Been slacking on keeping up with the progress here. Manual swap is all done now, was all reasonably straight forward. Installed a lightened SMF, 550i clutch, all new shifter bushings, m performance short shift kit, braided clutchline, removed the CDV and swapped to a large case 3.08diff with a Quaife ATB LSD in it. Everything works like an OEM manual car, no lights, no errors, cruise control works, reverse lights, mirror dips when going into reverse etc.
