Bluetooth Telephone BMW E53 X5 2005

[TAIX5]

Hi all

Apologies if this has been discussed and I have searched and read a few threads but just looking for further advise.

Having bought the above car and fixing the small niggles these cars have. I am now working on fixing the Bluetooth pairing issue I have.

I have tried all combinations of trying to get the car to show pairing (holding the center console button and IGN 1 and 2) but it always say's activate phone and nothing is appearing on the phone. I have tried 3 different phones.

I have also used the BMW Scanner software are cleared the current sync'd handsets and also tried pairing through the software where you enable pairing and nothing.

I took it to a local specialist who checked all connections and concluded it is the Bluetooth module that has gone.

So I looked in the back and saw the silver unit bolted in at a angle which I removed on the side next to the SAT NAV, CD player etc. However I am confused is this the unit that needs replacing and is the ULF or is this what they call a TCU and if so is there somewhere else I should be looking. I have included a few pictures of the silver unit. Also looked on ebay and they seem to look a lot squarer in dimensions then what I have.

Many thanks
