I have a 2007 E92 w/6 speed manual with 103K. Recently the display for the OBC (miles per gallon, date/time, distance, etc..) has been randomly and continually changing in my display. Turn Signals work fine. I've tried to clear it out by cycling through the displays, but it always comes back Temperature or conditions don't make any difference. The battery is new. Can't find many discussions reference this issue and most suggest that it is the Turn Signal/OBC stalk itself that may be bad. Not sure if I should have the stalk replaced?
