And how do you fully switch off the auto climate control? I realise there's no 'off' button. Should i just put it to manual, and bring the fan speed down to minimum?

No, the battery doesn't have to be fully charged, just hookup the charger to the car and flash, that's all that's there to it.
After bringing the fan speed down to minimum, press the low fan button one more time and the climate control screen turns off. That means it's completely off.
Mate, I flashed mine without using battery charger, I just made sure all lights and other electrics are completely turned off. Worked like a charm!
Battery charger is recommended, but it's not must. Because most owners have weak or old batteries... etc. A new-ish healthy battery should be able to sustain constant power delivery to the DME & TCU(EGS) modules throughout this whole flashing process with absolutely no dramas.
