Good day , With me it has happened for the repeated time when I press the Mode button during the ride from the radio (audio system in the left side panel ) ,the ignition completely runs out . Engine runs however , all ads in the cockpit , tachometer , tacho go out for about 30 seconds . After that both pointers from the rev meter and the speedometer hit again and everything is back to normal . Had the last year before . There was deleted the error memory at BMW . Was nothing in it . Should it watch . Now I had the problem again . Has someone had such a thing in style ? Thanks for your answers ,Help
