worked well, with average mpg going up to about 43, but it only lasted through the subsequent non-dosed tankful before it went back to normal. At £15 per dose therefore its not worth it in my opinion.
Whilst the CX5 is a great car in all other respects, its a shame I have to 'manage' the engine. My next car will be electric ....

I'm not aware of any car manufacturer who fits a warning light to show that a regen is happening. My 2018 model CX5 averages 45mpg when monitoring via Fuelly.com and the regens are approx every 500 miles although there's no burbling sound and I can only tell when there's a sudden dip in mpg. The regen only seems to last about 5 minutes. So far at 5,000 miles the oil level on the dipstick hasn't budged from new. Incidentally, I can comfortably get to 400 miles on a tank before the low fuel warning light comes on. Looks like some improvements have been made since the 2014 model.

My previously owned 64 plate 175ps AWD auto initially did regens about every 250 miles. However, not too long after I bought it, it threw an oil pressure low light, was taken to Mazda for an oil & filter change and "an update". It then did regens every 180-200 miles. It did the 'burble' on the over-run as described by oldsteel above, and I tried to keep the revs above 2k while it finished its regen. They lasted about 6-7 miles on a motorway. It returned approx 40mpg, slightly better in summer (also as per oldsteel's experience) - all calculated by litres used per miles travelled. IIRC the computer always read about 10% high. It ran approx 400 miles before the low fuel light came on, and took about 45 litres to fill. I also achieved a full year (11.5k miles) between oil changes, and the oil level didn't rise.
My current 17 plate 150ps 2WD auto also does a regen every 180-200 miles. It also does the burble, and I also keep the revs up while it does its thing. They last the same 6-7 miles as the previous car. This one returns about 45mpg, although the computer drastically over-reads. If driven with a light foot for a whole tank the read-out can be as much as 57mpg, even tho it's only doing 45-47mpg. It covers about 450 miles per tank of 45 litres before the low fuel light. I've only had it 8 months (and covered about 7k miles) but so far the oil level hasn't risen, and I expect/hope to make it to it's scheduled service in 2 months without issue.
Jonno21 - I'm not familiar with Fuelly, but your miles covered per tank seem to exactly coincide with mine on my 64 plate. How many litres are you adding to fill it? I believe the tank sizes are the same 56 or 58 litres across the board.

I had a 2016 which got stolen. It did a regen every 110 miles or so, made the noise, istop cut out, smelled of hot metal, diluted the fuel - the full works. Then i had a 17, it didn’t make the noise or dilute the oil (it had modified pistons and rings) and as far as I could tell, did a regen about double the mileage of the 16. I’ve now got a 19 (adblue model) that might be diluting slightly due to entirely new style injectors and still does the odd regen (not sure how many miles yet) and also does “fast idle due to injector cleaning” which is something new.
They don’t give warning lights (like any other manufacturer) because 99.9% of drivers don’t want to know or alter their driving. There is no benefit in knowing and no benefit in altering driving style. The only downside of interrupting a regen by stopping the engine is that it will start another as soon as it gets to temperature so the process is drawn out - not a problem for most drivers. I certainly won’t pretend I’m doing any good by keeping the revs high or avoiding turning it off part way through. Stop worrying about it, it’s spoiling your experience with the car.

The only reason I got concerned about this was two separate 'red light' message events at a cost of £150 a pop at the dealer for an oil change, plus the inconvenience. Until then I was blissfully ignorant, but it prompted me to read up on the process in this forum and I now 'manage' it by increasing revs when I notice a regen, and so far its been successful in that I have reached two service intervals with no intervening red light. My theory is that if you drive the auto with a light right foot, the revs rarely go above 1500 around town, not creating enough heat for the regen to work - resulting in oil dilution. I confirm under normal circumstances regens are every 180-200 miles. I would expect Mazda to have improved the whole process with the later engines, so pleased to note that few if any report similar issues in 2017 or later models. But my next car will still be electric ....

Hi Oldsteel
Any particular makes/model of electric cars in mind? I may be thinking of electric next time but at the moment the limited range/lack of charging points/cost of vehicle is putting me off. Any model equivalent to the CX5 is way too expensive at the moment. Tesla? Audi? Ha Ha, look at the prices. I could afford a Renault Twizy (Joke of a car)
-
Hi peeps, sorry for jumping in. I'm still not actually sure when my 2014 cx5 is doing a regen! I drive trucks which tell you when it's actually doing a passive regen, or indeed needing to sit and do a regen at high revs. You get so long to carry this out, then it goes into limp mode. I find it hard to believe this kind of feature isn't on cars.

It’s intentional to stop you worrying about t it. Your truck requires action.

Hi peeps, sorry for jumping in. I'm still not actually sure when my 2014 cx5 is doing a regen!
To be honest, neither do I on my 2015 model. When new the smell was worse than what I imagine a skunk would emit when in defence mode but now I never notice it by smell or increased consumption although it obviously must be happening from time to time. I now drive the car as and when needs must either short or long journeys and try and forget about these sort of issues. That said, what I do find increasingly annoying is having to check the oil level more frequently than with any other vehicle I have ever owned to see if it's rising to anywhere approaching the 'X' mark which at the moment it is - again. Based on this, I have now booked the car in for an oil change (which I do twice a year as a matter of course due to this issue) as I have two long distance journeys coming up and I have no intention of waiting on the hard shoulder for Mazda rescue to turn up.
Despite the comfort factor along with other plus points that one can associate with the CX5 for me this is a car that I have very little confidence in and would never recommend or indeed myself buy another CX5 in the future. At least with my earlier VW there was an indication like you have experienced that things weren't right and given an opportunity to correct it before going into limp mode if ignored. With my CX5 there is absolutely nothing with the lack of dashboard indication being the worst and that's not even mentioning the introduction of the 'X' mark as an indication that the oil is now heavily diluted. Who ever heard of such a thing?

It is frustrating I agree but it is very common even on the German brands. It isn’t a Mazda thing it’s a Euro 6 diesel thing and as Mazda we’re one of the first to meet Euro 6, they’ve suffered with it a long time. Just for info, they’ve just about cured it on the post 17 models. Some do it a little bit but you can get a full year with it hardly moving on the stick.

Many Thanks for your replies folks, I'm learning something new all the time. Every day is a school day as they say ????

Agree. Now at 9,500 and the oil level has increased slightly but still not up to the max mark. My previous 2013 and 2016 CX5's would have been heading to the "X" mark. I think i can leave it it until the annual service or at 12,500 miles. Old habits die hard so I still check the oil level weekly. Incidentally, the oil dilution level is now reading 30%. Should probably just get there before I get a warning message. I used to have a Renault Laguna (2010) which had an oil dilution sensor and it would always flash "service" at approx 9,000 miles. The mileage between services was officially 20,000 miles ::) ::)

I think i can leave it it until the annual service or at 12,500 miles. Old habits die hard so I still check the oil level weekly. Incidentally, the oil dilution level is now reading 30%. Should probably just get there before I get a warning message. I used to have a Renault Laguna (2010) which had an oil dilution sensor and it would always flash "service" at approx 9,000 miles. The mileage between services was officially 20,000 miles ::) ::)
How do you mean the oil dilution is 30% Jonno?

It is frustrating I agree but it is very common even on the German brands. It isn’t a Mazda thing it’s a Euro 6 diesel thing and as Mazda we’re one of the first to meet Euro 6, they’ve suffered with it a long time.

Hi Anchorman
When you go into the maintenance app on the Connect screen I'm on variable servicing and you can scroll down to the oil condition line and it gives a percentage. It started at 100% when new so I presume 100% is good and the lower the percentage the "less good" the oil condition is. I'm presuming at 0% it's "change the oil immediately, go to jail immediately,do not pass go, do not collect £200 :)

I've made a complete mess of the quote system so starting again. ::)

Ah right, I have mine set to 12500 miles and don’t use that screen. I’d seen the % screen but read that as time not dilution/viscosity as it is variable, it can’t give you a mileage.

Hi Anchorman
From the manual page 6-13 in footnote 1 there appears to be some sort of oil quality monitor if the maintenance is set to flexible as it was when I collected the car. My car still knows how many miles there is until the next service so I presume there's two sets of information going on. In an ideal world you would think that the sensor information and the mileage information would coincide. Let's hope so. The Laguna I had was so out of sync it was laughable.

My CX5 has 7500 miles on it, mostly long distance on motorways. I've just checked the oil and it hasn't moved from new. I check it more frequently than I used tp on the other cars I have had as some folk seem to be having trouble with oil on here. The adblue is down to 70% and I intend to have it topped up at its first service.

You'll need to specifically ask for that, it's NOT covered in the standard service checklist.

Yes, I know. Just thought I would see what they would charge. I will ask beforehand. I know how much I can get Adblue for and roughly how much I will need. It's things like Adblue and washer bottle top ups that show what the dealer is like for aftersales service. Too easy to get ripped off.
-
You can do it yourself. Use the chart to determine how much and don’t overfill it.

Just booked the first service for my CX5. I asked about the Adblue and was told that it was part of the service and topping up was included in the price.

My 2013 car has a very low mileage but I can honestly say I have never even been aware of a regen.
My fuel consumption has never been great and as I now live in the IOM with lots of hills and no maximum speed limit it is acceptable.
The odd burst at well over 70 mph probably helps as it blows all the cobwebs away.
-
Likewise – I have been trying to see a regeneration take place since my last post earlier this year but to no avail……………however my fuel consumption has gone from 43 on a good run to 47 since I dragged my caravan over the Pyrenees and back again in June for the second time. Perhaps the engine is finally run in now @ 19000 miles!

The later models give very little indication that they are regenerating but rest assured they do it.

When new my late 2015 car smelt worse than a skunk on heat when a regen was being performed and there was no possible way not to miss it. However, after a few software updates over time, although I have no way of knowing if this has had an effect, or simply that the car has accumulated a few more kilometres over time, but I've not noticed a regen taking place for a very long time. Of course it must be happening as you rightly point out, Anchorman.
