Also interested in enabling TJA! We didn't get it here in Australia either. Also heres some steps someone on OzAudi used to enable TSR, worked for me using OBD Eleven
Coding for FL
After a bit of trial and error, and thanks Wood Duck for pointing me in the right direction, I got TSR to work for the FL as the coding for the pre-FL did not work. The coding below has a few more steps and is a mixture of steps from various forums and one or two personal additions. For the pre-FL coding, byte 1 and bit 0 had to be enabled in Module A5. But the FL already has it enabled. So after the normal coding didn’t work the first time, I deselected it and started the coding again. However, I’m not sure this made a difference. I believe the last two steps added made the difference. An error message comes up when you start the car, and the TSR option in the MMI is greyed out, but it works and hopefully it'll work for those daring enough to try. Try at your own risk

I also used the coding below for the FL (slight variation to the pre-FL)
