I was driving 225 miles to Columbus, Ohio a few years ago in my 1999 BMW Z3 convertible when the CEL came on. Temperatures were in the single digits. I had significant concern about a breakdown in those temperatures since many of the miles in Ohio and in Kentucky are a long way from civilization. A repair shop convinced me that I need not be too worried and in fact I did get there and back home with the light on but no other problems. As far as I remember, the problem was not serious, but I bought a code reader right after that!
