I mean, can bluetooth be activated in an European LCI E60 by just upgrading/adding bluetooth option by computer in service? I think there are BT capabilities built-in (TCU). And no, I don't have BT option from factory (I wouldn't be asking if I had), and it's not standard here in Europe.

I dont know about the part numbers of the TCU but this is what happened to me. I own a 2004 530i and the build date is April (04/04). I had seen a bulletin which said cars with build date between 03/04 - 08/04 have the hardware capability to support bluetooth. It just requires a software upgrade. Also, these cars are require a programming update to play MP3 from their in dash CD player. Based on this info, yesterday I went to the dealer ( Rockville, MD) and got both these updates. To my surprise both came free under warranty. Actually, only the MP3 update was free but since they were doing a software update they updated the Bluetooth option also for free.
Have attached the MP3 Service Bulletin you can refer. Also, below is the extract from the Bluetooth Service Bulletin SI B84 13 04.

For E60/63/64 vehicles produced from 3/04 to 8/04, Bluetooth? functionality can be added to most of
these vehicles by updating the vehicle software using CIP 13.2 or higher. After this is performed "Retrofit"
of "Tel Bluetooth" needs to be performed. Follow the procedure as described in this Service Information
for "Activating Bluetooth" and "Pairing the Handset". Vehicles prior to 3/04 would need to have the TCU
replaced with the 2005 MY TCU at the customer's expense and the vehicle updated to CIP 13.2 or higher.
Phone docking cradles may not be added to these vehicles because of wiring incompatibility. Note: This
software update and retrofit is not covered under warranty and is at the customer's expense.

I was able to play MP3 from my in Dash CD player and also pair my iPhone.
Hope this helps.
