Which situation we need to coding and which don’t need?
There are many variants of FRM(Footwell Module) FRM1, FRM2, and FRM3 which all have different controls and functions such as lights, windows and doors. If the eeprom data is exactly the same as your car original data, you do not need coding. If fog light or aperture still flashes after load original data, you need to do coding.
Device optional:
BMW ICOM Engineering software Ncs expert, Launch X431 V pro, Autel Maxisys Pro MS908P etc
Here is the instruction of Launch X431 Pro, it is easier than ICOM engineering software.
