M40i Display Brightness

The speedometer/rev counter display brightness is erratic sometimes dimming to almost zero despite normal daylight ambient light outside. Also, the dimmer knob for night time brightness adjustment has no effect with the headlights on. I'm still waiting for the English language manual but it seems that no manual daytime adjustment is possible. Has anyone else had this problem?

Off to the dealer tomorrow.....

EDIT: Night time dimmer knob now working - seems like an intermittent fault.
