If the "Telephone" option is not displayed on the main navigation menu, then the TCU is either not connected or it has failed. Based on the date of manufacture, that TCU should have the Bluetooth feature, but I am not as familiar with the European TCU modules.

Check its plugged in firmly and that the fuse isn't blown. If the unit doeasn't have power, the car wont know its there.

Did anyone have probles getting a TCU into pairing mode? Some people in this thread report the need to plug in the eject box temporarily to get pairing to start.

Maybe this extra step is required?

1) Turn Key off and then to KL-R or KL-15. 1.
2)The vehicle is ready for pairing for the first 2 minutes of key on. 2.
3) If the R/T button on the MFL is pressed, "Activate Phone" appears on the MID or Board Monitor. For the E53 X5 the seatbelt needs to be plugged in and the R/T button pressed on the MFL and "Activate Phone"
appears in the Instrument Cluster.

Press the "R/T" button on the steering wheel emulator in NavCoder

I think I need to try it in the car, if it ever comes back from the mechanic...

It is possible that a European TCU uses the pairing button in gibbo_ireland's situation. Or, it is just as likely that gibbo_ireland had a ULF and not a TCU. I vote for the latter. Every BMW document I have read and everyone else's documented experience I have read states that the TCU goes into pairing mode every time you start the car.
