Thinking SA633 was somehow not compatible i changed it to SA638 and re-coded the M-ask2. I now see an SMS menu but still no Bluetooth.

i don't want to try SA644 as that's for a MULF not a TCU.

in the i-drive settings menu there is an option to activate bluetooth but it wont let me tick the box.

I've checked the MOST connector at the TCU and there is a red light(i though i might have disturbed the most connector)

Any ideas what to check or do next ?
I cant diagnose the TCU via INPA or read it's coding via NCSexpert so is it a physical communication issue i wonder... ?

I`ll check with ISTA-D later if there is a break in the MOST loop.

Couldnt wait till i got home, had a play with it in work. removed the glovebox fibre loop and re-connected. bluetooth started working again but the sound is cutting in and out (radio/CD/BT etc...).

so i likely have a break somewhere in the MOST loop or a failing TCU... funny how it happened after i swapped the M-ask. no pinched cables that i can see.
