That's the actual EGS which is just the German abbreviation for "Electronic Gearbox Control". Unfortunately you hit pretty much the worst case as the 8-speed EGS in the E70 cannot be replaced with a used one (I think there's one Russian that can do it if you send the EGS to them by mail). On RealOEM, it looks like it is not available separately and instead part of the mechatronics (computer + valve body) - part 24348687798
