Re: Particulate filter error resulting in MIL light
When my x-trail went in for its 10,000km service, they used the castrol low ash oil, and when I queried the high price they told me that was the only oil available that you can use in this diesel engine.
At my 20,000km service, i asked about the oil again, and they said they now had available (as a spare part) the nissan genuine oil for this vehicle, and that it was cheaper than the castrol, and if i request it they can use this oil. So I did. I still have part of a 5 litre container left over in my garage to take in at the 30,000 service.
My point is, my vehicle has had no trouble using either the genuine Nissan or the castrol low ash oil, so changing from one oil to the other probably isn't going to make a difference. Unless, as pointed out above, somebody has put the WRONG oil in the motor.

 Re: Particulate filter error resulting in MIL light
Thanks for your replys.
The details of xtrail are 9800kms, on factory oil.
So unsure what the Japanese worker put in. What if Nissan Australia 'topped' it (them) up in the pre delivery ?
I think the fuel issue is probably the common thread here is SA. The BP ultimate is relatively recent and appears the only fuel EURO 5 compliant. It's the cetane level which is critical for the regen, ie must be greater than 51. Bp Ultimate has (off the top of my head ) 55.
VW are considering making it mandatory for all motors with PFDs to run on cetane 51 or above and 10ppm sulphur.
Could be ironic that all the PFD problems manifest themselves with city running with 'poor' quality fuel. That may explain why interstate users are not having as many issues as here. I was going past our local BP yesterday and noted Ultimate available! Went in it had been changed in the morning! How long does it take for the newer type to 'wash' through or has it been in the tanks for weeks? Monday I will speak with BP.
I'm going to get Nissan to liaise with me re 'blocked' PFD before allowing them to force a regen during the 10k's service.

Re: Particulate filter error resulting in MIL light
I have not seen BP Ultimate here in Adelaide anywhere.
I've recently started doing some extra highway runs during the day going to another worksite and everything seems to be behaving. I reakon that i can notice when the DPF is starting to get blocked as the engine seems sluggish compared to normal, after a bit of a run it spins freely again.
Im in two minds about the whole driving it harder to keep it clean, although i notice that my fuel economy is better if i don't labour the engine, which might result in less soot? Im not a mechanic so i can say that authoritatively.
I left a message with Nissan to get back to me in regards to the oil, and what they use in the X-Trails.
Interesting that the VW's are having a similar issue, it could very well be Aust fuel standards aren't up-to scratch. When i was at the dealer a while ago they mentioned that they had alot of problems with new Navara's in Sydney that tradies were using as they often carry heavy loads and never get above 60kmph; resulting in many returning to the dealer for manual regen.
Cheers,
dronus

Re: Particulate filter error resulting in MIL light
Hi Dronus, Hi Have what can only be the BEST NEWS FOR all Dci users (in SA).
Please look at the Bp web site select Diesel Ultimate and sites avaliable!!!! They have even got some northern areas now. Since the last tank full of the EURO 5 stuff no lights with same city crawling with the odd above 70 kph. I know it's early days but the motor sounds slighty different at idile???!!!. Fingers, legs etc crossed. Try a new tank full Dronus they have the fancy signs letting you know out the front but go to a sight say Glen Osmond where it has been available for a month to make sure its not a shandy of old and new. (I'm unsure about this status but will speak to Bp Monday) let me know what you think! Read the Adobe doc in the spec sheet. Now I have re read this it sounds like 'BS' but someone else might like to add whether fuel could have been the issue here all along!

Re: Particulate filter error resulting in MIL light
Well you South Aussies are lucky, it seems that BP Ultimate is NOT available in Victoria at all.
But since I haven't had any problems i'll keep using the normal old diesel at Safeway!

Re: Particulate filter error resulting in MIL light
Cool thanks I'll run this tank right down and give it a shot. I have a half tank left so that will give me time to find one that does volume.
I heard back from Lakeside Nissan this morning and they use Castrol SLX low ash oil when servicing diesel x-trails.

Re: Particulate filter error resulting in MIL light
I have just topped up with 53L of BP Ultimate Diesel from Angle Park ($1.15per litre).
Ill run it for a few weeks and then post back with any observations in relation to economy/consumption in the Fuels and Oils section under T31 Diesel Fuel Consumption Thread, and any DPF implications here in this thread.
I noticed that all of the pumps have been converted to Ultimate Diesel now at this servo. My normal servo doesnt have BP Ultimate Diesel yet.
I asked a friend of mine who follows the petroleum industries shenanagans in-depth and he suggests that the move to the cleaner burning and 55 - 60 cetane rating diesel is running behind schedule. The conspiracy theory is that Australia's Diesel is "Dirtier" than what is required to run the new Euro 5 rated turbo diesels, and the new generation of fuels will fix the problems we have been noticing.
Tempus est optimus iudex. (time is the best judge).

Re: Particulate filter error resulting in MIL light
So we may have rejected daylight saving but the West is for once in front, only because I think the stuff is refined at their refinery here in Kwinana.
I have been fortunate to run BP Ultimate Diesel from new (last August) and even in country WA. I did a 800km return trip to Geraldton yesterday and the motor pulled like a train overtaking the very long road trains on the Brand Highway. Would accelerate from 110 to 150 in fifth very very quickly and reassuringly.
Taking it in for a service (oil change) on Sat - I am stretching them to around 15k intervals given the long runs I do. Be interesting to see what Nissan says.
Hope you find it helps the running of your cars.
Just had it serviced this morning and asked them to let me know the number of times a regen has occurred if indeed this is logged by the ECU. Their comment was that no fault codes were noted (somewhat of a bland & expected answer) & that if the DPF light did come on, I should run the vehicle for at least 40mins.
So a question : do the regen events get logged?

Everything you said above is correct and exactly what I have been told today by Nissan when I mentioned the DPF regeneration problem.
They're getting a LOT of cases of incorrect engine oil being used with the T31 diesel and stressed on the fact that the Genuine Nissan (low ash) oil must be used just like the Navara D40 (which is also experiencing this DPF problem as a result of incorrect engine oil)
This dealer in particular is still doing the DPF re-generation warranty and it is not an easy task to do, but many other dealers have stopped doing this under warranty if the incorrect engine oil is detected.
One Navara D40 owner got charged $5000 to do the DPF re-generation process by one dealer because he had a diesel chip in his car and they said the performance chip caused this problem which the chip manufacturer totally refused, so all 3 of them (chip importer, Nissan dealer and the D40 owner) are now in court battling it out.
