Have a 2004 X5 e53.

i Cant get the bluetooth to work. I have tried everything, even changed the TCU/ulf modul. From 2004 to a 2006 TCU.

When doing the procedure, i get no flashing lights. Cant find any units.

Another strange thing, i bought a snap in adapter aswell. There is no power on the unit, the phone won't charge.

Any ideas? starting to get confusing!!
