As a former MINI R53 owner, I know that BMW product required updating via software to enable the rear fogs.
So, I thought it worth checking to see what the hassle might be on a E90.
No coding required, just modify your current switch or buy a new one that has the symbol and lights up like oem. Just swap in and it works right away. I have one from ECS tuning and it look and works great.
