Regens galore DPFs in other small diesels seem to last longer between regens. Feedback from Mr Fish in this forum, quoted Mazda engineering sources re the amount of diesel injected on the exhaust stroke to burn off the dpf - and the time between regens. If the computer drives a regen...

Hi - bought a diesel CX5 in July 2012. I had oil changes at 2800, 4000, 7800 and an early 10k service at 8700 so I could drive it 2k without worrying. Had a PCM reprogram at 11700klms. Now done 17370klms and the oil growth is OK. A long 3000 Klms trip saw no measurable oil growth. I am having...

As posted previously on this site, it is believed that there will be another software update. This is about the number of DPF regenerations. It may have something to do with the pressure differentials between the input and output pressures of the DPF. If this is the case then regens will be...

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...

I believe that at highway speeds my cx5 had more often regens in a recent 2800 k trip. However it could have been the lesser quality diesel in the countryside. Am still monitoring. The new dipstick has an x on it but it isn't as pronounced - however it is easily readable. According to the...

Hi Morsa. The reprogramming of the power control unit (pcu) is like upgrading the operating system on a computer. The firmware is reprogrammed by another computer connected to the pcu. Firmware is software which will not disappear like ROM. It probably uses an eeprom. That is an 'electrically...

I leave the istop on. Even when aircon is on (don't set to lowest temp) the green light of the istop is showing. The istop light goes out when the active regen occurs. Also the fuel use increases and when lifting off acc pedal fuel is not 00 but around 1.9. Also around town it sounds and...

Oil Growth Issue - Diesel GT CX5 Had my new dipstick and PCM reprogram on 14 Jan. Also the oil was changed at same time at no cost. At 11891ks on speedo drove from Canberra to Geelong, Adelaide and back to Canberra from last Sat to Thursday. Distance travelled, 2900ks and it was all on the...

Percentage dilution I am getting my oil tested after every service, by Caltest (Caltex). Had the oil changed at 2800, 4000, 7600 and early service at 8700 kilometres. My car is getting a new dipstick and PCM (ECU) next Monday. At the old X mark the diesel in the sump oil was circa 7%. So...

I have a clear plastic bonnet protecter on the edge of the bonnet (hood?). It is about 4 inches wide. Do you mean that? Also got clear plastic front light covers to match.

Hi people Mazda Aust contacted me by email yesterday. They wrote 'It involves a software update to the power control module and also a replacement oil dipstick.' Not sure about the 11 millimetres but the software update may alter the regen timings, diesel increase during the active regens...

Ah yes -Mazda Australia have said in Carsales Aust that it is fixed. If it isn't then it potentially is misrepresenting the case. I don't think Mazda Aust is that naive. So I look forward to a real fix!

I am getting my oil tested by Caltest (Caltex) every service so a dipstick fix alone shouldn't be the case. I think measuring the sump oil when hot (especially with diesel in it) is a problem for owners. Another issue is the rapidly rising oil. My oil tests will reveal more than the 350 mls...

Has to be more than the dipstick. My car had 350mls of diesel in the sump after 3600ks. Mazda Japan are aware of this and the rising oil problem.

I am an Australian owner of a CX5 high diesel, using low sulphur fuels with 10000k on the clock. It is 5 months old and has had 4 oil changes. I had the oil changed early so I could drive it 1240ks without it passing the x mark. Most of my trips are some distance and it fills to the x mark...

Dipsticks et al. Hi again. I think the dipstick fix is to prevent it touching the side of engine wall and giving a false reading. This may indeed address some people's concerns. The oil should be read about 10 minutes or more after the engine is stopped after a decent run. A Mazda Australia...

I put the active versus the passive regen question to Mazda Australia. They wrote back to me that Mazda Japan said passive regens do not occur. I had tested this on a drive to Gundagai and back on a 34c degree day and in 5th gear at 2500 revs. I noticed an active regen at 8200k and did the...

If Mazda Australia claims the oil rise is only associated with short trips then ipso facto, they admit the car is not fit for purpose. However im my case, my trips are not short as referred to by the senior Madza Australia executive. He doesn't sound like he has much of a technical grasp on...

Hi people. Official answer from Mazda Australia who contacted Mazda Japan. They wrote today saying that the 7% of diesel in the oil will not impact on the longevity of my engine and that a fix is immanent. I'll wait and see! Also Mazda said that the CX5 only uses active regenerations. I...
