Usually any parts store, such as Western Auto, can reset it for you. Keep in mind, a lot of the times the parts store's reading equipment cannot read the BMW code and therefore can not diagnose an exact problem. They sometimes just get a code number/reference number in ehich case you can call the dealership and they will tell you what's up. However, they can reset the light with no problem.
