3. Locate the fuse box located under the bonnet and next to the battery. Pull out the 3 fuses: ENG CONT1 (15A), ENG CONT2 (10A), ENG CONT3 (20A). Refer to the pics below. Keep the fuses out for at least 5 minutes. This will cut all power to the ECU.
I am trying to reset the ECU, since i am facing some problems after a manifold and catalyst replacement, and i am not sure if this because of faulse tuning...
I tried to find the fuses described in the first post...but it seems like my Xtrails, are different..I went throught the topic but didn't find anything more.
Nor the description, neither the photo maches with my case....
I took a picture of mine, and it's like these...Any ideas?

Thanks in advance!

Re:
Are you looking at the right fuse box, to my knowledge there are more than one.
If it is the right one, just have a look at the lid and pull the corresponding fuses.

I read in the post, that this is the one, near the battery. The other one in the left, has only that big size fuses...so i believe it's the correct in the picture. I'll get a picture tomorrow, with the fuse box cover, that describes them....
I dont see anywhere these "ENG CONT1, ENG CONT2, ENG CONT3"

Re:
Dimitris,
This DIY Guide is written for the 2.5LT T30 models, yours is a 2.0LT model which we don't have in Australia, so the fuses layout will be different in yours.
I can't see anything from the photo you posted, it is too small. Also, please post a photo of the fise box cover.

Re:
Yep, disconnect the battery overnight and that would re-set the ECU in your case. I am not sure how to do a quick re-set for your 2.0LT T30 exy, as none of the fuses correspond with the ones specifc to the ECU power.
P.S. Please consider using PhotoBucket to host your photos and share them on the forum. It's much easier to use than the host you are using and doesn't have so many adverts and links to "underpants"

Just a thought...! Instead of disconnecting the battey, if i remove all of the small fuses in the picture (in case i am lucky and some of these are connected with the procedure above) will there be a possibility to harm anything??? 
Should i try (in my own risk of course) to see??
Can i understand, if i succeeded a reset (a sign other than the rpms lets say???)

Re:
I doubt it will work, the ECU fuses in your case are located somewhere else, so have a look arund the engine bay and see if you can find another fuse box and also have a look at the fuses under the steering wheel.

Re: Re:
I disconnected the battery.... 12 hours would be ok?
By the way...I was knocking my head in the wall, how on earth i could lock the back door,without the central locking working.....and i had to connect the battery again, lock, and then disconnect back to succeed .. LOLLLL
So...maybe it's very silly question...but is there a way to lock the back (5th) door without electric power????
For the history, the other fuse boxes are
1. Engine Area http://i39.tinypic.com/15d8y9.jpg
2. Under the wheel http://i39.tinypic.com/1z2zr6q.jpg

Re:
That 15A ENG CONT in the engine bay fuse box is the one you need. 12 hours should be enough.
I need to see the cover of the fuse box under the steering wheel. Looking at fuses tells me nothing
