Climate controls gone after MMI upgrade

[cebo0650]

When I got my 2006 A6 Avant (used) it had MMI version 0600 (0.6.00).

Changing the temperature or fan settings would show the action on the MMI screen. Pressing the Setup button would also bring up a screen where all the climate options could be adjusted.

After upgrading to the latest North American MMI version 4610 (4.6.10) any and all controls are gone. Temperature and fan settings are no longer shown on the MMI screen and pressing the setup button on the AC panel does nothing.

Can this be fixed in the hidden menu?

I found the solution myself so I though I would post here for others. I went to see a friend of mine who is an Audi/VW mechanic.

He didn't have time to play around with me but he did give me his cable (Ross-Tech) and laptop. Took me a while to figure it out, but I was able to fix it.

Once you're all connected with VCDS go into [07] - Control Head Front, and then click on Adaptation. Then select Channel 11.

According to the Ross-Tech the setting for Channel 11 are as follows:

Channel 011: Additional MMI Options
+00001 = Owners Manual available
+00004 = Frequency/Source Change via Function Button active
+00016 = Driver Information System (DIS) installed
+00032 = Climate Control Comfort available
+00064 = Auxiliary Heating available
+00256 = AUX-IN installed

The initial value in Channel 11 for me was 4, adding 32 makes the new value 36. Therefore I replaced 4 with the new value 36, clicked Test, then Save.

I then turned off the car, and started it again, but to my disappointment this still didn't bring back the Climate control settings. My buddy suggested I reset the MMI, which can be done my pressing SETUP, BIG KNOB and top right soft button together.

Once I reset the MMI the Climate control settings were back!! :)

In summary:
- Go to [07] - Control Head Front
- Go to Channel 11
- Add 32 to existing value
- Test and save
- Reset MMI by pressing SETUP, BIG KNOB and top right soft button together.
