Hack E46 Bluetooth passkey?

Just bought an '05 M3 convertible. The previous owner was (un)kind enough to not leave me the Bluetooth card, and checking the Assist module, I cannot see the sticker (at least from the side facing into the trunk when the rear left panel is removed.) When I try to pair w/ my Razr V3c, it discovers "BMW09210", but of course won't pair to it without the passkey. I called the dealer, but they can't schedule me for a non-critical service appointment for about 2 weeks! Asked my service advisor to take mercy so I could enjoy my new Razr (that I bought to go w/ this car!), but they didn't know offhand how to pull the PIN. He said someone there can figure it out when I come back in two weeks. So, any ideas? Any BT sniffer/hack programs that can pull the 4 digit pin? Are there standard pin numbers they always choose from (1234, 0000, 8080, etc...?) Anything I can do to get the PIN from that discovered name or the Mac address?

Are you sure that there is no sticker in the TCU? http://www.bimmerfest.com/forums/att...0&d=1122235251

Not on the visible side. See that sticker strip on the bottom right? The thin one with the colored squares? Dark blue, purple, medium blue, then a lighter one at the top? That's all that's on there. Nothing more unfortunately.

In either the TCU or ULF the dealer can pull the passkey using the DIS computer. BOTH have a sticker on them with the passkey.

It only takes 4 screws with the TCU and 3 screws with the ULF to remove and read the passkey.

Here is how to remove the TCU or ULF to get the passkey

Ok... that's weird. What about the other side? A sticker with part number/Pin and the rest of the TCU info should be there...

This pic (taken by someone else in their instructions) is exactly how mine looks. Think it is worth taking the module out and checking to see if the sticker is on the other side? Is it a pain to get out?

Won't work. They have individualized passkeys which are printed on the ULF sticker and on a card, neither of which the original poster has.
If there is none, then a trip to the dealer is your only hope (or a lot of trial and error for a 4 digit passkey)

Four screws (I think that they are 8mm) are holding that sucker there... it is worth a shot, or you can always can go to the dealer.
