My BMW uses a 3-wire Bosch O2 sensor also.  I discovered about 2 
years ago that theBosch 3-wire for the 87 Ford Mustang is the same 
one for the BMW. . . . but a lot, lot cheaper (about $55.)  I would 
suggest you go to a FLAPS and look at the VW one and the Ford one and 
I'll bet that there is no difference.  The Ford Bosch has worked fine 
in my BMW w/ no problems.  Many, many members of the BMW-Digest use 
this solution on their cars.

Happy Motoring,
