All of a sudden I get these codes, I have a09 535i n54. It’s FBO, upgraded turbos, everything upgraded or replaced almost. I have checked fuses, tried reseting throttle adaptations, erasing codes, codes won’t erase, flashing to stock and back to custom, etc……. Any help as I have searched the internet up and down but it has been different for everyone with no similar solutions.
I am lost. Please any and all help is appreciated.
