Reduced power engine malfunction error. This error disappears upon restart

Hello, Intermittent problems, especially intermittent problems with false symptoms, are difficult to diagnose. Especially across a computer. You will need a technician with factory diagnostic software to identify what is going on the quickest. Either a dealer or independent factory authorized BMW shop will be your best bet with this one. Side note, My daughter was born at St. Davids when I was stationed there. I almost bought in Round Rock.
