Hi Karl
Welcome to the forum. The multi function tail lights for the R1250 bikes are supported as they are still on an older version of the body controller. The R1300 however, has the new body domain controller, which is not yet fully supported - we are constantly adding R1300 diagnostic features as they become available, but most of the R1300 generation coding features are now blocked by a secure coding requirement from BMW.
Unfortunately that means at present we cannot provide the combined turn/break indicator coding feature as on the previous generation.
Kind regards
Ruan
