Hi guys, on my car I used to own a while back someone used esys to do some coding. He coded in that the mirror turn signals were used as US sidemarkers and that they would turn on/off when unlocking/locking the car. When the car was started they would turn off. I want to do this again on my M140i but can’t find out how. When using the non-expert mode I can get the lights to work but they don’t shut off when the car is turned on. Does anyone know how I can fix this?
