This is strange - the HBA receives the command to activate via CANbus. In the dash (where the symbol should be) 17-Instruments there is a fault "Function Restricted due to Interrupted Communications"? Worth to investigate?
As I'm not owner of a T6.1 I don't know all the fancy things available - can you set "user profiles" somewhere - in Infotainment unit?
In one of the profiles the HBA is set as "not active", as well as light intensity setting deviates from the others? The profiles 1 & 2 are not from factory.
