There r only three ways of obtaining the passkey of a genuine BMW B/tooth setup.

1. On the white card in the book pack, which l guess u no longer have.
2. By means of diagnostic computer which can communicate with the phone ECU, most likely a visit to the dealer.
3.On the sticker on the outside of the control unit.

l guess u r not looking to pay for the dealer to find it for u (unless u bought it from a BMW dealer so would be free) so ur only other option is to access the control unit & find the code on the white sticker on the outside.

The phone control unit is usually located behind the left hand carpet trim in the boot.
