I have a issue with the system check light. Our BMW used his diagnostic tool to check on the issue but he got 158 code which is not in his manual. I thought it was just bad gas and only started putting premium in the tank. That help for a little while but the light came on about a week. Also could you help me figure out why my cigarette lighter don't work. I am not sure which fuses is for the instrumentations or accessories for this function.
