I have a BM Technic cable and software which worked fine with my old E46, I've not had any need to use it on my E92 for the last 4 years so have never tried. Its now looking like my bloody throttle actutors have a problem and so I figured I'd use the old cable. However no matter what I do it won't read anything from the car? It just says that no response from the control unit? Am I missing something? Cheers!
