Coding your car means changing different configuration entries of your ECUs (Electronic Control Units) of your BMW. You may activate a digital speedometer, auto fold your mirros after locking your car or customize your “Welcome Light”. If you have bought extra white lamps for your Angel Eyes you can increase the voltage and this way the brightness / whiteness of those lamps, so they don’t look yellowish.
If you maintain your car yourself, you can reset your “In-Control Messages” within the iDrive and your service times within the on-board computer. So you can change your oil or brakes yourself and reset the messages so your car knows that you have changed it, instead of warning you every time you start your car.
Sometimes it is useful to monitor your engines parameters while driving to analyse an error that only occurs once a while. Also you can check them while driving hard on the race track.
