Question X5 E70 IHKA Basic to High retrofit

Hi all,

I've swapped Air conditioning control module (IHKA) from basic (digital mono temperature) to high (2-zone temperature) and all buttons seems to work, but heating works in phases so its heating to set temperature then stops and heats again after while, blowing cold air to legs. It doesn't seems to keep constant temperature the way basic module did.
Is there any codding needs to be done like adding $534 to CAS and FRM or changing coding in IHKA module from Basic to High (I can see there are 3options Basic, High 2-zone, High 4-zone)?

Thank you.

As far as i know it is not possible, because high IHKA got 10 flaps and basic got only 6. Maybe you can code it, but it can not work as IHKA high. Check wiring diagram...
