I am working to enable rear fog lights on a 2021 F56 Cooper. This has been covered in the past elsewhere in the forum. I have replaced the panel light switch with the version having a rear fog light button (step 1). The next step is to add the rear fog light option (5AA) to the VO. Up to now I have only used Bimmercode to alter coding. It would appear that that app does not have the ability to change the VO. Is that right? If so, do I have to jump to E-SYS to do this? Or is there a different preferred coding app?
