So do you have the pre-heating option or do you want to add it too? For this you have to change ZCS, then code IHKA and instrument cluster. Then you manually (FSW_PSW) have to change IHKA coding for change over valve because a version without pre-heating from the factory does not have it.

The thing is I have an android head unit with iBus. I'm not sure what system it had originally. I have the option for aux heating in iBus.
Also I live in Cyprus, so it doesn't really go below 6 degrees C apoart from some winter nights. I understand the pre heating is only supposed to work below 6C but I thought the aux water pump should be running when the car is at idle to circulate the coolant through the heater core? basically when I'm at idle the heat in the car drops significantly
