Hidden menu of MMI3g

[H5N1]

Hi,
Ihave activated hidden menu on may car to activate this battery level menu point on MMI.
After I have done it I lost clock from MMI screen there --:-- just shown instead of time and in MMI menu "Time" I can only adjust date and time formats. Options to change time and source of it have lost.

Can someone help?
Car is A6 C6 from 2009
