    Found something interesting.

    If I turn the ignition on before I start the car, I get the code, but if I go straight from key insert to start without first turning the ignition on, then I dont get the code. Normally I turn the ignition on before starting the car to let the fuel pumps prime the line (the enable on my controller is tied to ignition, but the BMW normally turns the fuel pumps on when you unlock the car to do the same (without the ignition on, but with my custom LPFP setup it doesnt)).
