A hint was in my second, T30, thread.
I allways looked at the T31 diesel auto adverts and one that had come down a bit from its prize. So i brought it home.

It is a 2012 LE grade, 2.0 diesel with the auto box.
Front and rear heated leather seats,
rear camera in the mirror.
Xenon head lights,
Auto whipers. auto headlights an so on.

Here is a bit scratced spots.

Nice - anything planned for it?

Cheers

Nice ahto, we wait for the mods

First on the line is tow bar.
Then the speakers- on the T30 are better. Not much, but better.
Fit a aux transmission cooler,
improve sound proofing, The doors have nothing in them.
maybe a remap, with egr disable.
The only problem is that the mic for BT does not work, also the mic with the Pioneer. Maybe that is because i use Nokia Lumia with WP 8.1. Have to try with wife's android.
Rear camera image is on the mirror, but not on the head unit.
I try to find a Left side luggage drawer for decent price, but i think it is Mission Impossible.

Hi Ahto

Thats a nice looking motor. As already said, Im looking forward to see what mod's you do over the coming months.

Kind Regards
Mike

Oh and get the PTC heater to work. Mine does not work also. Went to the dealer to check with the Consult 3. The technican sayd that there is no PTC heater in the BCM section. In the fusebox are fuses and reays.
They sayd to book another 1-2 hours, so they can fiddle withe the BCM.
When there is no other option that replace and reprogramm the BCM, then i will connect the signal from the heated seats to the PTC relays.

Is that all?! Looking forward to hearing how you get on.

I followed with envy your work on your T30, so I'm glad you've got a T31 so I can learn how you do it!

Cheers

The PTC heater relays are ground side controlled(on the x-trail). That means that the climare control panel(auto amp in nissan terms) sends ground to the relays, when outside temp is below 5c and coolant temp is under 70c(according to Kia cee'd service manual).
My thought is that, the hardware is there, the Repair and testing in service manaul is there, I think that Nissan had stepped off on half the way, because no warm air is coming from vents after a minute. ECM, BCM or the auto amp has no algoritm for that.

With help from google translate i studied the Russian QQ owners club forum. And one of them fitted the heater element from 1.5dci to a 2.0 petrol. Because below -25c, defosting is hard even to petrol engines.
He used a 50A relay and fuse and took trigering +12v from ac panel IGN wire.
I have all the hardware in place, but mine is the facelift model and no service manual for it yer from the net, the wiring colors are a bit different from the 2007-2010 model. I have to find the wires from the AC panel to the relays manally.
My plan is to take relay, and make it supply groud via a switch to the PTC relays. Had to test the alternator for its power, can it handle the full power in idle or have to use 1/3 or 2/3.

What do you guys think? is it worth to pay the dealer, to try to get it work like it sould? They can not quarantee to get it work. Or do the manual override?

Would it be nice that it should work like this:
