My 2013 Z4 has a mind of its own. At random time, the seat heaters turn on, at other times when I do want seat heaters on they don’t work. Also notice that the lights for up/down activation of top don’t work, but top does go up/down just the light on the center panel not active. Is there a interior control module that the two of these problems can be tied back to? Any ideas on what can be causing this?
