Here is a compilation of BMW factory info about the different coding plugs, but you know what? There is 1 combination left not listed on this chart, so I did a little more research.

In case you do not see it - there are 8 possible ways to connect the common pin 30, with the three other pins.

Code:
   1)  30   --
   2)  30   86
   3)  30        87
   4)  30   86   87
   5)  30             87a
   6)  30   86        87a
   7)  30        87   87a
   8)  30   86   87   87a
One of the 8 possible combinations isn't listed in the chart above.

A connection between pins 30, 86, and 87a

It is listed by BMW as 'Special Plug', and is part number 71 60 7 659 547
