I was recently on my way home from Tennessee to Florida in my '16 M6 when I had a CEL pop with four codes (U113F, U1140, U02A9, P026E). I know these are for the two exhaust valves and the charge air cooler, but I'm assuming that since these things are unrelated and they all came on at the same time that they must share a common sensor connection somewhere. Does anyone have an electrical diagram or happen to know where these lines may meet so that I can check it out? I haven't noticed any abnormal temperatures since this happened so I don't think I'm having any cooling issues, any advice is appreciated!



Took a little detour on my way home to hit the Cherohala Skyway and Tail of the Dragon - I had only been there on bikes before, she's a big girl but she handled herself well!
