Climate Correction:
1. The car is not running.
2. Set the air fan knob (left knob) to OFF
3. Insert the ignition key into the lock and turn to the ON position.
4. Not later than 10 seconds after turning the key to the ON position, press the recirculation button (on the middle knob) and hold for at least 5 seconds.
First, 2 recirculation lights will flash (most likely, the automatic recirculation mode will turn on, described in the operating instructions on page 4-13). Then those lights will go out. And the default adjustment will be set to 0°C. (A/C-OFF, FRE-OFF, REC-OFF)
5. By pressing the recirculation button once (on the middle knob), 3 lights will turn on and off: A / C and recirculation (FRE and REC) according to this scheme (0 ° C → 1 ° C → 2 ° C → 3 ° C → - 3°C →
−2°C → −1°C → return to 0°C)
...... FRE REC A/C
+3°C OFF ON ON
+2°C OFF ON OFF
+1°C OFF OFF ON
=0°C OFF OFF OFF
-1°C ON OFF ON
-2°C ON ON OFF
-3°C ON ON ON
If you need it colder in the cabin, then choose negative values.
If T is not maintained at all, check the T sensor (to the right of the steering column). If you heat it up, then cold air should come out.

On mine, it works, my set up is -2.
Bardon the stupid remark, but is the fan speed knob in the uk on the right side?
Instruction is for the left hand drive.

It is.

Can you change the temp compensation setting?

I have heard that ca 25g in a year is acceptible loss of the gas.

T31 X-trails take 450g of gas, so it takes ca 10 years to loss the half of it. The system pressure would be still there to turn on the compressor, but the cooling efficency would be low. Last year I went to AC service and they sucked it all out with the service machine and just few grams where needed to top it off. I went to a garage that had a base cost+gas +oil. I paid almost nothing for the gas and oil.
In the ideal world you do this every 3-5 years just to be sure.
