ECU Failure
I have to report that after four and a half weeks off the road, my Xtrail lives again.
Driving normally on a Monday four weeks ago, with no previous history of any warnings, the MIL came on and stayed on hard.
Rang my local Nissan dealer who advised that I should bring it in immediately which I did. After half an hour, drooped shoulders revealed that they could not even read the fault codes as no commns were possible on the CAN Bus.
Late on the Friday of the first week, they advised that a donor ECU from a new Xtrail suggested I did have a dead ECU. It took approx 10 working days for the new unit to arrive from Japan and then a week of software loading and adaptation to get it to work -associated commns with the Body Control Module (BCM) which controls security etc proved to be an issue. I understand there were extensive discussions with Nissan and remote login sessions to finally achieve correct adaptation.
No other explanation apart from one other known instance in Brisbane - not sure if on a diesel.
Upside 1:
Nissan Australia were gracious enough to organise a hire car as well as provide an additional one year's warranty.
Upside 2 : when the ECU failed I was able to drive the car normally although I did not exceed 80km/hr.

Re: ECU Failure
What I don't understand is the "a week of software loading and ADAPTATION TO GET IT TO WORK".
Surely your model Xtrail is not so out-of-date that they don't make the same version of ECU anymore ?

Re: ECU Failure
not sure Kev, but as an engineer I would suggest that if the software constellation for the various devices on the canbus is not exactly right, its not going to happen.
So perhaps a combination of swre levels, experience, and dare I say it Jinglish service procedure instructions.

Re: ECU Failure
Kev,
If Nissan Australia were not advised or prepared for this type of fault by the engineers in Japan, they wouldn't know how to load the new software and might not have the tools/equipment to do so. Usually they only get Consult III readers that can flash the ECU but not load new software or calibrate it any further and this I guess what happened in this case where they needed support from Japan.
The T30 xtrail also had its share of ECU failures, although pretty rare.
It would be interesting to see if this ECU failure only happens in the diesel T31 or others as well.

Re: ECU Failure
OK Jalal, so worst case is that Nissan Australia have to wait a week or so to get a device shipped out from Japan to do the ECU reprogram, or send a pre-programmed ECU out for a T31 TL dci.
Seriously guys, for a TL dci T31 sold in Australia there would be a definitive list of standard equipment which it both controls and communicates with and the ECU should have already have the program in it. Otherwise, there should be a standard ECU program which Nissan Australia should be able to get from Japan to load into the ECU.
I doubt VERY MUCH that Nissan Japan would "fiddle" the ECU program on the assembly line for every ECU to get it to work nor expect local dealers to have the knowledge to be able to "fiddle" the ECU program when replacing one.

Re: ECU Failure
You're forgetting one important thing Kev and that is the main reason why the Nissan ECU program has not been cracked as yet by anyone in the world, as it is a well protected secret which the Japanese wouldn't even trust their own Nissan dealers in Australia to have or have access to

I think they did in your case. 
There must be a signal spiking the ECU for it to happen again.
Hope it gets sorted for you and costs you nothing.
