I show you my Check Engine Light For my BMW it shows engine code P112B this is a low coolant engine code, filling up your reservoir will fix this code and it took about 5-6 starts of the engine before code went off. Check for leaks in your reservoir or your radiator. The car in the video is a BMW 2002-2008 E65 E66 745i 745li 750i 750li. Thanks for watching.
