Today I got in my car and noticed a warning Icon on my Tach. The icon pictured was the rear of the car focused on the passenger side with what appeared to be a light bulb in the upper right corner over the car. I looked in my book and couldnt find what it means. I figured it was perhaps a burnt out light in the rear, absolutely nothing is out. It Icon on the OBC display (tach) eventually went back to the mph setting, However the very next day the darn warning came on again, but went away....ANY IDEAS?

 

I'm not sure of your options but perhaps tire pressure? I don't know what the display looks like on a non-NAV equipped MINI when the tire pressure is low but the newer TPM system is supposed to indicate the tire that is low on the NAV unit. Could it be the TPM (Tire Pressure Monitoring) that triggered the display?

 

Could it be something to indicate possibly slick or icy roads (the car sliding and the light bulb being a thermometer)? I'm just grasping at straws.

 

Maybe this?
