I have an Euro 1984 635csi and the OBC is all in german. Does anyone know the traslations or have a diagram in english? The speed alarm is driving me nuts

Unfortunately, I don't think that you can change the lanuage on the older OBCs. The dealer could probably either flash the firmware or replace it for $343,476,473 :mad . You can, however, look online from a translator. (http://babelfish.altavista.com)

I'm not completely sure, though. Hopefully there is a way.
