The DME (Digital Motor Electronics) is located on the passenger side in the firewall. there is a cover held on by a few screws. Inside there you will find the DME, and the EGS (transmission, if an auto). They'll be labeled as such. There is a sticker on the DME, with the BMW basic part number, and programmed control unit number, and I think one more, but I'm not sure.
See if any of those match your application. As far as suggestions on aftermarket stuff, I don't go there.
