Installation Date : 02 September 2017
I know people have already retrofitted LCI's in F30's and F31's. I just haven't seen a DIY for the F31, so id like to contribute to the forum.
NOTE: Like any DIY project, proceed at your own risk. I am not responsible for anything that happens to your vehicle as a result of attempting this retrofit. This information is simply posted as a reference to help others who may wish to do this project on their own.

Coding is preferred to avoid bulb warm up test. I activated rear fogs and got a warning on the idrive. After coding it was cleared. :thump:
