this image explains how to get into the aircon diagnostic system (click on the image to enlarge)
The only "difficulty" ergonomically speaking is that, when in diagnostic mode, you can't see the "target" temperatures in the upper display (satnav car, which you have). This is because the upper display shows the value from the selected sensor instead.
Best thing is to practice "blind" setting the target temperatures when in normal mode i.e. start with the target in LO then count how many presses of the red "up arrow" it takes to get to HI, so that you can set any desired target temperature "blind" by counting the up/down presses from LO.
Then set the target temperature to LO, switch off the engine, and follow the instruction in the image above.
You can drive the car while the system is in diagnostic mode and look at any sensor.
For "sensors" 6 and 7, as you change the "target temperature" (blind) you should see the flap % change.
Sensor 9 is strange, I think it is "virtual", and is a function of "target temperature" minus "in-car temperature"
