In first instance try to disconnect the unit from the mains and reconnect 15-20secs later 8 times out of 10 it helps. otherwise you might need to reprogram the unit processor which is more complicated and requires knowledge and understanding of electronic principles, assembler, also some devices to perform the task.
Otherwise I'm not sure about exact model of your ECU (computer) but in some cases it also gives the access to reprogrammable radio unit, so in this case laptop, one simple program (u can find it as free downloadable .exe file) and special diagnostics cable wuold sort everything out. But as I said not all ECUs offers such an option. And if you'll go for this step you need some knowledge about electronics and soldering as you'll have to build the cable I mentioned, as tu purchase one would be quite painfull for your vallet.

Hope it helped although if you need any further information just drop a line here.

I HAD THIS SAME ISSUE. I TOOK OUT THE REAR PANELS INSIDE THE TRUNK. FIRST, START WITH THE LOWER CENTER PANEL RIGHT WHERE THE LOCKING LATCH IS LOCATED. THEN, MOVE TO THE LEFT PANELS ON THE SIDES OF THE INSIDE OF THE TRUNK. ONCE YOU HAVE TAKEN OUT THE PANELS, THERE'S A SILVER BOX IN THE TRUNK WITH A "PK 0000" NUMBER PRINTED ON A STICKER. THAT "PK" NUMBER IS YOUR CODE.
IT'S NOT AS BAD AS YOU MIGHT THINK TO TAKE OUT THE PANELS, I DID IT IN ABOUT 15 MINUTES. JUST TAKE YOUR TIME AND THEY ALL GO BACK IN AS EASY AS THEY CAME OUT. JUST TRY NOT TO FORCE ANYTHING BACK IN IT'S PLACE.
HOPE THIS HELPS. LEONARD-

SOURCE: Finding the PIN to pair My iphone with 2006 BMW 750i.

I have the same car. The dealership wanted to charge me $155 to go into the computer and give me the passkey.

One of the techs just told me how to find it myself:

Inside the trunk, on the left side behind the DVD player, there is a box that sits at a 45 degree angle. Right above that box, there is a box that is shaped like a VHS tape. Unscrew that box and on the other side you will see bluetooth PK: and your four digit number.

That saved me $155 dollars and now I can talk hands free through my car.
