Re: Particulate filter error resulting in MIL light
Dronus - do you know if the regen cycles are logged ?
I also have an inkling that with the 'cleaner' diesel, long run (high mileage) vehicles, the 10k interval can be stretched - I have in 28,000kms only had the 1k(at 2k), 10k(at 13k) and 20k(at 27k) - more because I have been busy - but I do check the oil colour on the dipstick and it has been very clean for a diesel.

Re: Particulate filter error resulting in MIL light
Hi all,
We have just completed 10,000km service. There were no errors recorded. This means that only when the MIL light appears does the ECM log an error.
Further to this they are unable to determine how many regeneration cycles have occurred.
Given that our DPF light had come on several times this meant that what we did following its occurrance ie drive over 70 kph for approx 10 minutes cleared the DPF adequately,allowing us to cover another 300 kms of city work and as far as Nissan are concerned, does not present any problems.
Since using the Bp ultimate the DPF error has not occurred and Nissan passed on that feedback to head office.
During the service I asked for and did get a printout of the ECM status surrounding the DPF. On the printout was the Diff exh pressure(61hPa), Exh gas temp1(112'C), Exh Gas temp2(73'C).
These results were provided using consult3 software . This will give me a reference at the next service as to DPF status, that is until Dronus and I get our way with the real time LCD dash feedback. As an aside the service guy said that the service took a long time due to an extensive period of our car talking via the internet to head office service. My hunch is a software patch was loaded as there appears to have had a system reset.
(Trip meter radio presets).
Further to this following the service, the fuel consumption figure recently went suddenly high ,over 8.2 lpkm and within 10 kms (same driving). I figured it was getting ready for a regeneration (remember at this point no DPF light) and when I went over 70 kph for 10 mins it droped down to 7.1 again and remained there for the next week of driving.
When I reset the fuel consumption when I notice this (and it has only occurred once ) it showed very high values 10- 12 lpkm but after its 70 kph burst its rapidly dropped and has been fine for a lot of city driving again with the fuel consumption 7 lpkm again. (ie if reset never gets above 7.4 after 5kms)
I can only guess that there has been a slight modification to the regeneration process but i'm only guessing however I feel it's occurring at a lower speed. The Nissan service said they dont know of any undates etc but its all done via servicing and connecting computer (consult3 ),and car to head office. It looks to me that your local service guy is out of the picture concerning software issues with this motor. The uploaded information is probably giving Nissan all the info they need.
Given the discussion on DPF and oil I provided my own Castrol SLX Professional OE SAE 5w-30 API SM/CF ACEA A3/B3/B4/C3 Part no 119563 ($9.60 pl), 20 litres and they changed the oil filter etc etc. total service cost inc GST $202
I choose not to use the Genuine Nissan firstly cause it was bloody expensive ($16.50 per litre ) and they did not know what it was but said it was suitable for our car.
Our provided oil appears to be quite specific for vehicles fitted with DPF devices, and they were happy to use it, verifying the customer supplied oil on the service sheet
Edit Spelling/ grammar/ clarification... I should re read before posting ... Mark
