Hi,
this is one topic I found in one other forum regarding retrofitting the same AC control panel ->
https://www.motor-talk.de/forum/touch-kimabedienteil-t6806095.html
Let me try to sum it up for you and translate it into english:
There are the following models of the AC control panel:
3G8907044 without seat heating
3G8907044 A with seat heating
3G8907044 C with seat heating and parking heating
3G8907044 D with seat heating and seat ventilation
3G8907044 E with all of the above (seat heating, seat ventilation, parking heating)
Coding example (hint - use experimental coding, you might find additional information that you need):
Address 08: Auto HVAC (E87) Labels:* None
Part No SW: 17G 907 044 H HW: 17G 907 044 H
Component: AC Automat 211 R676
Revision: 20K06000 Serial number: 00000A00811063
Coding: 00020004200010010004200000101522
Dataset: EV_ACTouchPrehVW37X 001008
There might be a need to "relearn" the compressor logic: -->

- Code the controller as mentioned before
- Erase the error codes ()
- Close the controller
- Open the controller again
==>Start:
- Check error codes again, you should have something like: First run of compressor not carried out and no initial setup
- AC control unit must be turned on (ignition)
- go to Basic Settings and there choose "adapt flap end stops" + Start
- It will say that it is not running, even though it is
- Check the AC control panel, some LEDs will blink
- Wait until LEDs stop to blink
- To be sure wait for another 30 seconds
- press "Stop" button in to stop the routine
- **immediately start the "Compressor run in: automatic start" routine
- It will take around 2 minutes, engine RPM will be changed and LEDs will blink again
- will show when the routine was finished successfully
If during the step ** some error happens do the following:
- you don't need the Security Access for this
- Go to adaptations, search for "run" and press enter
- Check the IDE01503 and IDE03176 adaptations
- Values of those two adaptations could be 0 60 or 120, write 120 and take it over for both channels (do the takeover even if 120 is already set as a value, we want to overwrite those adaptations nevertheless)
- Close the controller
- Ignition off
- wait for some time (1 minute should do)
- Ignition on
- go to "==> Start" and do it all over again
Hopefully I translated it right, feel free to use google translator to double check it.
Offtopic part:
Few days ago I got one Passat as a lease car for a business trip. It had that AC control panel and I really really hated it. It was not too short trip, around 6 hours of driving and I had to change few times temperature in a car and could not do it as comfortable as turning the knob, instead I had to look away from the road and click that stupid touch screen without any tactile nor sound feedback. I hated it so much that if it would be my car I woud retrofit the old style control panel with real buttons and turning knob instead of this cheap-to-produce touch panel... If you care only about the looks go for it, maybe you just need some time to adjust and be able to use it without looking... I also hated the infotainment touch screen without any side buttons except "home" and "menu" but that is another story...
