MFSW mute using obdeleven?

Anyone know how to change the voice-command button to a mute using the obdeleven? Can't seem to figure it out using the instructions for vag-com. Can't find a steering wheel module setting that allows for byte checking/unchecking. Would appreciate the help.

can you look what coding is there , in controler 16 ?

Sorry, disappeared there.

I believe the 'Steering Wheel' (16) is labeled 'Steering Column Electronics' in OBD11, but when I hit coding I only have the option of adding a new value (currently 0000732) and not individual bytes and bits. If I do have to put a new value in what would that be? Would appreciate any help. Thank you.
