F30 Ihka low to high panel - jaki - 15-08-2023

I know that basic aircon in F3x is single zone and high dual, but.
Has anybody managed to code it that I can make high panel to work in low aircon car?
Naturally it definitely would not be dual, but signle only. That's ok for me.
A car I'm planing is from 2012 to 14 model.
Why I'm asking this:
I'm planning to buy a car without seat heating and there are very few low panels for sale with seat heating buttons. High panels dozens.

Send me svt_ist and fa and cafd backup from IHKA,FEM and HU we can try

Ok, I will, if I end up with that kind of car.
Winter is coming, but fortunately not in a couple of months, so time to solve these challenges is enough.

Doesn't work, because of missing servomotors. Whole system will be unusable

I'm worried that You are right. Even with coding probable it will never work ok.
People have managed to work it allmost ok, but that is not enough. Specially that blow directioning (aka servomotors playing) is missing and that's it.
I was surprised that so many cars are in market with simple aircon and without seat heatings.

I've have a F36 standing here which wants that retrofit. Car has now basic klima and wants ikha3 (digital panel).
It is doable and the display will work accordingly to he buttons pressed but as said above servomotors are missing.

What if IHKA ecu would change also?
Just leave missing actuators unconnected.
Still saves the biggest job = heating unit replace


RE: F30 Ihka low to high panel - Fx82 - 16-08-2023

Which ihka ecu ?


RE: F30 Ihka low to high panel - inspi1981 - 16-08-2023

There is addressing for sermotors, diferent on low and high IHKA.
Because of that will unusable until all servomotors are present

But, if we change all the present servos for right address ones and leave not preset connected?
Then heating "should" work like passenger side motors are failed.
Hmmm, we are not so far away that se change the whole system.
Still, complete heating unit changing is quite, job.
