I have a question:

in the australian forum I found several statments that regeneration
is also indicated by "I-Stop Indicator" off.

Tell-tale sign for this happening is the i-Stop light being off and a low-pitched hum in the car when you take your foot off the accelerator.

I recall having high fuel consumption and a bit of a burny smell the first (and only?) time DPF regeneration happened (I kinda surmised this to be the case after the fact) the i-Stop light was OFF (not amber) for the duration.
When fuel consumption returned to normal, i-Stop light was back on

The 'evidence' for me was:
1. burning smell
2. high fuel consumption
3. i-Stop light OFF (not amber)

Only for the Australian version of the car ? Germany: I-Stop green = I-Stop stopped the engine, I-Stop yellow = function switched off, I-Stop light off = function switched on

Is someone able to explain this item. Would be excellent to have 100% indication for testing purpose.

q50_treiber, we, poor european, have a downgraded versin of the CX-5 in some aspects.
One of this is the functionning of the i-stop light. We can't use it as a cue that the regens are in progress. The modes you describes is the same in all european cars.
In Aus or in Asia the green light is always on when the vehicle is running to indicate that the function is active that is the same as for our light off. So, if while running, their light (Aussi cars) goes off is because a regen is under way, or another problem which deactivates the function.

We must stop the car and try to force the i-stop to see if is active. Bad thing.

Thanks Morsa !

I read it already. This is similar to German experience with varies between 170 and 260 km.

In Aust my regens have occurred between 150 to 280 kms. It was driving across the desert at 110 on a 35c day that it had regens at 150 kms. Around Canberra in light traffic and higher speed roads than other cities the regens are around 250 kms. Being a semi-retired old guy with time I always ensure the the active regens complete.

For me the rising oil issue was because the car was delivered with a regen injection firmware mal- program. It went away with the PCU reprogram.

I think the car is brilliant but the way it was handled was clumsy. I found Mazda Australia would answer my questions honestly when emailed to them. The world has changed and Facebook, Forums et el. connects us all - so the old marketing ploy of denying issues doesn't work. It would be better if the issue was admitted not downplayed. However the proof of the pudding is what impact on sales the honesty or obfuscation strategies have.

Well it looks like the things are moving and actions are aproaching here too:

....sur des CX-5, on peut noter une augmentation anormale du niveau d'huile lie des rgn mal gres causant des consommations excessives. C'est un problme de jeunesse connu l'chelle mondiale (les premiers s'en tre aperus ont t les CC australiens). Rien de grave si c'est corrig.
Les reprogrammations sont en cours. La vidange est galement ralise afin d'liminer l'huile dtriore.
J'ai oubli de lui demander si un rappel tait ralis ou si les CC contactaient directement leurs clients.
Mais pour lui, il n'y a pas de mystre. C'est vrai et les corrections en cours.

Hi!
I got a CX5 AWD 2.2L Diesel 175PS Manual Gear Box!
After finishing the first 1500 km (70% Highway) the oil is rising up to 50% towards the X marking of the new dipstick!
That means, if i had the old dipstick the oil would have reached the X marking within 1500 km!!
What the fxxx is that???

 

[Morsa]

Chevyfredi, have you got the dipstick "B" with the car or they have changed it?. Have your car had the ECU reflash?, or it is brand new?.

 

[Chevyfredi]

Hi MORSA,
Car was first registered in February 2013(NEW).It came with the new dipstick Type"B"!
The X-Mark 25 mm above the"Full" point!
The present software status is not known to me.
I do have a date with a Mazda technician in March 2013!
I hope this helps.

 

[Morsa]

Thanks a lot. Chevy. We are making a survey with the cars who have "suffered" the software and dipstick upgrade, as well as to the new cars that, after VIN 150640, come wtih the stick "B". We don't know if these cars, like your are new software or not.

I have the new stick fitted on January , car registered June 2012, awaiting dealer call for the upgrade.

Vielen danke.

 

[Chevyfredi]

Hi MORSA
The VIN of my CX5 is higher than 150640!

 

[q50_treiber]

Hi Morsa,

Chevyfredi is also counted in the German statistic.
He is already the 3rd with a brandnew CX-5 rising oil up very fast. ( 850km, 1500km, 1700km).
This SW version seems to be worse and I am afraid I got it also by an update since end of jan.

Is someone aware if or when the Oil Rise SW fix is already programmed at factory ?
Somehow able to be detected ?

 

[Morsa]

Hi German fellows.

We have also some 3 colleagues with cars afer 150640 all with "B" stick, and we are watching them very closely, but we have not report of high rise oil on their cars to date. We don't know what soft they have. Some of the upgraded one are happy, as the australian change-man, to the moment. It may be that Mazda have only changed the dipstick on factory?

 

[eudrive33]

Hi all,

I would like to give you my theory on the case with "Chevyfredi".

The car as a read was received on February 1st of 2013 in Germany. Now let's do the math, shipping from Japan to Europe takes ~45days, additional logistics and transportation from/to factory/dealership 2 weeks. So the car left the factory around 1st of December 2012. At that time I'm pretty sure the new ECU software update was not released, but only the dipsticks 450B.
The only way we can be abosolutly sure is to find out the ECU software version. If anyone wants to point out how this can be done without visiting Mazda please let us know.

 

[Morsa]

eudrive33, I agree with your theory. In our spanish forum the guy whose car we use as reference for the first "B" stick from factory was delivered on Januray 23th. So more-less that Chevy (they may arrive in the same ship, differents stops). This man have no oil rise in, at least, 1500 Kms.

The new ECU was not avaible in December...so, those are only normal cases, impacted or not by the issue. Also I consider that the very much cool Germany may have an influence in the problem.

 

[q50_treiber]

Information needed:
4 weeks after my last PCM SW Update I was asked to get another one.
I complained a very rapid increase of oil after last update. ( I got already one extra oil change)

This new update is part of a new diagnosis update. I am afraid this is again not the sw update to solve oil rise.
My question is how the SW update against oil rise is done. By standard diagnosis or by a separat procedure with special equipement ( That's what I understood) ?
I have to go 120 km to my dealer and I don't want to do it for nothing.

I don't believe there is any special equipment required. PCM upgrades occur for all sorts of reasons and are applied using the standard servicing equipment. I waited at the dealership when mine was done in December and it took no more than 10 minutes.

 

[q50_treiber]

I understood this problem solving SW update is done by Mazda engineers and not by dealers with their standard service equipement.
So I am wrong ?
