What is BMW Coding?
BMW Coding is used to customize settings so a vehicle operates more as the individual desires.It is a really great way to customise your car, and enable features that the car didn’t have from factory, but it’s also very easy to screw things up!
Repeat step four for any addition BMW key fobs that need programming. Insert the key into the ignition to finalize. These instructions apply when you change the key battery or your BMW key has stopped locking/unlocking the doors, but the key starts the car.

BMW Coding Risk:
Just like jailbreaking an iPhone or any software mods, the warranty of the vehicle could be voided by coding. After all, it is a third-party intervention to the computers of the car, without the manufacturer’s approval. There is a risk that some systems might get broken if the operator does not do everything properly. Car coding should never involve an “I’ll just wing it” strategy.
There is also a risk of permanent damage to a vehicle’s electronic systems. In the worst cases, one of the car’s computers could receive irreparable harm and require replacement.
In most cases,it is safety to coding for you BMW.And before you coding,you would better to ask some question or search the features you want on google.There are many BMW coding forums,join them to talk about the coding topics.
