Hello everybody, my name is Matteo and i'm from Italy.
I've followed you since i decided to buy my F22, but now i decided to actively partecipate at the forum, hoping to kindly recieve the support I need.
My F22 is well equipped, but I've always missed the dual zone A/C control, instead of my single zone automatic control panel. The last week i purchased a dual zone A/C control panel for a few bucks , in order to try to fit and code it in my car (doesn't matter if at the end I will just obtain a single zone A/C with a dual zone control panel, I just like the control interface, in my opinion a lot better than analogic).

So, I proceded in this way:

- installed the new dual zone control panel
- Using E-sys I made this steps: read FA -> activate FA -> read SVT -> find IHKA ECU -> right click and 'code'

Unfortunately this didn't result in a success, indeed the panel switched on but was out of control.

So I would ask some questions to more skilled users:

- did i proceeded in the 'proper' way?
- should I do in another way?
- Have I to disable some checks or to delete errors after the installation?

This evening, exploring the CAFD file inside IHKA ECU i found some interesting options:

3000->Luftverteilung [you can choose between Manual, 1Zonig (default) and 2Zonig]
3000->klimageraet [air distribution]
3000->solarsensorkennlinie [characteristics of the irradiation sensor]
3000->blower_type
3001->besclagsvermeidung [fogging prevention]
3001->solarsensor -> default not active
3001->MSA_schubansteurung (fan speed control) -> default not active
3001->KMV_aktiv_beschlag [fogging prevention] -> default not active
Not shure if these codes means something for dual zone ac function

a big thank you to everyone who will try to answer me

Ha I'd love single zone climate control...

The need to have both matching all the time is unreal...

Drives the OCD crazy. Only upside is in the rare occasion GF and I take my car instead if hers it minimizes bitching. She's "that age" so temp sensitive. Truth be told I turn her seat on when she's not paying attention to mess w her.

If you originally had the single zone control unit with rotary switches then the transition to an auto A/C system requires much much more than just replacing the control panel. It's a dashboard-off job. Surprisingly, a fellow forum member did this retrofit on his F30 and you can see his post here http://f30.bimmerpost.com/forums/sho...45&postcount=5

Thank you very much!
What exactly was I was looking for but unfortunately I was not able to find.

Ultimately I do not care to have a real dual-zone climate control (the cabin is one and fluidoynamics excludes the possibilty that there are two different temperatures), but I would try to operate my air settings through the dual zone panel. According to a local professional retrofitter this should be possible ..
The second week of February I will be to him and try, then I will update you with the results.

Here I am guys. I went to the installer and the answer is: not possible to retrofit the only panel
Maybe i should try a panel with a code compatible to the period of production of my car , but for the moment i have other projects in my mind (10.25" screen)
