Hello everyone,

Seeing as I've been searching for some time without any success, I will bite the bullet and post my question.

Can I upgrade my AC control unit with an automatic simple climate control unit. Pictures for reference

My unit

What I want to install

Any help is much appreciated.

So I've decided to give it a go and code it all on my own. Done everything. Coded my start-stop system to remember last setting.
Then I started doing my aircon panel. I managed to code it, fitted it and... no success. It doesn't do anything.
Only the middle light above the fan speed buttons is illuminated and that's it. Can't do anything. Can't change fan speed, temp, nothing.I tried IHKA_1Z, tried also IHKA_2Z but still nothing.
Could it be that the panel itself is damaged? Or maybe it's not compatible with my car at all? What is your panel part number? Mine is BMW 6411 9384046-01

Any ideas? Thanks

I got exactly the same and I am very curious about the outcome.

After checking on realoem it looks like that part no. is from the LCI model which may mean it's not compatible? What year is your car?

I'm sure it is. As soon as I coded IHKA_1Z my original manual panel stopped working properly. I then fitted the new automatic one, which only displayed one light in the middle and nothing else would work. Tried coding different IHKA's with no success each time.

Did you fit it first then code?
No. Coded first then fitted.
When it didn't work I tried coding again with the part fitted but still nothing.
Then I coded back my old part and fitted it back after coding. This one works as it should.

Should I try again by fitting new part and then coding it? Is there anything else I can try?

I only coded it before fitting because I was coding my start stop system so I thought I'll code this too while my laptop was already connected.

Other thing is, while my start stop coded with engine off, I couldn't read coding data from IHKA so I had to try again with engine running. Should this be coded with engine off or on?

It does my head in this thing. Got too excited about geting automatic aircon a bit too early.

Did you get this sorted? I've just fitted and coded mine and have the same problem :/

The fan is working but just the middle green light is illuminated and none of the buttons work. I fitted it first and definitely coded correctly, any ideas before I revert back to the old part??

Yeah in my case I had to return my control panel as nothing would work. Then I've found one that came from 2013 F30 and that one worked right out of the box, quick coding and it's been working great since then.

Damn... looks like I will have to return mine as well then and source another one.

It was removed from a 2015 BMW 2 series, part no. 64119384052. My car is also a pre-LCI 2013 so looks like I'll have to look out for an older part.

Try to speak to Ogb666, as he might have a solution which could possibly work on your car.
Will do, cheers. He's helped me a lot previously so I'll hold fire returning it for the time being.
You need part number 9287342 for the black surround or 9287344 with silver surround.if the controls aren't working and only the middle fan light illuminates it means it's kcan2 and won't work

That's what I've now figured unfortunately but thanks for checking.

No worries there maybe another way to get it working by tapping in to your emulator to get the kcan2 signal pm wibbles and he'll confirm

Hey,

I'm also stuck with this - mines a, gives the same kind of response, green centre light with fans on but just blowing cold air. 61 plate F20 and the manufacturing date of the monozone AC unit is July 2014 - I'll PM wibbles.

You'll need one of the part numbers above as you don't have the emulator like fez.

If Wibbles can sort you out then go for it. Alternatively just send back the part and source a different one with the right p/n.

It happend to me with the HU_ENTRYNAV and would have saved me so much time if I would have done that straight off.

I know this is kind of off topic, but what was the problem with your HU_ENTRYNAV?

I've just bought one that's all singing all dancing, but I'm waiting for the emulator to come for the nav before I got it...

Is this the same emulator we use for navigation?
