Thanks for that, I compared but didn't find any real differences.
I think it might be my programming setup has put wrong vo defaults into the DSC
I have come up with a workaround, so if I VO code the DSC and KOMBI to $544 (with $540 removed) and then change
ACC_AUSSTATTUNG to wert_03
Then I get cruise control with braking, but I don't get the cruise popup display in the cluster that shows the set speed. Otherwise the cruise control works and applies brakes down hills.
Not ideal but at least it works. I will see if I can play with the DSC options with the dynamic cruise and see if I can get a working default.
Otherwise I will try and reinstall BMW standard tools.
